6. Letter from Kevin Ryan to Frank Gayle. (November 11, 2004) Ryan, an executive at Underwriters Laboratories ("UL"), wrote to Frank Gayle, the head of the NIST team investigating the World Trade Center collapses -- which is due to issue a draft of its final report in January. UL certified the steel used in building the World Trade Center, and has since tested steel recovered from the Ground Zero site, and also created a model of part of the towers to test the effects of fire on the steel arrays at the WTC. Ryan's letter raises the possibility that the collapse of the Twin Towers was not caused solely by the fuel fires weakening the metal structure. Ryan is not the first scientist to raise common-sense objections to this widespread account, which apparently also has its supporters at NIST. Although Ryan wrote on his own behalf -- his letter is not a company statement -- he does suggest incipient conflicts between UL and NIST with regard to the cause of the collapses. We respectfully call upon the Attorney General to seek advice from UL as well as other independent scientific organizations to resolve whether a steel-beam building can collapse from the relatively foreseeable scenario of a fire fueled by hydrocarbon fuels (including the type that were, apparently, stored in Building 7). If such an independent investigation resolves the issue in favor of the common account attributing the collapses to the effects of fires, the AG should investigate whether other skyscrapers in New York are vulnerable to collapse from fire; and how many others are storing materials that, if exposed to fire, will cause steel beams and structures to fails. (See, Appendix B6)

This little bit of bull$hit is indicative of the intellectual dishonesty of 9/11 CTists. Yeah if the truth isn't on your side bend it till it does.

1) Ryan was head of a UL water testing facility, funny how the CTs ALWAYS seem to omit that. Thus him working for the same company that certefied the WTC's steel is obviously totally irrelevant. He would have standing if he had any metallurgy experience with another company. Saying he worked for UL and not pointing out his work had nothing to do with material certification or metals is intentionally misleading.

2) Saying in his letter he "suggests incipient conflicts between UL and NIST" is more BS - misleading at the least because the author fails to mention he got canned because UL totally repudiated his views.

3) The author claims Ryan's analysis "apparently also has its supporters at NIST" sure and I'm Santa Claus. Any evidence to support this claim?

4) Ryan is referred to as a "scientist" but IIRC he was an administrator not a scientist (though I'm not too sure about this.

5) Saying the AG should consult UL is stupid. UL made their position clear when they fired Ryan. No need to consult "other independent scientific organizations " every scientist with relevent expertise agrees with NIST

Another example of CT's being misleading is their report of Silversteins infamous "pull it" comment. Funny how they almost always forget to mention he was talking to the fire chief and edit the quote as much as possible to furthur remove it from it's context.

Lenbrazil is SOOOO Far behind in this discussion. that he thinks he is 'leading' with this already-refuted straw-man nonsense.

Because of Ryan's letter, (and the ensuing publicity)... the NIST report was delayed for months, and when the 'updated' DRAFT version was produced for 'public discussion', it confirmed exactly the issues that Ryan brought up... (pretending that they had 'discovered' this on their own).

Either catch up, or go back to the moon, Lenny boy.

Foxx even if what you are saying is true is it has nothing to do with my points that the page that Brian cited was deceptive. The only part that could be contradicted was the part about people at NIST being swayed by Ryan's argument.

I assume you can cite some evidence to back your version of events

You think my nonsense has been refuted, well go ahead and try to refute it. Who ever wrote that page was misleading his (or her) readers and that was probably intentional.

You say it was a "straw-man", I don't think you know what the expression means. A straw-man argument is when one party in a debate claims that the other said something they didn't e.g. if I said "foxx believes that the WTC was destroied by a ray gun, he is obviously a tinfoil-hat" that would be a straw-man argument because you never said that. That bit about Ryan was written by a CT, appeared on a CT site and posted here by a CT.

Give it up Foxo every time you try to embarrass me I make fool of you or more accurately you make a fool of yourself. LOL

If you truly believe everything you have posted on this thread, then I would agree that you have not in actual fact lied and I apologize for suggesting you had. Your attitude and approach make it appear that honesty is not your priority. You could have a civil discussion if that was what you actually wanted. It is not necessary to call them as you see them and an honorable discussion refrains from doing so even when the opportunity is present.

That's the problem with the Internet Lon, its open to every nut case as well as those who want "honorable discussion".

If you go back to the beginning of this thread you will see I started out TRYING to have what you call "honorable discussion". I stand by EVERY post I have made and I have admitted to being in error on the few occasions where my posts have been shown to be factually incorrect. NO post has EVER been made where I KNEW WHEN I POSTED IT that it was in error.

I reserve the term LIAR for those who knowingly distort the truth to make it appear to support their position. Foxx has done this repeatedly, and its been pointed out many times. Search on Foxx and LIE and you can track a number of these cases. You will also see the times I corrected Foxx, but did not call him a liar, since it appeared to be an honest mistake (i.e. the distance the Bankers Trust building was from WTC 2), but other areas, like his REPEATED claim that NIST had examined 80% of the steel from the Towers was a LIE that he manufactured by twisting the words in the NIST report to suit his purposes.

In any case, as this thread has progressed I have been called just about every name in the book. To most of the CTers I'm supposedly a government shill hired to, I guess, argue with them. To others, I'm complicit in the attacks.

The discussion is now mostly down to a moronic level since most intelligent posters have given up. It really doesn't seem to matter to most of the CT posters what the FACTS are. Supposition is enough. What most of the CTers post as evidence is totally lame. It is OBVIOUS that most of them hate either America or the current Administration or the NWO or PNAC etc etc. While some are probably Al Qaeda/Muslim supporters I think most are just young men who are easily "riled up". When one of the key CT'ers posts for months, but then ADMITS he hasn't read the NIST report, you know the level of discussion is not going to improve and the person is not really interested in a honest discussion. I suspect that many don't believe what they are posting but think the "end justifies the means". You can see it in so many of the posts calling for us to "hang those really responsible".

As to the moronic "evidence"?

A small blast of air/debris IS a SQUIB. Why? Based on WHAT evidence?

A hunk of concrete and rebar claimed to be "slag".

Rivers of Steel? Where? Based on WHAT evidence?

Pyroclastic Flow? Get real, people were walking around in the blast, temps over 100C would be FATAL. Over 265C and all the paper would ignite. But people claim it was a PYROclastic flow????

Average size of the WTC debris is 60 microns? Based on WHAT? An EPA study on health effects that first SIEVED the material?

Flashes from a Helo taken from 2 miles away COULDN'T be their SEARCHLIGHT, they were most likely SHOULDER FIRED MISSILES????

Flashes become BRIZANT flashes and nobody on the CT side points out that Brizant is not a legitimate way of categorizing a FLASH, as it PRESUPPOSES the flash is from an EXPLOSION.

Powerdization of Spires by a MicroNuke???

Towers fell FASTER than free fall because they were sucked down by a vacuum????

Tons and Tons of Thermite in the basement????

No steel EXPOSED to over 600C???

Lon, it just goes ON and ON. Moronic arguments with NO evidence to support them and, being this is a PHYSICS board, no physics either.

So you might notice that I don't categorize EVERYONE who is supporting a CT idea as moronic. I do try to save it for those who post MULTIPLE MORONIC ideas over time.

Being wrong about something doesn't have to be the same as being DUMB, but a fair number of posters on the CT side act like stupidity is a virtue.

Minor point, Guiliani didn't "PASS A LAW", he apparently issued an executive order, one that I don't believe would hold up in court. Thus my claim that it would be an illegal law.

Still, like you say, that doesn't mean the NYC police won't inforce an illegal law.

And I never said, nor meant to imply that any old Joe Blows off the street were walking inside GZ, freely taking pictures.

What I said was:

Now this had NO IMPACT ON THE MANY PHOTOGRAPHERS that WERE allowed free run of the WTC area, who also took many detailed, hi-res pictures all the way until the site was cleared.

Which is why my argument, that THERE SHOULD HAVE BEEN PICTURES is still VALID.

not stupidity, arthur, but innocence. as in, not bringing preconcieved notions to the table. of course, you will disagree and say that "CT's" believe everything that supports their paranoid delusions.
well, some of us would like this all to just be a scenario that actually matches the pictures. that's all.

i could give great conspiracy theory.

how about this.....

george bush and the bush nazi legacy are actually GOOD, because they are organising power structures, so that when the REAL enemy comes, (from outer space), humanity will be bonded into one lean mean fighting machine. or, maybe it's not nazis, but rather the opponents of the benevolent opus dei and jesuit illuminati.

perhaps the tortured and mind controlled children of the CIA, you know, the army of manchurian candidates that they created, are actually our greatest asset, because they are immune to alien mind manipulation.

or....

maybe there are no aliens. there is just the secret knowledge that earth will be made unliveable on the surface(circa. 2012). the real need to focus on the survival of all of mankind forces the 'tough love' that is used to decide who survives, and who dies, without a bunch of ineffecient debate amongst 'bleeding heart liberals' and other 'tree-huggers'.

or....

the banking balloon is about to bust. 'they' are merely preparing for the social unrest that is about to explode on earth, as the bankers fight to hold their supremacy over common sense(that being the collectively accepted myth that 'money' is real important, while 'people' are not).

or....

or perhaps a bunch of military zealots read 'the report from iron mountain', and decided it best to just stick with the wartime economy, as a peacetime economy is too dangerously untried.

or...
perhaps the saudis and the chinese have teamed up to bully america, and america has no choice but to fake terror in order to be able to start shooting their enemies with 'justification', the alternative being spiralling down into the slave-state status of a third-world country.


perhaps stupidity is a virtue(ignorance is bliss), but i rather prefer the 'spin' that intelligence is a great burden and responsibility.

Well newt, many of us think the NIST scenario matches the pictures.

What ARE THE REASONABLE POTENTIAL OUTCOMES that you might expect when a 767 crashes at very high speed into the upper floors of a large steel skyscraper with no reinforced concrete core that relies on sprayed on fire insulation for protection from prolonged fires and no effective way to fight the fires?

We could SEE the extensive damage done to the perimeter columns.

NIST modeled the terrible damage done to the floors and core columns.

Do you disagree with their IMPACT model?

NIST modeled the spread of the fires, matching it to the pictures we could see of the fires spread. They built office models, floor models etc etc. The fire model they used has been under development for over 2 decades.

Do you disagree with the FIRE model?

They built a GLOBAL model that used the input from the impact model and the fire model and showed how the building progressed to the point of failure.

Do you disagree with the Global model?

See, this is the point, so far only Gordon has posted anything that attempts to contradict the NIST report, and even he admits he has a lot more work to do. I'm sure of it. The NIST report is just too detailed and been publicly reviewed too many times to have some major unexposed flaw in it.

The fact is COLLAPSE is a reasonable potential outcome of the jet impact and subsequent fires. NIST shows how it progressed in GREAT detail, which is why there is NO HUE AND CRY from the structural engineers in the world that the NIST report is wrong.

Its not ONLY that I believe the NIST report, its that I don't see ANYONE with valid credentials SHOWING where it is in error.

------------15%?

NIST modeled the terrible damage done to the floors and core columns.

------------and kept adjusting the input to 'most severe', using imaginary numbers(this is ADMITTED in the report).

Do you disagree with their IMPACT model?

----------the oscillations of the tower after impact were measured as nearly the same as pre-impact, ie. the main structure was hardly affected at all. the redunancy and the 'millipede' or 'mosquito net' structure of the tower was such that any catatrophic loss of structural strength in one area, or even MULTIPLE AREAS, could EASILY be shunted onto adjacent 'pathways' of support.

NIST modeled the spread of the fires, matching it to the pictures we could see of the fires spread. They built office models, floor models etc etc. The fire model they used has been under development for over 2 decades.


Do you disagree with the FIRE model?

-------------yes. they did not account for the 'heat sink' effect in their 'real world' physical experiments, nor the 'ventalation' factor. the actual measured effects of heat on the steel do not match the 'predictions' of the FANCY VIDEO GAME.

They built a GLOBAL model that used the input from the impact model and the fire model and showed how the building progressed to the point of failure.

Do you disagree with the Global model?

------------obviously.

See, this is the point, so far only Gordon has posted anything that attempts to contradict the NIST report, and even he admits he has a lot more work to do. I'm sure of it. The NIST report is just too detailed and been publicly reviewed too many times to have some major unexposed flaw in it.

Bazant Zhou's paper included an "elastic dynamic analysis" part that was completely misleading, since it failed to mention in what a tiny domain it had any validity.

If you are traveling down a highway at 60 mph, then plow into a stalled truck, for a fraction of a second, you will indeed continue to travel at 60 mph. To suggest that, 3 seconds after impact, you will still be traveling at 60 mph is absurd.

Whether or not the NIST report stands the test of time, remains to be seen.

Even so, their complete failure to model, even in an approximate fashion, what happened even 36 meters after collapse ensued in no way allows anybody to credibly claim that the implied collective intuition of the NIST staff regarding what comes after has any validity, whatsoever.

As has been pointed out by many FEMA Fairy Talers, these collapses were first of a kind in many aspects. Thus, intuition (understood as deriving from experience in similar situations) is particularly suspect.

If you are going to believe this, you may as well believe in Bazant Zhou's "elastic dynamic analysis" was valid 1 second after their version of collapse ensued (after granting a free fall through 3.7 meters)

Scholars for 911 Truth has grown rapidly, at least so far, and hopefully they will eventually be able to do some of the work that NIST did not.

Once again, I ignore anomalous aspects which no agent of the US government is likely to touch, ever. Contradicting the intuition of NIST's staff, even on it's own terms, is something I consider likely, but nevertheless distinct from contradicting the gravity driven collapse Fairy Tales, in toto. Even a failure to do the former would in no wise make the latter undoable.

I forgot about his because he is not mention on a lot of CT sites. I think that's because they realize that his story did fit what happened. he said bombs went off in the basement well before the tower collapsed from the top down.

what people who 'slag' ryan seem to fail to notice, is that he had access to the data, and his arguments are true.

OF COURSE, he was FIRED, because the people who HIRED him are GUILTY of TREASON, and he was unwittingly EXPOSING that fact.
ryan's mistake, like many NON-CONSPIRACY theorists' mistake, was to assume that the 'corporation' he worked for CARES about 'money'. 'money' is something 'granted' to 'knights' of the 'royal court' of 'bankers and industrialists'(i guess that last one doesn't need 'quotes'.).

Can you provide any evidence to back this claim?


Len, I thought you said you've been researching this for years? And you've never heard of William Rodriguez? He was honored as a national hero for his resue efforts on September 11. He worked in the towers for 18 years and he and several of his former co-workers are convinced that the buildings were brought down with explosives. Last I heard he was suing the Bush administration.

If you need proof that he exists, try a search engine.

I never said I've been researching this for years. You're right I forgot about "Bombs in the basement" Rodriguez OK say you got one guy. You used plural. Thousands of people escaped the towers and only one thinks it was CD?

I forgot about his because he is not mention on a lot of CT sites. I think that's because they realize that his story did fit what happened. he said bombs went off in the basement well before the tower collapsed from the top down.


Len, please accept my apologies. I re-read your post and indeed you wrote that you've researched this topic for "countless hours" - not years. Big difference. Sorry about that.

The 'plural' would be referring to two of Rodriguez' former co-workers (WTC maintenance workers) who share his views on the towers' destruction.

NOTE: In the following, I use the abbreviation "OCT" to denote "Official Conspiracy Theory" (ie. the theory promulgated by CNN, the U.S. Government, FEMA and NIST). Those who are new to the molten steel question may wish to view this page: (an article written by me which summarises the substantive issues):

http://www.911oz.com/link.phtml?id=66&nav_id=navbutt_66

I have been following the debate on this topic at physorg, and have noted that the OCT'ers have shifted ground somewhat. Initially, the OCT position was flat out denial. They agreed that the steel was hot, but disputed the claim that it was molten. The new OCT position seems to be that a type of spontaneous "friction welding" occured during the collapse, producing enough heat to melt many steel beams.

Well, I thought it might be worth creating a new thread to focus on the scientific merit of this new OCT proposition. I am willing to be persuaded that this is indeed possible, but I suggest the argument needs to deal with the following:

1) The steel was buried in a mountain of concrete dust and rubble. Surely this, in itself, would tend to snuff out the fire, (imagine pouring a bucket of sand on a camp fire burning on the beach).

2) The reports suggest that the molten steel was deep underground - ie. in the basement levels, but, according to the OCT, there were no fires burning in the basement levels prior to the collapse.

3) From what I understand of friction welding technology, it is commonly used to produce "plasticised", (but not molten) metal in order to join components:

QUOTE

Traditionally, friction welding is carried out by moving one component relative to the other along a common interface, while applying a compressive force across the joint. The friction heating generated at the interface softens both components, and when they become plasticised the interface material is extruded out of the edges of the joint so that clean material from each component is left along the original interface. The relative motion is then stopped, and a higher final compressive force may be applied before the joint is allowed to cool. The key to friction welding is that no molten material is generated, the weld being formed in the solid state.


In view of the fact that the WTC steel was literally immersed in sea of dust as it fell, and without the highly controlled conditions of a friction welding apparatus, is it likely that the steel beams would spontaneously rub up against each other to the degree necessary to melt or evaporate them?

No arthur, your argument is not valid.

"Absence of evidence... is NOT... 'evidence' of absence".

You are trying to argue a 'negative'.

Your 'evidence' is 'proof' of nothing.

Yes, it's a good sophist response, and entails a certain amount of 'plausibility', but plausibility is NOT proof nor evidence one way or another.

The 'fact' that actual photos of these "rivers of molten metal" are not plastered all over the libraries and the web 'Currently', do not prove that they don't exist.

I have been searching for thousands of hours, and (like you say) found 'nothing' in the form of video/photographic evidence remotely resembling such anomalies...

Previously, the greatest 'evidence' that was presented was from the much quoted Alex Jones piece... which was seriously attacked...

until I saw the photo (and attached video) on Professor Jones' page]...

This was NEWS to me... (I had never seen such photos before)... and they only confirmed my suspicions further.

Notice the color of the lower portion of this metallurgical sample... It appears to me to be in the yellow to salmon-colored range. As I have stated before, I am NOT a photo-expert ... and the picture is not perfectly clear, but it almost seems to me that the metallurgical sample is drawn out like taffy from where the piece was pulled. Perhaps it was so hot, that this particular sample simply melted away from the other end to which it was attached while still buried?

Now, WHY don't we see pictures of "rivers of molten metal" which were described by so many witnesses?

(Notice that these 'witness testimonies' are not posted on CT sites. Most are from organizations which had first-hand experience at GZ...)

As a 'refresher' here is the list again...

http://forum.physorg.com/index.php?showtop...indpost&p=65201

We know for a fact that NIST has collected thousands of videos and photographs from 9/11. Do these photos exist in the NIST library? I don't know... and neither do you.

I suspect that they have numerous other photos similar to the above (and may in fact have actual photos of the witness-reported "rivers of molten metal")... yet...

I can not offer absolute solid evidence that they DO have these photos... any more than you can 'prove' (by the negative), that they DON'T. All we have to go on 'currently' is the testimony of numerous (non-CT) witnesses.

So your point that you are trying to make that ..."because we currently do not have access to the full NIST library"... we can not show evidence one way or another is nonsense.

Your 'point' has NO merit, and is NOT VALID at all.

It Will Cost All That Makes Us America

What’s really going on here?!? I feel like the child in the story of the Emperor’s New Cloths who knows something stinks while everyone else in the story panders and praises the wonderful cloths worn by the emperor who was really naked for all to see. Deep down most people know the 9/11 terrorist event was just too convenient for this administration and it’s Iran-Contra war-party hawks. Not only is this illegitimate Supreme Court appointed dictatorship made legitimate by 9/11, but the hawks were able to ‘send us all a message’, saying, "If you don’t want another 9/11, you better let us have our wars". Now we are about to start a war against a pre-defeated regime in Iraq with the arrogant presumption that it is our responsibility to change the regime. There was once a time when America abhorred the idea of attacking another country out of the blue because we felt the leader had to die. On top of this is the evidence under my nose that we have set Iraq up for this from the beginning. It’s no secret that America these days only attacks defenseless countries, which have been pummeled mercilessly with the latest in bomb technology. That has been the landscape in Iraq since the end of a war 12 years ago where controversial No-fly zones have been maintained by America and Briton. The hypocrisy of our self-righteous need to wage war with Iraq is underscored by the only female US Ambassador to a Muslim country telling Soddam Hussein that America wouldn’t mind it if he invaded Kuwait in response to Kuwait’s aggression of slant drilling Iraq’s oil. Let’s also not forget that those gas attacks used to kill Kurds, (which we mention constantly to justify our cause), were at the time defended by non other than Donald Rumsfield before the UN in the first Bush administration. In fact the same old Iraq war players are conspicuously now our new Iraq war players; Cheney, Rumsfield, and Wolfowitz to name only three. What’s happening here? The Bush Presidency can now be credited with a Fatherland Security Agency to rival the USSR’s old KGB, a USA Patriot Act to replace our ‘irrelevant’ constitution, pre-emptive strike policies worthy of Hitler’s envy, a secret government, assassinations and regime change as accepted foreign policy, and an undeclared war pitting intimidation against terrorism. What next, concentration camps for poor people and potheads? This is not the America I was raised to believe in, however it is exactly what us conspiracy advocates have been warning of for decades.

Much of the white 'smoke' was probably steam (actually fine water droplets since steam itself is invisible). Water was sprayed on the site in the weeks after the collapse to try to keep particulates in the air to a minimum.

The fact is COLLAPSE is a reasonable potential outcome of the jet impact and subsequent fires. NIST shows how it progressed in GREAT detail, which is why there is NO HUE AND CRY from the structural engineers in the world that the NIST report is wrong.

Its not ONLY that I believe the NIST report, its that I don't see ANYONE with valid credentials SHOWING where it is in error.

Arthur

The report stops the computer simulation when the building is “poised for collapse” even after using all the worst case variables. It proves absolutely nothing so there is no point in showing the errors. If NIST simulated the initial or total collapse, it would be a totally different situation.

That's what it looks like to me, too. Bright-yellow steel would have to be pretty easily torn like that.

Saying the fires burning underground would have burned freakishly hot is silly. Anything burning under tons of mostly-fine rubble would be starved of air, not fed like in a blast furnace.

The temperature of the material pictured above is prima facie proof. And this picture was taken weeks after 9/11. Denying that it's there is childish.

Can someone who believes there were not temps of over 1000C under the rubble (several weeks after 9/11), please show us some precedent for this "spontaneous self-sustaining buried blast furnace" theory?




The "white smoke" is probably steam, IMO also.

Who Will Save America?
My Epiphany

By Paul Craig Roberts
2-7-6

A number of readers have asked me when did I undergo my epiphany, abandon right-wing Reaganism and become an apostle of truth and justice.

I appreciate the friendly sentiment, but there is a great deal of misconception in the question.

When I saw that the neoconservative response to 9/11 was to turn a war against stateless terrorism into military attacks on Muslim states, I realized that the Bush administration was committing a strategic blunder with open-ended disastrous consequences for the US that, in the end, would destroy Bush, the Republican Party, and the conservative movement.

My warning was not prompted by an effort to save Bush's bacon. I have never been any party's political or ideological servant. I used my positions in the congressional staff and the Reagan administration to change the economic policy of the United States. In my efforts, I found more allies among influential Democrats, such as Senate Finance Committee Chairman Russell Long, Joint Economic Committee Chairman Lloyd Bentsen and my Georgia Tech fraternity brother Sam Nunn, than I did among traditional Republicans who were only concerned about the budget deficit.

My goals were to reverse the Keynesian policy mix that caused worsening "Phillips curve" trade-offs between employment and inflation and to cure the stagflation that destroyed Jimmy Carter's presidency. No one has seen a "Phillips curve" trade-off or experienced stagflation since the supply-side policy was implemented. (These gains are now being eroded by the labor arbitrage that is replacing American workers with foreign ones. In January 2004 I teamed up with Democratic Senator Charles Schumer in the New York Times and at a Brookings Institution conference in a joint effort to call attention to the erosion of the US economy and Americans' job prospects by outsourcing.)

The supply-side policy used reductions in the marginal rate of taxation on additional income to create incentives to expand production so that consumer demand would result in increased real output instead of higher prices. No doubt, the rich benefitted, but ordinary people were no longer faced simultaneously with rising inflation and lost jobs. Employment expanded for the remainder of the century without having to pay for it with high and rising rates of inflation. Don't ever forget that Reagan was elected and re-elected by blue collar Democrats.

The left-wing's demonization of Ronald Reagan owes much to the Republican Establishment. The Republican Establishment regarded Reagan as a threat to its hegemony over the party. They saw Jack Kemp the same way. Kemp, a professional football star quarterback, represented an essentially Democratic district. Kemp was aggressive in challenging Republican orthodoxy. Both Reagan and Kemp spoke to ordinary people. As a high official in the Reagan administration, I was battered by the Republican Establishment, which wanted enough Reagan success so as not to jeopardize the party's "lock on the presidency" but enough failure so as to block the succession to another outsider. Anyone who reads my book, The Supply-Side Revolution (Harvard University Press, 1984) will see what the real issues were.

If I had time to research my writings over the past 30 years, I could find examples of partisan articles in behalf of Republicans and against Democrats. However, political partisanship is not the corpus of my writings. I had a 16-year stint as Business Week's first outside columnist, despite hostility within the magazine and from the editor's New York social set, because the editor regarded me as the most trenchant critic of the George H.W. Bush administration in the business. The White House felt the same way and lobbied to have me removed from the William E. Simon Chair in Political Economy at the Center for Strategic and International Studies.

Earlier when I resigned from the Reagan administration to accept appointment to the new chair, CSIS was part of Georgetown University. The University's liberal president, Timothy Healy, objected to having anyone from the Reagan administration in a chair affiliated with Georgetown University. CSIS had to defuse the situation by appointing a distinguished panel of scholars from outside universities, including Harvard, to ratify my appointment.

I can truly say that at one time or the other both sides have tried to shut me down. I have experienced the same from "free thinking" libertarians, who are free thinking only inside their own box.

In Reagan's time we did not recognize that neoconservatives had a Jacobin frame of mind. Perhaps we were not paying close enough attention. We saw neoconservatives as former left-wingers who had realized that the Soviet Union might be a threat after all. We regarded them as allies against Henry Kissinger's inclination to reach an unfavorable accommodation with the Soviet Union. Kissinger thought, or was believed to think, that Americans had no stomach for a drawn-out contest and that he needed to strike a deal before the Soviets staked the future on a lack of American resolution.

Reagan was certainly no neoconservative. He went along with some of their schemes, but when neoconservatives went too far, he fired them. George W. Bush promotes them. The left-wing might object that the offending neocons in the Reagan administration were later pardoned, but there was sincere objection to criminalizing what was seen, rightly or wrongly, as stalwartness in standing up to communism.

Neoconservatives were disappointed with Reagan. Reagan's goal was to END the cold war, not to WIN it. He made common purpose with Gorbachev and ENDED the cold war. It is the new Jacobins, the neoconservatives, who have exploited this victory by taking military bases to Russian borders.

I have always objected to injustice. My writings about prosecutorial abuse have put me at odds with "law and order conservatives." I have written extensively about wrongful convictions, both of the rich and famous and the poor and unknown. My thirty-odd columns on the frame-up of 26 innocent people in the Wenatchee, Washington, child sex abuse witch hunt played a role in the eventual overturning of the wrongful convictions.

My book, with Lawrence Stratton, The Tyranny of Good Intentions, details the erosion of the legal rights that make law a shield of the innocent instead of a weapon in the hands of government. Without the protection of law, rich and poor alike are at the mercy of government. In their hatred of "the rich," the left-wing overlooks that in the 20th century the rich were the class most persecuted by government. The class genocide of the 20th century is the greatest genocide in history.

Americans have forgotten what it takes to remain free. Instead, every ideology, every group is determined to use government to advance its agenda. As the government's power grows, the people are eclipsed.

We have reached a point where the Bush administration is determined to totally eclipse the people. Bewitched by neoconservatives and lustful for power, the Bush administration and the Republican Party are aligning themselves firmly against the American people. Their first victims, of course, were the true conservatives. Having eliminated internal opposition, the Bush administration is now using blackmail obtained through illegal spying on American citizens to silence the media and the opposition party.

Before flinching at my assertion of blackmail, ask yourself why President Bush refuses to obey the Foreign Intelligence Surveillance Act. The purpose of the FISA court is to ensure that administrations do not spy for partisan political reasons. The warrant requirement is to ensure that a panel of independent federal judges hears a legitimate reason for the spying, thus protecting a president from the temptation to abuse the powers of government. The only reason for the Bush administration to evade the court is that the Bush administration had no legitimate reasons for its spying. This should be obvious even to a naif.

The United States is undergoing a coup against the Constitution, the Bill of Rights, civil liberties, and democracy itself. The "liberal press" has been co-opted. As everyone must know by now, the New York Times has totally failed its First Amendment obligations, allowing Judith Miller to make war propaganda for the Bush administration, suppressing for an entire year the news that the Bush administration was illegally spying on American citizens, and denying coverage to Al Gore's speech that challenged the criminal deeds of the Bush administration.

The TV networks mimic Fox News' faux patriotism. Anyone who depends on print, TV, or right-wing talk radio media is totally misinformed. The Bush administration has achieved a de facto Ministry of Propaganda.

The years of illegal spying have given the Bush administration power over the media and the opposition. Journalists and Democratic politicians don't want to have their adulterous affairs broadcast over television or to see their favorite online porn sites revealed in headlines in the local press with their names attached. Only people willing to risk such disclosures can stand up for the country.

Homeland Security and the Patriot Act are not our protectors. They undermine our protection by trashing the Constitution and the civil liberties it guarantees. Those with a tyrannical turn of mind have always used fear and hysteria to overcome obstacles to their power and to gain new means of silencing opposition.

Consider the no-fly list. This list has no purpose whatsoever but to harass and disrupt the livelihoods of Bush's critics. If a known terrorist were to show up at check-in, he would be arrested and taken into custody, not told that he could not fly. What sense does it make to tell someone who is not subject to arrest and who has cleared screening that he or she cannot fly? How is this person any more dangerous than any other passenger?

If Senator Ted Kennedy, a famous senator with two martyred brothers, can be put on a no-fly list, as he was for several weeks, anyone can be put on the list. The list has no accountability. People on the list cannot even find out why they are on the list. There is no recourse, no procedure for correcting mistakes.

I am certain that there are more Bush critics on the list than there are terrorists. According to reports, the list now comprises 80,000 names! This number must greatly dwarf the total number of terrorists in the world and certainly the number of known terrorists.

How long before members of the opposition party, should there be one, find that they cannot return to Washington for important votes, because they have been placed on the no-fly list? What oversight does Congress or a panel of federal judges exercise over the list to make sure there are valid reasons for placing people on the list?

If the government can have a no-fly list, it can have a no-drive list. The Iraqi resistance has demonstrated the destructive potential of car bombs. If we are to believe the government's story about the Murrah Federal Office Building in Oklahoma City, Timothy McVeigh showed that a rental truck bomb could destroy a large office building. Indeed, what is to prevent the government from having a list of people who are not allowed to leave their homes? If the Bush administration can continue its policy of picking up people anywhere in the world and detaining them indefinitely without having to show any evidence for their detention, it can do whatever it wishes.

Many readers have told me, some gleefully, that I will be placed on the no-fly list along with all other outspoken critics of the growth in unaccountable executive power and war based on lies and deception. It is just a matter of time. Unchecked, unaccountable power grows more audacious by the day. As one reader recently wrote, "when the president of the United States can openly brag about being a felon, without fear of the consequences, the game is all but over."

Congress and the media have no fight in them, and neither, apparently, do the American people. Considering the feebleness of the opposition, perhaps the best strategy is for the opposition to shut up, not merely for our own safety but, more importantly, to remove any impediments to Bush administration self-destruction. The sooner the Bush administration realizes its goals of attacking Iran, Syria, and the Shia militias in Lebanon, the more likely the administration will collapse in the maelstrom before it achieves a viable police state. Hamas' victory in the recent Palestinian elections indicates that Muslim outrage over further US aggression in the Middle East has the potential to produce uprisings in Pakistan, Egypt, Jordan, and Saudi Arabia. Not even Karl Rove and Fox "News" could spin Bush out of the catastrophe.

Perhaps we should go further and join the neocon chorus, urging on invasions of Iran and Syria and sending in the Marines to disarm Hizbullah in Lebanon. Not even plots of the German High Command could get rid of Hitler, but when Hitler marched German armies into Russia he destroyed himself. If Iraq hasn't beat the hubris out of what Gordon Prather aptly terms the "neo-crazies," US military adventures against Iran and Hizbullah will teach humility to the neo-crazies.

Many patriotic readers have written to me expressing their frustration that fact and common sense cannot gain a toehold in a debate guided by hysteria and disinformation. Other readers write that 9/11 shields Bush from accountability, They challenge me to explain why three World Trade Center buildings on one day collapsed into their own footprints at free fall speed, an event outside the laws of physics except under conditions of controlled demolition. They insist that there is no stopping war and a police state as long as the government's story on 9/11 remains unchallenged.

They could be right. There are not many editors eager for writers to explore the glaring defects of the 9/11 Commission Report. One would think that if the report could stand analysis, there would not be a taboo against calling attention to the inadequacy of its explanations. We know the government lied about Iraqi WMD, but we believe the government told the truth about 9/11.

Debate is dead in America for two reasons: One is that the media concentration permitted in the 1990s has put news and opinion in the hands of a few corporate executives who do not dare risk their broadcasting licenses by getting on the wrong side of government, or their advertising revenues by becoming "controversial." The media follows a safe line and purveys only politically correct information. The other reason is that Americans today are no longer enthralled by debate. They just want to hear what they want to hear. The right-wing, left-wing, and libertarians alike preach to the faithful. Democracy cannot succeed when there is no debate.

Americans need to understand that many interests are using the "war on terror" to achieve their agendas. The Federalist Society is using the "war on terror" to achieve its agenda of concentrating power in the executive and packing the Supreme Court to this effect. The neocons are using the war to achieve their agenda of Israeli hegemony in the Middle East. Police agencies are using the war to remove constraints on their powers and to make themselves less accountable. Republicans are using the war to achieve one-party rule--theirs. The Bush administration is using the war to avoid accountability and evade constraints on executive powers. Arms industries, or what President Eisenhower called the "military-industrial complex," are using the war to fatten profits. Terrorism experts are using the war to gain visibility. Security firms are using it to gain customers. Readers can add to this list at will. The lack of debate gives carte blanche to these agendas.

One certainty prevails. Bush is committing America to a path of violence and coercion, and he is getting away with it.

Len, please accept my apologies. I re-read your post and indeed you wrote that you've researched this topic for "countless hours" - not years. Big difference. Sorry about that.

The 'plural' would be referring to two of Rodriguez' former co-workers (WTC maintenance workers) who share his views on the towers' destruction.

Even though it was “countless hour” and not “years”, “Who ever wrote that page (post) was misleading his (or her) readers and that was probably intentional.”

I added (post) to lenbrazil quote.

Amazing how the conspiracy theorists have selective memories. I am no longer responding to someone who claims to research 9/11 and cannot remember William Rodriguez.

You won't reply to my posts any more because I forgot about a witness who claims to have seen (heard) bombs go off even though his story doesn't fit the CD senario? I am heartbroken, won't you please reconsider? Pretty please with a cherry on top. LOL

Do you really think I care one way or the other?

Ok, new question "Are there any survivors from the towers who publicly support the CD theory, whose stories are consistent with a CD senario? I.E. they sey they saw and/or heard explosions that they believe were demolition charges at the time of or immediately before the collapse?

As far as I know the only people who were in either tower when it collapsed were the firemen in the WGBH/BBC/Discovery Channel documentary. They said nothing about bombs.

Len, have you read this thread? Rodriguez' testimony is in no way inconsistent with any number of controlled demolition scenarios. This has already been discussed in this thread. If you haven't read it you might do the rest of us a courtesy and do so, so as not to keep repeating and rehashing.

your argument is not valid.

"Absence of evidence... is NOT... 'evidence' of absence".

You are trying to argue a 'negative'.

Your 'evidence' is 'proof' of nothing.

Yes, it's a good sophist response, and entails a certain amount of 'plausibility', but plausibility is NOT proof nor evidence one way or another.

The 'fact' that actual photos of these "rivers of molten metal" are not plastered all over the libraries and the web 'Currently', do not prove that they don't exist.

I have been searching for thousands of hours, and (like you say) found 'nothing' in the form of video/photographic evidence remotely resembling such anomalies...

Previously, the greatest 'evidence' that was presented was from the much quoted Alex Jones piece... which was seriously attacked...

until I saw the photo (and attached video) on Professor Jones' page]...

This was NEWS to me... (I had never seen such photos before)... and they only confirmed my suspicions further.

user posted image

(note replaced Foxx's sorry picture with CLEAR version)

Notice the color of the lower portion of this metallurgical sample... It appears to me to be in the yellow to salmon-colored range. As I have stated before, I am NOT a photo-expert ... and the picture is not perfectly clear, but it almost seems to me that the metallurgical sample is drawn out like taffy from where the piece was pulled. Perhaps it was so hot, that this particular sample simply melted away from the other end to which it was attached while still buried?

Now, WHY don't we see pictures of "rivers of molten metal" which were described by so many witnesses?

(Notice that these 'witness testimonies' are not posted on CT sites. Most are from organizations which had first-hand experience at GZ...)

As a 'refresher' here is the list again...

http://forum.physorg.com/index.php?showtop...indpost&p=65201

We know for a fact that NIST has collected thousands of videos and photographs from 9/11. Do these photos exist in the NIST library? I don't know... and neither do you.

I suspect that they have numerous other photos similar to the above (and may in fact have actual photos of the witness-reported "rivers of molten metal")... yet...

I can not offer absolute solid evidence that they DO have these photos... any more than you can 'prove' (by the negative), that they DON'T. All we have to go on 'currently' is the testimony of numerous (non-CT) witnesses.

So your point that you are trying to make that ..."because we currently do not have access to the full NIST library"... we can not show evidence one way or another is nonsense.

Your 'point' has NO merit, and is NOT VALID at all.

Actually, after 4 friggin years, absence of evidence is evidence of absence.

And as we know, the WHOLE NIST library is available for a measly $14,000.

here's a thought. they are taking the debris from the TOP of the pile., why would they try and reach down THROUGH debris to REMOVE debris?

so, those roaring temperatures are just below the surface. six wks. later, and, according to you, it would take the energy of tons of thermite to create these temperatures. and you use that as an argument AGAINST demolition. i still don't get it. you claim you "need" all that thermite to create heat, yet are completely willing to ignore that without the thermite, there is residual energy from friction alone or something equally implausible to account for the molten steel.
SIX WEEKS LATER, man! those 'furnaces' obviously had fuel, and the fuel was just below the surface, and there was little or no FLAME, and so it was more likely an ONGOING CHEMICAL REACTION that was keeping things hot.

or maybe, it was a nuke.

Why don’t we then discuses Professor Jones paper criticizing the NIST report, I agree with all his points and have read the report. I am not sure what Metamars means by "what happened even 36 meters after collapse ensued". The simulation does not even start the collapse (model becomes unstable) and is stopped without validation that even a partial collapse will ensue.

13. I have read through the hundreds of pages of the Final NIST report on the collapses of the WTC Towers. (NIST, 2005) It is interesting to note that NIST “decoupled” and delayed their final report on WTC 7, which is overdue as of this writing (NIST, 2005; NISTb, 2005) I agree with some of the NIST report; for example:

QUOTE
Both WTC 1 and WTC 2 were stable after the aircraft impact, standing for 102 min and 56 min, respectively.  The global analyses with structural impact damage showed that both towers had considerable reserve capacity. This was confirmed by analysis of the post-impact vibration of WTC 2… where the damaged tower oscillated at a period nearly equal to the first mode period calculated for the undamaged structure. (NIST, 2005, p. 144; emphasis added.)

At any given location, the duration of [air, not steel] temperatures near 1,000oC was about 15 min to 20 min.  The rest of the time, the calculated temperatures were near 500oC or below.” (NIST, 2005, p. 127, emphasis added.)


QUOTE
NIST contracted with Underwriters Laboratories, Inc. to conduct tests to obtain information on the fire endurance of trusses like those in the WTC towers…  All four test specimens sustained the maximum design load for approximately 2 hours without collapsing.” (NIST, 2005, p. 140, emphasis added.)


However, I along with others challenge NIST’s collapse theory. NIST maintains that all three building collapses were fire-initiated despite the observations above, particularly the fact that fire endurance tests with actual models did not result in collapse. In a paper by fire-engineering experts in the UK, we find:

The basis of NIST’s collapse theory is… column behaviour in fire...  However, we believe that a considerable difference in downward displace between the [47] core and [240] perimeter columns, much greater than the 300 mm proposed, is required for the collapse theory to hold true… [Our] lower reliance on passive fire protection is in contrast to the NIST work where the amount of fire protection on the truss elements is believed to be a significant factor in defining the time to collapse…  The [proposed effect] is swamped by thermal expansion … Thermal expansion and the response of the whole frame to this effect has NOT been described as yet [by NIST].  (Lane and Lamont, 2005.)


QUOTE
I agree with these pointed objections, particularly that the “response of the whole frame” of each building should be considered, especially heat transport to the whole frame from localized fires, and that the “core columns cannot pull the exterior columns in via the floor.”  (Lane and Lamont, 2005)


The computerized models of the Towers in the NIST study, which incorporate many features of the buildings and the fires on 9-11-01, are less than convincing. The Final report states:

The computerized models of the Towers in the NIST study, which incorporate many features of the buildings and the fires on 9-11-01, are less than convincing. The Final report states:

The Investigation Team then defined three cases for each building by combining the middle, less severe, and more severe values of the influential variables. Upon a preliminary examination of the middle cases, it became clear that the towers would likely remain standing. The less severe cases were discarded after the aircraft impact results were compared to observed events. The middle cases (which became Case A for WTC 1 and Case C for WTC 2) were discarded after the structural response analysis of major subsystems were compared to observed events. (NIST, 2005, p. 142; emphasis added.)


The NIST report makes for interesting reading. The less severe cases based on empirical data were discarded because they did not result in building collapse. But ‘we must save the hypothesis,’ so more severe cases were tried and the simulations tweaked, as we read in the NIST report:

QUOTE
The more severe case (which became Case B for WTC 1 and Case D for WTC 2) was used for the global analysis of each tower. Complete sets of simulations were then performed for Cases B and D. To the extent that the simulations deviated from the photographic evidence or eyewitness reports [e.g., complete collapse occurred], the investigators adjusted the input, but only within the range of physical reality. Thus, for instance,…the pulling forces on the perimeter columns by the sagging floors were adjusted...  (NIST, 2005, p. 142; emphasis added.)

The primary role of the floors in the collapse of the towers was to provide inward pull forces that induced inward bowing of perimeter columns. (NIST, 2005, p. 180; emphasis added.)


How fun to tweak the model like that, until the building collapses -- until one gets the desired result. But the end result of such tweaked computer hypotheticals is not compelling, sorry gentlemen. Notice that the“the pulling forces on the perimeter columns by the sagging floors were adjusted” (NIST, 2005, p. 142; emphasis added) to get the perimeter columns to yield sufficiently – one suspects these were “adjusted” by hand quite a bit -- even though the UK experts complained that “the core columns cannot pull the exterior [i.e., perimeter] columns in via the floor.” (Lane and Lamont, 2005; emphasis added.)

Since 9-11 there has been a greater interest in the safety of tall
buildings and how increased safety can be achieved without
compromising on aesthetics or unnecessary costs.
We will discuss how both these can be achieved with an
increase in life safety compared with prescriptive solutions
when fire engineered solutions founded within a risk
assessment are used.
Arup is active in this process in the UK, the americas, in
Australia and in Asia. We intend to closely monitor and
influence the regulatory and design community responses to
tall building safety.
It is our view that the National Institute of Standards and
Technology’s (NIST) report into the events of 9-11 is a critically
important document for tall building design worldwide.

Its conclusions will have a major influence on the Regulatory
environment, and on clients’ expectations for tall building
design. We believe it will provide invaluable data for future
design validation.

That's what it looks like to me, too. Bright-yellow steel would have to be pretty easily torn like that.

Saying the fires burning underground would have burned freakishly hot is silly. Anything burning under tons of mostly-fine rubble would be starved of air, not fed like in a blast furnace.

The temperature of the material pictured above is prima facie proof. And this picture was taken weeks after 9/11. Denying that it's there is childish.

Can someone who believes there were not temps of over 1000C under the rubble (several weeks after 9/11), please show us some precedent for this "spontaneous self-sustaining buried blast furnace" theory?




The "white smoke" is probably steam, IMO also.

I wouldn't rule out thermite reactions in the rubble. The molten aluminum from the aircraft could have reacted with the pulverized concrete, gypsum, and other materials containing oxygen, hydroxide, or water. The burning in that case wouldn't require oxygen from the air, as it is supplied by the materials themselves.
Guest
Water being sprayed on the pit could have made things hotter if it reacted with aluminum or some of the elements of aluminum allots such as magnesium and lithium. We all know that fire crews don't pour water on magnesium fires, as it makes the fire hotter. Drop a piece of potassium, magnesium, or lithium in a bucket of water and watch what happens.

I didn’t read the entire thread but I did a search for Rodriguez and came up with 5 pages of matches. His story isn’t consistent with the CD scenario because he claims the explosions happened just before the plane hit the North Tower or 102 minutes before it’s collapse. I only saw two reasons give for as to why a bomb would be set of in the basement at that time. Neither of these scenarios really makes sense.


1) To destroy the water pump.

He said he was thrown out of his chair (or something to that effect) why would such a strong explosive be needed to make the pump inoperable?

Also if such a strong explosion happened BEFORE the plane stuck their should have been many reports of this starting from 9/11, so far only Rodrigues and 2 of his buddies have said this and only did so after get involved in the Berg lawsuit. Rodriguez gave a different version on 9/11.

How do we know the water pump below where he was?

This should have caused several thousand gallons of water to flood the pump room; there were no reports of this.

It would have made more sense to wait until just after the plane stuck why set it of just before? This would needlessly draw suspicion

2) To damage the core in order to get the building to implode.

This makes even less sense. Why damage the core almost 2 hours before brining down the building? Again why BEFORE the plane struck?

Why didn’t this cause the building to become noticeably unstable or for the core to sag?

The tower collapsed top down, how would weakening the core in the basement induce implosion from the top?

Rodriguez was probably mistaken in his claim there was an explosion in the basement before the plane hit or for some reason is making it up. His changing his story doesn’t add to his credibility which is weaken by lack of corroborating evidence and further strained by a lack of a credible CD scenario which takes it into account. He said he had 14 witnesses who backed his account and on one occasion 27, what happened to them?
Guest
When aircraft in hangars in Iraq were bombed by the U.S., the molten aluminum from the aircraft actually reacted with the concrete floors and left a crater in the concrete. A thermite reaction can occur between the aluminum and the water that is held up in the concrete. It gives off heat and makes the fire even hotter.
gordon
NOWHERE IN THIS DOCUMENT DO THE AUTHORS IMPLY ANYTHING OTHER THEN THE IMPACT AND FIRE WERE RESPONSIBLE FOR THE COLLAPSE.

They do however contradict the key part of NIST's initiation sequence, when they say

the core columns cannot pull the exterior columns in via the floors simply as a result of column shortening

They go into detail on page 9 of the link posted.
If the floors could not pull the exterior columns inwards due to these identified thermal effects, then there must be some other cause or mechanism.
So the question which is left unanswered is, what did pull the columns in and thereby cause the collapse?
G
newton
try this at home, lol.

okay, notice that the metals were POWDERED, and that a THIRD AGENT is required to start the reaction.

you can not simply put aluminum near rust and get a spontaneous thermite reaction.





gordon
The tower collapsed top down, how would weakening the core in the basement induce implosion from the top?

By decreasing the core's ability to carry load and therby increasing, via the hat truss, the load on the exterior columns. This increased load would induce failure, in the first instance, at the weakest point - the point of aircraft impact.
This process is detailed in the recent link posted and referred to in my last post, and also in the NIST report

Show me where the NIST says the core columns pulled on the floor which pulled on the perimeter columns. In fact the NIST goes through great lengths in pointing out sagging floors which pulled the perimeter columns in.

http://www.geocities.com/debunking911/sag.htm

Also, if this didn't happen, how did an explosion pull in the perimeter columns?

Seems like they wanted to prove the NIST wrong by lying about what they're saying. An old republican trick.

This 'moonwalker' (lenbrazil) has spent way too long at Apollo-Hoax debunking a ridiculously silly tin-hat theory that 'We-Never-Went-To-The-Moon'.

Pretty easy to do that...

it also takes about an hour or two of research to completely debunk Phil Jayhans 'Amazing Pod Theory' .

Unfortunately, lenny has fallen into the tin-hat belief that ALL conspiracies are total nonsense (and therefore 'easy' to debunk).

Silly goose has brought his old sophistry 'talents' here to address what appears to be very new to him... (the WTC towers demolition theories). I guess he feels he needs to do NO research at all to debunk these stupid 'CTists'.

With all due respect, lenbrazil... if you want to play 'debunker' here, first you will need to do much more research regarding the NIST reports & history... witness testimonies... actual engineered construction of the buildings... etc.

Good grief, man - you are not even aware of a national hero - Rodriguez !!!

Metamars... you might find the following particularly interesting.

Re-visiting the Thermobaric Bombs Theory...

Given the possible passages for jet-fuel to arrive in the basement levels (at supersonic speed), and finding those theories which depend upon sentient jet-fuel to be highly implausible myself... (especially given that a 'thermobaric bomb depends upon a highly precise volumetric mixture of oxygen in ratio to precise size of kerosene droplets), personally I find this theory quite implausible.

However, after doing some further research on the question of the 'thermobaric explosion' in the basement levels, I have found the following.

As you know, opponents have pointed out (correctly) that a conventional explosive does not produce great fireballs (as popularized by movies).

So, we have faced a conundrum of how the basement explosion could have been merely conventional explosives (RDX / etc), when there is ample witness testimony that 'fireballs' were associated with such explosion(s).

Project METC Summary Report

The chief difference in METC unit (Multiple Explosives Transitional Container) design over traditional explosive devices moves away from a densely packed explosive core towards a large volume of highly explosive but low-density mass in the form of a gaseous cloud. In the normal bomb all explosive energy comes from a tightly packed core and must drive outward against air pressure and objects it encounters. It rapidly bleeds off energy at the square of the distance as it accumulates a wall of pressure resistance and a mass of heavy debris, which it must continually regather and push along.

The new design starts as a small device but transforms itself through simple means from a dense-core technology to a much larger gaseous-cloud state. Igniting the explosive cloud at any peripheral or central point creates a chain-reaction-like and progressively growing explosive force. As the force of the explosion moves outward, it continues to ignite fresh explosive materials as encountered and gains momentum rather than loosing it. Further, because the gaseous cloud is efficiently mixed explosive materials combined with abundant free-air oxygen, ignition is far more complete and productive - leaving little or no chemical residue or traditional flash evidence (other than a burn signature, which any investigator would presume to be from ordinary fire)on immediately encountered objects. The net result is as if a significantly larger central core device had been detonated, with the complete and even combustion making difficult any aftermath analysis as to the true nature of the explosives used. Finally, the shape of the cloud and the ignition point within the cloud, if properly controlled, provides an extremely easy means to create shaped charge effects despite a relatively free-form original cloud shape.

Termed an electro-hydrodynamic gaseous fuel device (fn1), it produces a three-stage explosion through a process described as a highly focused, A-neutronic (fn2) energy transfer. The first detonation would be a small, low-volume explosion provided by just a few ounces of PETN explosive (fn3). This is placed within a relatively small central core shaft suspended from the top of the bomb container such that it is surrounded by a liquid compound of aqueous ammonium nitrate. The core shaft containing the explosive is itself made up of a compressed and hardened compound of aluminum silicate and N2O4, which starts as a slurry prior to application of a high-pressure baking process. Except for the explosive charge protected from external forces within, these items are all safe from accidental detonation as relatively safe-to-handle materials.

The first explosion's sole function is something akin to shaking a warm soda bottle violently with only a thumb to cover the opening. The relatively small explosion providing three key effects: reduction of the inner core shaft to a microfine powder; mixture of the resulting powder and aqueous solution under violently induced pressure in order to cause complete chemical absorption; and force- opening the container to support erruption of contents into a gaseous state. The cylindrical bomb casing, which has precut scores or weak points to insure it ruptures in a sawtooth pattern about its middle, splits into two flowered halves which blossom outward from the pressure. The upper half shoots upward as if shot from a cannon, while the lower portion remains cannon-like and in place on its base.

Milliseconds later, a second explosion of a larger quantity of more powerful PDTN (fn4) material is set off at the bottom of the container. Timing is critical in milliseconds as too-long a delay would allow the flash of the explosion to prematurely ignite the gaseous cloud. This detonation must take place before the cloud has been adequately oxygenated and so expanded as to be reactant to the flash, but delayed to the optimum point for final blast effects.

The ideal detonator would likely be some form of barometric sensing device looking for the changes in pressure as the explosion's forced evacuation begins to drop back towards normal levels. Simple electronic timming devices could work adequately but would not allow optimum performance in field application, as the variables of bomb placement relative to large objects/structures and open/confined spaces can impact on timing needs in incalcuable ways.

This secondary explosive is housed within its own shaped charge container formed into the bottom of the lower bomb casing. The shape and higher force of the second blast forces the bottom of the casing to separate from its base and fly upward. In this action, it will burst open even wider into its own flower petal shape, providing additional turbulent mixing of the forming cloud with free air. The violent turbulence, in turn, causes portions of the cloud to become highly charged electrostatically as it continues to form a huge and turbulent mushroom immediately over ground zero. Explosive potential has now been reached, though optimal performance is dictated by cloud size, shape, and density -- which are again variables effected by the bomb's placement and surroundings.

The cloud is made up of a mixture of the Aqueous Ammonium Nitrate with the pulverized aluminum Silicate and N2O4 compound. Once mixed with each other and free-air oxygen under force of the first two detonations, the resulting cloud is extremely explosive in nature, electrostatically charged, decidedly cold, and awaiting only an opportunity to detonate. The shape of the cloud itself, due to the nature of the cannonade-like upward flight of the upper casing, and the blunter and delayed action of the lower casing, is somewhat tear shaped - though designs can be made to produce other shapes by nature of the original container's design. This can be a key factor in fixing the shape and focus of the blast effect.

In airburst explosions provided by conventional weapons, the blast effect is minimal due to a rapid bleed of energy in all directions as blast radius increases, with only those items beneath ground zero being subjected to blast exposure. Ground explosions, however, provide a means of deflecting otherwise wasted energy into a more desired radial blast effect. In nuclear technology, the reverse is true. A ground blast wastes energy in vaporizing and throwing up of tremendous quantities of ground materials where an air blast expands to maximum heat and blast effect forces before comming into contact with ground objects -- forming a broader circle of maximum impact. An airburst shockwave travels in air, a light medium, whereas the ground burst starts with solid matter thrown up by the blast - a heavier medium. An angular shockwave in a light medium tends to reflect when striking a solid, immovable plane such as the earth. This reradiates the energy outward and back upward (fn5), further enhancing the shockwave effects against any encountered ground structures.

If the resulting METC unit cloud can be triggered from the top down, energy transfer drives the explosion downward and takes advantage of the tear-shape cloud. To repeat, as the force of the explosion moves outward from the ignition point, it continues to ignite fresh explosive materials as encountered and the blast gains momentum rather than loosing. By controlling the original ignition point, the blast effect can become highly focused and magnified. Yet, as an airblast, the outermost zone of actual blast damage is somewhat lessened, limiting collateral damage to a given, focused blast perimeter. This is because the focused energy deflects upward instead of radiating away from ground zero parallel to the ground. Only the secondary shock wave effects would have impact on surrounding or secondary structures or objects -- such as blowing out windows, a peculiar trademark of the device (fn5) which may dictate or limit applications should the nature of the device become public and covert application be required without revealing the type of explosives used. In the case of nuclear technology, the secondary shock wave damage is much more significant due to the massive scale of the original explosive force, and so, the effective radius of the bomb is increased dramatically. METC, unless constructed on a much larger scale, need not be so described.

Where traditional military explosives provide detonation velocities of 7,000-8,100 feet per second at the blast point. These bleed off at the square of the distance from the center of ground zero. The METC unit device, in ideal applications, is capable of much higher performance in the [REDACTED] range over a larger ground zero area equal to cloud diameter -- though destructive forces immediately beneath ground zero are noticably less than at the edge of the cloud and beyond (fn6). Final velocities can be concievably higher with optimal environmental placements, bomb design, and timing. These higher velocities provide several magnitudes greater damage potential as destructive capacity can be said to increase at the square of the force applied.

This weapon would be best applied to specific hard targets (fn7) where maximum localized damage was considered more important than broad-based damaged to broader concentrations of soft targets (fn8). Its unique nature defeats normal aftermath analysis and can therefore be applied in covert actions freely, though some effort to misdirect investigations may be required in order to insure that no undue attention is placed on the unique blast characteristics or the absence of traditional flash evidence and chemical residues.

The third and final explosion, which to an observer would be seen as a second explosion due to the mere milliseconds of delay between the first two, is timed to coincide with maximum effectiveness of the expanding cloud. The cloud's expansion rate falls off at the square of the distance from the explosion (fn9). For a devices relatively small in size, a proper cloud of suitable destructive capability could be achieved in a relatively few seconds initial expansion.

Anything within the targeted blast area, is pulverized by the highly focused nature of what would otherwise be viewed as a relatively small blast. The damage effect is not dissimilar to the visual of an explosion under water, where a violent and rapid expansion takes place and then collapses inward on itself. In this case, however, as are no great hydraulic pressures to contend with, the greatest destruction takes place within a focused perimeter, as a normalized shock wave continues on. The collapse and shock waves, relative to the size of the large-volume gaseous bomb - is a remarkably lesser pressure more in keeping with the size of the original compact device.

Timing is provided by a barometric device (fn10) which senses the normalization in pressures as the cloud thins at the base and air rushes back to fill the void - the point where expansion begins to falter against air seeking to rush back into the void created by the first explosions. Remember the under-water explosion visual. The final detonating device, along with timing controls and bomb activation and triggering mechanisms for the entire weapon, is housed in an bomb base which remains in tact on the ground after the first two explosions. Resting on legs of wood, plastic, or teflon, it is electrically insulated, though there is a ground wire established for the final triggering circuit.

While it contains a battery to operate the initial timing and triggering circuits, it also contains a quartz-crystal-based pizo- electric device (fn10) capable of producing many thousands of volts of electricity when "flexed", a phenomenon which occurs naturally as a result of the downward force of the first and second explosion against the housing. This generates a large and very high-voltage charge which temporarily has no where to go, the crystal becoming its own capacitor. At a given point, the barometric timing device trips, and the charge runs up monofiliment wires attached to bottom half of the outer casing. As the casing is thrown high into the air, the filaments are played out from spools built into the base using technology and parts borrowed from wire-guided surface missiles. When the circuit is closed, these carry the charge to the cloud to produce the final, devastating explosion.

A design variant can apply the final voltage to bare filaments to create a flash-bulb effect which ignites the explosion simultaneously about a vertical column above ground zero. Alternatively, by use of heavier insulated wires stripped bare at a given point, the ignition can be caused to originate at any point between the base and the high-flying lower casing. Finally, the charge could also be applied either from the base itself for traditional blast effects, or from a peripheral position to the cloud (if calculations of cloud size and shape were adequate) for an unusual laterally-focused blast effect. However, this would be a tougher challenge to figure out and control ignition points and timing, especially since variables such as wind patterns and intensity, and air displacements from nearby structures, would need to be considered. Regardless of the focus method employed, because pizo-electric charges are only high in voltage, but not in amperage, the insulated wires do not fuse, and can carry the voltage in tact to its intended destination for ignition.

This bomb design can be subject to great miniaturization. It is possible to build a bomb the size of a soda pop (with simplified design components, such as use of blasting caps) can for use in any precise target application...

The fingerprint of a small-scale METC device applied in an aircraft or other enclosed environment would be miniscule traces of PDTN but no real traditional signature of explosives at all -- no flash damage, no normal residue levels. There would be mostly fire damage of mysterious origin, and since the blast origin point would be the full size of the cloud (most of the cabin), there would seem no blast point or traditional bomb damage at all -- just as if the aircraft "went to pieces". Investigators would be hard pressed to conclude explosives as the means of destruction.

Likewise, the bomb could enjoy great economy of scale as a weapon of mass destruction, concievably on a nuclear scale, but without traditional radiation problems. This would have significant strategic significance as targets could safely be occupied by troops immediately after attack. Seperate studies are under way to deal with the impact of such technology on military planning and foreign policy (fn11).

At this time, construction techniques and quality control requirements remain highly sophisticated and at a level which would defy normal mass production. Unless willing to accept significant performance loss, it requires custom design and construction for any given application. As such, it lends itself to uses perhaps best appreciated by the intelligence apparat. Therfore, its existence should not become general knowledge within other agencies such as DOD (fn12) unless further studies can find such a move advantageous. However, since the unique characteristics of the bomb could conceiveably arrouse great curiosity in aftermath investigations, its use as a covert tool should be undertaken with great restraint and reserved for highly selective application.

Also, if this didn't happen, how did an explosion pull in the perimeter columns?


By decreasing the core's ability to carry load and therby increasing, via the hat truss, the load on the exterior columns. This increased load would induce failure, in the first instance, at the weakest point - the point of aircraft impact.
The core moving downwards would act on the perimeter columns via the floors thus inducing an inward rather than an outward buckling.

But wouldn't the core moving down pull on all the floors equally above the impact? Why only SOME perimeter columns looking just like only SOME floors sagged over the fire?

It would pull on all the floors but it would exhibit firstly in the damaged area around the impact, since these free ends and damaged columns would be the weakest and least able to resist. The floors do not provide any great component of the required buckling load but only provide an impetus to the inward buckling.

What about the sagging floors? I never denied that these existed, I believe in fact it was me who first raised these points on this thread to any extent. Just because the floors sagged does not mean they pulled the columns in. In fact a sagging caused by thermal expansion would have the floors acting outwards on the perimeter columns, not inwards.
Sagging in and of itself would not cause a significant increase in any inward pulling forces on the columns since
the mass does not increase,
the horizontal force component is based on the sine of an angle close to zero,
and the floor mass is insignificant in comparison to the mass of the tower above the storey

Lets look at what NIST really says...

A. Thermal Weakening of the Core:

•The undamaged core columns developed high plastic and creep strains over the duration the building stood, since both temperatures and stresses were high in the core area. The plastic and creep strains exceeded thermal expansion in the core columns.

•The shortening of the core columns (due to plasticity and creep) was resisted by the hat truss which unloaded the core over time and redistributed loads to perimeter walls.

•As a result of the thermal weakening (and subsequent to impact and prior to inward bowing of the South wall), the North and South walls each carried about 10 percent more gravity loads, and the East and West walls each carried about 25 percent more loads. The core carried about 20 percent less gravity loads after thermal weakening.

B. Thermal Weakening of the Floors:

Floors 95 to 99 weakened with increasing temperatures over time on the long-span floors and sagged. The floors sagged first and then contracted due to cooling on the North side; fires reached the South side later, the floors sagged, and the seat connections weakened.

Floor sagging induced inward pull forces on the South wall columns.

•About 20 percent of the connections to the South perimeter wall on floors 97 and 98 failed due to thermal weakening of the vertical supports.

C. Thermal Weakening of the South Wall:

•South wall columns bowed inward as they were subjected to high temperatures and inward pull forces in addition to axial loads.

•Inward bowing of the South wall columns increased with time.


3. Collapse Initiation
•The inward bowing of the South wall induced column instability, which progressed rapidly horizontally across the entire South face.

•The South wall unloaded and tried to redistribute the loads via the hat truss to the thermally weakened core and via the spandrels to the adjacent East and West walls.

•The entire section of the building above the impact zone began tilting as a rigid block (all four faces; not only the bowed and buckled South face) to the South (at least about 8º) as column instability progressed rapidly from the South wall along the adjacent East and West walls.

•The change in potential energy due to downward movement of building mass above the buckled columns exceeded the strain energy that could be absorbed by the structure. Global collapse then ensued.


Are you saying the trusses wouldn't have contracted after cooling, and the contraction wouldn't have pulled the columns in as seen in the photographic evidence? That a bomb could have bowed the much stronger core columns in (Slowly over time) but a cooling, contracting steel truss couldn't create the same effect on the weaker outer columns?

These temps were used in the SUBSECTION analysis to see how a floor section responded to the range of potential heating. The EXTENSIVE fire modeling system was used to determine the temps the INDIVIDUAL trusses and floor sections of the model were subjected to, and for how long, etc etc.

As NIST says a few pages later:

Building on the results of these tests ... (like the one newt posted a reference to).. ANSYS models were constructed ....

The models were subjected to the impact damage and elevated temperatures from the fire dynamics and thermal analysis (presented lated in the same chapter)

Thus just more newt derived BS.

They do however contradict the key part of NIST's initiation sequence, when they say

the core columns cannot pull the exterior columns in via the floors simply as a result of column shortening

They go into detail on page 9 of the link posted.
If the floors could not pull the exterior columns inwards due to these identified thermal effects, then there must be some other cause or mechanism.
So the question which is left unanswered is, what did pull the columns in and thereby cause the collapse?
G

Well the FINAL NIST report answers the question and does not blame the pulling in of the exterior columns simply from the result of the core columns shortening. It is a combination of factors, including the sagging of the floors.

(read the final NIST report, it goes into much more detail)

RealityCheck

Hullo all.

Just catching up with the last few days of posts. Plenty of 'heat' but little 'smoke', hehehe.

(1) About the rubble and fires. Has it occurred to anyone that the 'rubble' mass was effectively 'preheated' by the energies imparted to it by the collapse friction/compression at ground impact? Enough so as to produce a HUGE pile of debris of 'preheated' effectively insulated THERMAL MASS of combustible and non-combustible components, the former of which THEN proceeded to 'burn' to increase/add to the 'preheat' energy/temps already in the pile.

And since I read that the pile was still settling after weeks, then I assume that there were gaps and non-gaps in an INHOMOGENOUS rubble pile where some things could burn and some things couldn't. However, as the fuel in one area burnt off, that would make even MORE gaps for air infiltration as time went on. So it's entirely plausible that the fires while not 'mobile' as in open air, were nevertheless contained and insulated to a very high degree...but still amply aired, and so would burn like in a KILN rather than like an open fire.

And for those who don't understand how that pile could have retained the heat for so long, they should do some research into POTTERY 'batch-FIRING' KILNS whose THERMAL MASS must be allowed to cool for days before they are cool enough to take out the fired product. Imagine what that HUGE pile of THERMAL MASS debris would act like if it was burning fuel inside for so long whose generated heat could NOT escape exactly BECAUSE of its effective insulating blanket as some have described it., so it would go into the HUMONGOUS QUANTITY of 'incombustible THERMAL MASS in the pile. And as we know, a bucket of sand on a campfire will smother it because of the PROPORTIONS of sand to fire surfaces/depths. In that rubble fire, where even the WATER couldn't penetrate effectively for a long time without being vapourised and adding to the 'dissociated-oxygen supply to the fires, how can immobile blanket of dust stop such a HOT and widespread in-pile fire? When we consider the fact that the pile was 'continually settling', and that the snapped 'box' beams open at either ends would produce perfect ADDITIONAL pathways for 'clear air passage from here to there at random in the pile, it is no wonder that the 'pre-heat' from collapse and 'post-heat' from rubble fires produced the necessary temperatures for the period observed. So the 'insulating' effect of the dust blanket actually INCREASED the retention capability of the pile overall. In effect, what we had was a humongous 'kiln' whose THERMAL MASS retained most of the heat energy imparted to it by collapse and fire.

(2) Now about all those exotic explosive formulations/explanations. In fact, such 'hyperbaric' fuel-air explosion as described does NOT depend on 'precise' fuel droplet size and fuel-air proportions. In ALL cases of fuel-air mixes there is a lower threshold for when that mix becomes 'flammable', then at a higher ratio it becomes explosive. Further more, in the scenario previously posited about the fuel down the shafts, WE MUST RECALL THAT IT WAS NOT JUST A FUEL-AIR MIX situation! It was a fuel-air mix THAT WAS BEING DRIVEN AHEAD BY A PREVIOUS FIREBALL/SHOCK FRONT FROM A PRECEDING EXPLOSION AT PLANE IMPACT LEVELS. So the 'ignition/flammability' scenario in that case was NOT solely dependent on the fuel-air ratio itself, BUT ON THE EFFECT OF THE SHOCK HEATING/IGNITION energy provided by the shock/heat of that initial impact explosion which DROVE that fuel-air mix down the shafts. In other words, the situation was pre-primed' by the means of dispersal/ignition in that scenario. Not the 'usual' case, by any means.

(3) Regarding how the columns buckled. I thought it had been made clear some time back that the columns were merely 'biased' inwards sufficiently to PREDISPOSE THEM to buckle preferentially one way rather than the other, depending on when the MAIN loads became intolerable because of that biasing. I also recall myself positing that the initial outward expansion of the steel trusses would have pushed outwards, AND THEN as these distorted members cooled, they again pulled inwards, to effectively BIASE (NOT BEND) those columns sufficiently for the vertical loads to be 'directed' IN sideways where they coincided with that bias. At no time would the floors themselves have done the MAIN DESTRUCTIVE WORK, just the MARGINAL 'BAISING' WORK THAT DETERMINED WHICH WAY THE MAIN DISTORTION WOULD DEVELOP. I leave the rest to plausible consequences, where previously overloaded and damaged columns, no longer 'effectively' supported laterally as required by design, give way under impact/impulse and distortion stresses and loads which can only EXACERBATE once the initial failure point is beyond remedy by any further inherent design countermeasures to what was happening once an obviously 'compromised' structure that was so 'interdependent' on so many other 'now failed' points/elements began to be 'undone', literally.

(4) I hope I'm not going to be accused of being 'Schneibster', or a sock-puppet, or a shill, or a stupid official CT believer etc., merely because I took the trouble to answer certain posts which I felt deserved a response from someone not particularly 'politically partisan' to any party/organisation?

Frankly, as far as I'm concerned, ALL politicians, justice personnel and anyone in a position of power (be it civil, military, scientific or religious etc) is AUTOMATICALLY SUSPECT OF CORRUPTION TO SOME DEGREE unless and until they clearly demonstrate the opposite by word and deed in all things. So please feel free to remove whomever you want from office/power; I don't care. Because one thing will be certain, it won't be long before whoever is put in their place will be just as corrupt/innocent as the last crowd. The only questions as far as I'm concerned are (1) Have you chosen the best of a bad lot, or the worst?.....there is no real alternative when it comes to choosing such monolithic structures/systems, regardless of political leanings; and (2) Have you made your choice based on FACTS or POLITICALLY CONVENIENT LIES....because if the latter, then the 'new' encumbent(s) are compromised FROM THE START and so will sooner or later but INEVITABLY go the same way as those they replaced (the only hope of 'delaying' this inevitable corruption is to be voted in HONESTLY...something which the Republicans apparently don't seem to worry too much about if past electoral antics in your country are any guide, hehehe.

The tower collapsed top down, how would weakening the core in the basement induce implosion from the top?

By decreasing the core's ability to carry load and therby increasing, via the hat truss, the load on the exterior columns.  This increased load would induce failure, in the first instance, at the weakest point - the point of aircraft impact. 
This process is detailed in the recent link posted and referred to in my last post, and also in the NIST report

The core moving downwards would act on the perimeter columns via the floors thus inducing an inward rather than an outward buckling.

Are you suggesting that Lamont and Lane are lying? 
Why would they do this?

One more quick point. I know the 911 sites use Lamont and Lane to bring doubt on the NIST report but it's disingenuous of them to make it sound like they believe there is no way the fires could have been the cause of the collapse. This is being purposefully taken out of context by them.

In fact they say the NIST model is not unlike their own...


This is similar to some of our collapse proposals but no
mention of thermal expansion is made, the floor buckling and
lack of support to the columns seems to be entirely due to
loss in strength and stiffness in their view which we would
consider to be only part of the story.

However we await the publication of the final NIST report
in this regard.

Influence of the hat truss on the
buildlings performance

We have analysed models with and without a hat truss at
the top of a tall-building and found that - a hat truss
significantly improves stability in multiple floor fires.
In the image above, the Hat Truss shows clear redistribution
from outer columns to the core (primarily the outer core
columns). NIST have also observed load transfer via the hat
truss. Such issues could become the basis for future fire related
structural design guidance.

Not one mention of bombs being the only method of collapse or even a question as to fire being the cause. It's clear this is being taken out of context. Creationist do the same deceptive thing. They take competing hypothesis on the mechanisms of evolution to cast doubt on the whole theory of evolution. And just as two hypothesis about what caused us to walk upright only proves there is more than one way we could have evolved this trait, the NIST draft report and "Arup Fire’s presentation regarding tall buildings and the events of 9/11" only prove their is more than one way the towers could have collapsed by fire alone.

"However we await the publication of the final NIST report
in this regard."


Do you have anything from them suggesting a bomb must have caused the collapse? Maybe something AFTER the final report was published?

Also, if they agree with fire being the cause of the collapse, would you agree? If not, are you suggesting that Lamont and Lane are lying?
Why would they do this?
What possible motive would they have?

The question is more valid for you than for me since I'm not saying they're lying.

Hullo all.

Just catching up with the last few days of posts. Plenty of 'heat' but little 'smoke', hehehe.

(1) About the rubble and fires. Has it occurred to anyone that the 'rubble' mass was effectively 'preheated' by the energies imparted to it by the collapse friction/compression at ground impact? Enough so as to produce a HUGE pile of debris of 'preheated' effectively insulated THERMAL MASS of combustible and non-combustible components, the former of which THEN proceeded to 'burn' to increase/add to the 'preheat' energy/temps already in the pile.

And since I read that the pile was still settling after weeks, then I assume that there were gaps and non-gaps in an INHOMOGENOUS rubble pile where some things could burn and some things couldn't. However, as the fuel in one area burnt off, that would make even MORE gaps for air infiltration as time went on. So it's entirely plausible that the fires while not 'mobile' as in open air, were nevertheless contained and insulated to a very high degree...but still amply aired, and so would burn like in a KILN rather than like an open fire.

And for those who don't understand how that pile could have retained the heat for so long, they should do some research into POTTERY 'batch-FIRING' KILNS whose THERMAL MASS must be allowed to cool for days before they are cool enough to take out the fired product. Imagine what that HUGE pile of THERMAL MASS debris would act like if it was burning fuel inside for so long whose generated heat could NOT escape exactly BECAUSE of its effective insulating blanket as some have described it., so it would go into the HUMONGOUS QUANTITY of 'incombustible THERMAL MASS in the pile. And as we know, a bucket of sand on a campfire will smother it because of the PROPORTIONS of sand to fire surfaces/depths. In that rubble fire, where even the WATER couldn't penetrate effectively for a long time without being vapourised and adding to the 'dissociated-oxygen supply to the fires, how can immobile blanket of dust stop such a HOT and widespread in-pile fire? When we consider the fact that the pile was 'continually settling', and that the snapped 'box' beams open at either ends would produce perfect ADDITIONAL pathways for 'clear air passage from here to there at random in the pile, it is no wonder that the 'pre-heat' from collapse and 'post-heat' from rubble fires produced the necessary temperatures for the period observed. So the 'insulating' effect of the dust blanket actually INCREASED the retention capability of the pile overall. In effect, what we had was a humongous 'kiln' whose THERMAL MASS retained most of the heat energy imparted to it by collapse and fire.

(2) Now about all those exotic explosive formulations/explanations. In fact, such 'hyperbaric' fuel-air explosion as described does NOT depend on 'precise' fuel droplet size and fuel-air proportions. In ALL cases of fuel-air mixes there is a lower threshold for when that mix becomes 'flammable', then at a higher ratio it becomes explosive. Further more, in the scenario previously posited about the fuel down the shafts, WE MUST RECALL THAT IT WAS NOT JUST A FUEL-AIR MIX situation! It was a fuel-air mix THAT WAS BEING DRIVEN AHEAD BY A PREVIOUS FIREBALL/SHOCK FRONT FROM A PRECEDING EXPLOSION AT PLANE IMPACT LEVELS. So the 'ignition/flammability' scenario in that case was NOT solely dependent on the fuel-air ratio itself, BUT ON THE EFFECT OF THE SHOCK HEATING/IGNITION energy provided by the shock/heat of that initial impact explosion which DROVE that fuel-air mix down the shafts. In other words, the situation was pre-primed' by the means of dispersal/ignition in that scenario. Not the 'usual' case, by any means.

(3) Regarding how the columns buckled. I thought it had been made clear some time back that the columns were merely 'biased' inwards sufficiently to PREDISPOSE THEM to buckle preferentially one way rather than the other, depending on when the MAIN loads became intolerable because of that biasing. I also recall myself positing that the initial outward expansion of the steel trusses would have pushed outwards, AND THEN as these distorted members cooled, they again pulled inwards, to effectively BIASE (NOT BEND) those columns sufficiently for the vertical loads to be 'directed' IN sideways where they coincided with that bias. At no time would the floors themselves have done the MAIN DESTRUCTIVE WORK, just the MARGINAL 'BAISING' WORK THAT DETERMINED WHICH WAY THE MAIN DISTORTION WOULD DEVELOP. I leave the rest to plausible consequences, where previously overloaded and damaged columns, no longer 'effectively' supported laterally as required by design, give way under impact/impulse and distortion stresses and loads which can only EXACERBATE once the initial failure point is beyond remedy by any further inherent design countermeasures to what was happening once an obviously 'compromised' structure that was so 'interdependent' on so many other 'now failed' points/elements began to be 'undone', literally.

(4) I hope I'm not going to be accused of being 'Schneibster', or a sock-puppet, or a shill, or a stupid official CT believer etc., merely because I took the trouble to answer certain posts which I felt deserved a response from someone not particularly 'politically partisan' to any party/organisation?

Frankly, as far as I'm concerned, ALL politicians, justice personnel and anyone in a position of power (be it civil, military, scientific or religious etc) is AUTOMATICALLY SUSPECT OF CORRUPTION TO SOME DEGREE unless and until they clearly demonstrate the opposite by word and deed in all things. So please feel free to remove whomever you want from office/power; I don't care. Because one thing will be certain, it won't be long before whoever is put in their place will be just as corrupt/innocent as the last crowd. The only questions as far as I'm concerned are (1) Have you chosen the best of a bad lot, or the worst?.....there is no real alternative when it comes to choosing such monolithic structures/systems, regardless of political leanings; and (2) Have you made your choice based on FACTS or POLITICALLY CONVENIENT LIES....because if the latter, then the 'new' encumbent(s) are compromised FROM THE START and so will sooner or later but INEVITABLY go the same way as those they replaced (the only hope of 'delaying' this inevitable corruption is to be voted in HONESTLY...something which the Republicans apparently don't seem to worry too much about if past electoral antics in your country are any guide, hehehe.

Another very informative post.

Would I be correct in saying the planes impact created the largest fuel injector in history? The fuel became atomized as the wings hit the building much like a fuel injector atomizes fuel before combustion. Some fuel burned on impact while some was pushed by the combustion into any place it could fit. Much like the combustion in an engine violently forces a piston down.

If you run a car rich you it wont burn all the fuel. You can smell the gas coming from the tale pipe. Nothing says all fuel has to burn under ANY condition as long as some has been ignited. Something the CTers seem to miss.

Arthur first tells us there is no evidence for yellow-hot temps (after he had seen a pic of it), then tries to convince us yellow-hot temps are within normal fire temperatures. 1000 C is a normal office fire temp? PROVE IT. Why do you disagree with the official government report, which says the steel in the WTC probably didn't even reach a temp over 650 C??? Where did you get this 1000 C story?

Lets see, in answer to LSoS's latest dump

There ARE no precedents because there has never been this large of a burning office debris, steel and aluminum pile in history, you know ANYTHING REMOTELY SIMILAR TO THE PILE BURNING AT THE WTC SITE.

However, large debris piles do catch on fire and are hard to put out.

http://www.bsa.ca.gov/pdfs/reports/2003-113.pdf

(See page 20 for picture of debris pile that took 30 days to put the fire out)

The fire dept guy describes it as a BRIGHT RED hot oven.

Thermite is not RED HOT, its WHITE HOT. The Fire guy wouldn't have mistaken a THERMITE FIRE for an OFFICE MATERIAL FIRE.

He catagorized it as 1,500 F, which is BRIGHT RED.

Which is ~750 to 800 C

Which is within the range of debris pile fires.

As to 1,000 C temps in office fires:

Per NIST final report (Sec 6.12.3 - pg 132)

It was expected, and soon confirmed that the fires could generate temperatures up to 1,100 d C.

Furthermore, the temp of steel in the hour the the towers burned is not a constraining factor on the temp of steel within the burning pile.

The only liar is you as I don't work for a "govt connected" entity.

Which just reinforces your "Sack O' Shiit" status.

Hat truss theory adds to WTC collapse controversy

Controversy still surrounds the exact collapse mechanism of the Twin Towers, despite three years of detailed investigation by the National Institute for Science &Technology (NIST) team.

Some engineers believe the collapse was influenced by factors other than the fires caused by buring aviation fuel which weakened vital structural steel elements.

And they have accused NIST of repeatedly changing its explanation of the collapse mechanism.

“In this latest version, the ‘hat trusses’ on top of the towers play a crucial role in the redistribution of stresses after the impact,” one leading US structural engineer told NCE in New York. “In earlier versions they are hardly mentioned.” (NCE 21 October 2004).

The trusses were originally designed to carry loads from TV towers on the roofs – but only WTC 1 ever had such a tower. NIST now believes the trusses helped the upper storeys of the towers to stand up after the aircraft impacts.


Consultant Arup has frequently criticised NIST’s analysis of the collapse mechanism.

Last week Arup went on the attack again. In a statement, Arup associate Dr Barbara Lane said: “We consider thermal expansion in fire to be a leading factor in a collapse.

“This does not seem to have been addressed in NIST’s recommendations, but we hope it will become part of the ongoing discussions going forward.”

"Controversy"

"accuse NIST"

"frequently criticised"

"attack"


These words do NOT imply that All Structural Engineers are completely in agreement with NIST's findings.

Now the obvious 'come-back' will be, "yeah, but Arup (and other engineers DO NOT say the buildings were demo-d either)".

True enough, but... beyond the point.

The original contention being spread by the government disinformationists here (and of course ALL threads related to 9/11 events), is that...

"NOT ONE structural engineer disagrees with the NIST findings"...

Or ... in other words

"NIST has written a 'biblical treatise' on why & how the towers collapsed, which is completely unchallenged by any respectable engineers."

These 'quotes' are untrue... and are simple 'appeals to authority' in attempts to bolster their own conspiracy theory.

Some comments made by David M. Scott (of Arup) in a paper presented to The Mulithazards Mitigation Council

{related to the relevance of furnace testings to determine fire ratings}...

QUOTE

Passive fire protection requirements are formulated based on testing of assemblies in the standard furnace test as per ASTM E119 (ASTM 2000). Traditionally it has been assumed the standard furnace test replicates real structural response to fire conditions. Therefore if a single element or assembly, with or without fire protection, survives a 1 hour or 2 hour furnace test, it has an equivalent ability in a real fire to survive for 1 hour or 2 hours respectively.


However the standard furnace test has always been criticized due to the well-referenced fact that the heating regime does not represent most real fires. Real fires are a function of fuel load, compartment dimensions, thermal properties of the compartment boundaries, and the quantity of unprotected openings that allow ventilation in a post flashover fire. They can therefore be more severe or less severe than the standard furnace.

(Pg 3)

However more importantly the standard furnace test does not assess real structural response in fire conditions because single elements / assemblies are tested in a furnace even though they form component parts of complex 3 dimensional frames in real buildings.

Performance-based design approaches assess overall structural response to real fires. Real fires are used as a basis of design, and frame responses can be determined using simple analytical techniques or Finite Element analyses.

You look at yellow and say you see red. Yellow means 1000-1080 C. You said before that the glowing metal might be lead or aluminum, didn't you? You didn't know that those metals aren't solid at those temps, but you spoke with such conviction. You were SURE of what you were saying. Were you correct, or were you wrong? You tried, and failed, to convince people here that it might have been lead or aluminum that glowed yellow-hot.


"Furthermore, the temp of steel in the hour the the towers burned is not a constraining factor on the temp of steel within the burning pile."

Hahaha, no; as long as the steel got HOTTER after the towers burned. No problem with your logic at all, no sir.

WEEKS after 9/11, it was yellow-hot. Which means it was HOTTER on 9/11. WAY beyond the temps reached by office building contents burning, or jet fuel.


Read this: "Of the more than 170 areas examined on 16 perimeter column panels, only three columns had evidence that the steel reached temperatures above 250ºC… Only two core column specimens had sufficient paint remaining to make such an analysis, and their temperatures did not reach 250 ºC. ... Using metallographic analysis, NIST determined that there was no evidence that any of the samples had reached temperatures above 600 ºC. (NIST, 2005, pp. 176-177; emphasis added.) "

A fuel-air mix AHEAD of a PRECEDING explosion? How does THAT happen?


Are you saying cars can't run rich? Because it's the same principle. Unspent fuel is AHEAD of the explosion in the cylinder head. It's forced out the valve into the exhaust pipe through compression. Sometimes the fuel even explodes in the exhaust pipe. This isn't rocket science. I knew about this when I was a kid tinkering with cars.

Your attack of Arthur only underscores your vacuous reply. Arthur didn't write that post. RC did.

I never said anything about explosives causing the yellow-hot temps, nor anything about "explosions in the basement blowing up the top of a building". You have me confused with someone else, apparently.

Now can you answer my questions? When have any of the things you guess about ever happened before? Answers please, not just diversions and attacks. You're making WILD guesses that don't make the least bit of sense.

You're saying fuel ignited ("exploded,", as you say) first, then unburned fuel BEHIND the explosion was driven down to the basement. By the explosion, which happened first. This is babble.

PRECEDING means before. You know that, right?

Conspiracy sites like to bring up molten steel found 6 weeks after the buildings fell to suggest a bomb must have created the effect. The explanation doesn't go into the amount of explosive material needed because it would be an absurd amount. There is another explanation which is more plausible.

Despite repeated calculations showing that the energy released simply from the kinetic collapse is on the close order of a small nuclear weapon, without even mentioning the energy contents of the millions of tons of paper, wood, plastic, etc. that were on the floors and a large percentage of which would be in the rubble pile and heated to ignition point by the heat from the kinetic energy dissipated by the collapse.

My best estimate at 13 psf by 35,000 sf/floor by 110 floors by about 30% combustibles, 60% metal and other non-combustible items, by the energy content of common garbage, gives a lot more energy than the energy of the collapse. The insulation provided in that debris pile was apparently pretty good, and that’s not surprising. Rock and concrete really are bad heat conductors, air isn’t much better, and steel while capable isn’t all that good, as you can tell from the fact that the jaws of the shovel aren’t melting. Ever hear of “rock wool?” It’s insulation; look it up. You’ll get the idea pretty quick.

There’s two more factors I’ll throw in: first, a certain amount of the office materials didn’t make it into the debris pile, perhaps as much as 10% of it just got scattered all over lower Manhattan island. Second, a few floors worth had already burned. So when the time comes, I’ll take three floors out, and then another 10%. You’ll be surprised, I think, at how much energy there is involved.

This, by the way, is a place where Jim Hoffman makes a serious mistake; in his paper on the dust cloud, he fails to note that he has to ADD THE HEAT BACK IN when he’s totaling things up at the end. This is a violation of conservation of energy, the First Law of Thermodynamics (and a foundational law of physics). The energy dissipated during the fall is about 250 or 300 GJ, and the leftover energy at impact is about 600 GJ. So it’s about a quarter kiloton of TNT for the North tower and about a fifth of a kiloton for the South tower; that’s still a hell of a lot of energy, more than sufficient to liquefy a pretty healthy chunk of steel, and it doesn’t change the fact that there’s a lot more energy in the office contents.

You should be aware that anytime you do mechanical work, the energy you do it with doesn’t just “go away” or “get used up.” Energy that does work gets dissipated, and when that happens, it turns to heat. This is a well known fact of physics, specifically thermodynamics, that was proven early (or maybe it was late? no, I’m pretty sure it was EARLY) in the nineteenth century by the gentleman for whom the SI unit of energy is named, James Prescott Joule. Go look him up on Wikipedia, or elsewhere if you’re a newbie and believe what you read in the newspapers about Wikipedia. He did this experiment where he stirred water in buckets and showed it got hotter.

This, by the way, is a place where Jim Hoffman makes a serious mistake; in his paper on the dust cloud, he fails to note that he has to ADD THE HEAT BACK IN when he’s totaling things up at the end. This is a violation of conservation of energy, the First Law of Thermodynamics (and a foundational law of physics).



What distance do you drop the load from? The floor of initial collapse: 79 for the South tower, 97 for the North. It’s a variable in the program, you can change it for yourself and run it yourself, it’s a perl. Interestingly, going from a 39-story to a 13-story falling section doesn’t make a great deal of difference in the energy, and makes even less difference in the energy that’s left over when the building hits the ground.

A falling building is not like a bomb or a laser beam. But it makes heat all the same- just like all work makes heat. Feel the bottom of the bicycle pump after you’ve pumped the tire up. Where does that heat come from? Same place as this does.

While a 600GJ bomb would take out ten blocks in any direction, the WTC collapse obviously did not. While that’s true, you need to know that conservation of energy says that energy NEVER disappears. It ALWAYS winds up SOMEWHERE, and if this is energy capable of knocking buildings over for many blocks in all directions, and it didn’t knock them over, then where did it go and what did it do? Answer: it went into the rubble pile, and it melted and burned stuff in there.

There was energy spent “pancaking” or “snapping supports” if you believe those theories (I do not). Whether it was explosives or whether it was sheer mass and momentum that snapped them (and I have excellent reason to believe it was nothing but mass- you’ll see shortly), it STILL made heat, and that heat STILL went into the debris pile at the bottom. Heat is energy and energy NEVER just “goes away.”

All the collapse theories say that the weight of the top of the building is what caused the collapse… well that is HALF true. It was also pushing UP WITH EQUAL FORCE. This force was largely transmitted into the ground during the collapse, not the rubble afterwards. The STATIC FORCE of the building pushes down and the ground pushes up, when the DYNAMIC FORCE of the collapse occurs, it is local to whatever is moving; this is because it’s the MOTION that causes the DYNAMIC force, and that force is (and must be, to collapse the building) many times the static forces of the building just standing there.

Now, for the program:

**BEGIN PROGRAM**

#!/usr/bin/perl
$m = 4285500; # mass of one floor (kg)
$mt = 0; # mass of falling section
$fc = 39; # floor count of falling section (39 floors for 2 WTC)
$v1 = 0; # beginning velocity for the current step
$v2 = 0; # velocity at impact
$v3 = 0; # ending velocity for prior step
$p = 0; # current momentum
$ke1 = 0; # kinetic energy at impact
$ke2 = 0; # kinetic energy after impact
$de = 0; # total energy dissipated so far
$a = 9.80665; # acceleration of gravity (constant)
$t = 0; # cumulative time taken
$t1 = 0; # time taken for this step
$d = 3.8; # distance between floors (418m/110 stories)
$mt = $fc*$m; # initialize mass of falling section
$rfc = 110 – $fc;# initialize remaining floor count of uncollapsed floors
while($rfc > 0) {
$v1 = $v3; # starting velocity is ending for last step
$v2 = (($v1*2)+((2$a)*$d))**0.5; # impact velocity for this step by formula
print(“Impact velocity for story ”, $rfc, ” was ”, $v2, “n”);
$p = $mt*$v2; # momentum at impact
print(“Impulse delivered for story ”, $rfc, ” was ”, $p, “n”);
$ke1 = ($mt*($v2**2))/2; # kinetic energy at impact
print(“Impact kinetic energy for story ”, $rfc, ” was ”, $ke1, “n”);
$fc++; # increment falling floor count
$mt = $fc*$m; # update mass of falling section
$v3 = $p/$mt; # new velocity
print(“Velocity after impact for story ”, $rfc, ” was ”, $v3, “n”);
$ke2 = ($mt*($v3**2))/2; # kinetic energy after impact
print(“Remaining kinetic energy for story ”, $rfc, ” was ”, $ke2, “n”);
$de += $ke1 – $ke2; # add dissipated kinetic energy to total
print(“The kinetic energy dissipated for story ”, $rfc, ” was ”, $ke1 – $ke2, ”
n”);
$t1 = $d/(($v2 + $v1)/2); # time for this step by formula
print(“The time spent collapsing story ”, $rfc, ” was ”, $t1, “n”);
$t += $t1; # add step time to running total
$rfc—; # decrement remaining floor count
}
print(“The total time was ”, $t, “n”);
print(“The total energy dissipated during the collapse was ”, $de, “n”);
print(“The remaining kinetic energy at the end of the collapse was ”, $ke2, “n”
);

**END PROGRAM**

It’s a perl, you can download perl for just about anything from www.perl.org or somewhere they point. If you’re going to get involved in CS, somewhere you’re going to encounter perl, and now’s as good a time to learn it as any. I highly recommend the O’Reilly Press perl book which happens to be by the inventors of the language. Just so you can muddle your way through and derive the equations from the code above, * is multiplication, ** is raising to a power (and don’t forget that a fractional power is a root; so **0.5 is the square-root operation). The rest of the symbols are obvious, and the parentheses work the same way as they do in standard math notation. You should be aware that the single = in most languages simply ASSIGNS the value of what’s on the right to the thing on the left; usually, you’re required to put a single variable on the left of an =. The double == TESTS whether one value is equal to another, returning 1 or TRUE if it is, and 0 or FALSE if it is not.

Though these quotes are subjective interpretations, taken out of context or based on PRELIMINARY NIST reports, Foxx has a point. I have asked for people to provide ANY evidence that NIST has it wrong.

I didn't mean have ANYTHING wrong!

I fully expect that there will be engineers that will be at odds with SOME aspects of NIST's extensive effort.

What I should have said is for people to provide evidence that NIST's conclusions that the plane crash followed by building fires resulted in LOCAL collapse and that the local collapse lead to a global collapse, were incorrect.

NONE of these engineers state that they disagree with this FUNDAMENTAL conclusion.

If you go back to the last ARUP document in a previous post you will find that THEY identified the impact of the HAT TRUSS on transferring the loads to the center. They claim to have done so before it was identified by the NIST model. But in the END they both agreed on how the Hat Truss performed in the fire.

In fact, from the SAME link that Foxx provided:

Virtually all conclusions in NIST’s official report into the collapse of the World Trade Center towers were reached in the UK three years ago, engineers said this week.

A major report Safety in tall buildings was published in July 2002, just 10 months after the towers collapsed (NCE 11 July 2002) by an Institution of Structural Engineers-led panel which included ICE senior vice president and Jacobs Babtie director Gordon Masterton.

Its recommendations are similar to those published by NIST. These included calls for buildings to be designed to survive complete burn out, include “robust, resilient and durable passive fire protection” and allow large-scale evacuation. It also called for regular independent audits of fire protection systems.

“The interesting thing is that the more you read the more it looks similar to what we did in the UK after 9/11,” said Masterton.

“Of the 30 recommendations 24 are identical messages to those contained in our report,” he said.


Also from the Foxx reference:

Fire protection demands threaten to stifle design innovation

Engineers fear their efforts to produce innovative tall building designs will be stifled following publication of last week’s comprehensive report into the World Trade Center tower collapses in 2001.

In Britain, structural engineers face greater pressure to justify cutting edge tall building designs.

And in the US, recommendations in last week’s NIST report on the 9/11 attacks are also expected to stop in their tracks, efforts to push the boundaries of tall building design.

The NIST report makes 30 recommendations, many relating to fire protection improvements.

One calls for US-wide adoption of the “structural frame” approach to fire resistance ratings, where all structural members must carry the same fire rating. This is expected to make American designs more conservative.


==> Now this was the PERFECT opportunity for one of these UK NIST "attackers" to say: "Why the heck are we worrying about FIRE protection, it was the Friggin BOMBS that brought down the WTC towers".

Good point. They would have been pushing for bomb resistant engineering. What they are pushing for are buildings designed from the start with fire resistance. Not just spray on fire proofing after the fact.

Computer Fogie,

Can you NOT read? I posted the reference for the fire temps that office material can reach?

QUOTE (adoucette+)
As to 1,000 C temps in office fires:

Per NIST final report (Sec 6.12.3 - pg 132)

It was expected, and soon confirmed that the fires could generate temperatures up to 1,100 d C.


I pointed out that the temp of steel in the hour the the towers burned is not a constraining factor on the temp of steel within the burning pile.

Why do you think that Steel temps COULDN'T rise in the rubble pile?

In the BURNING BUILDING, the Steel temps are pretty much limited by the amount of material on one or two floors.

In the PILE though, the steel could be heated for WEEKS as there was almost no limit to amount of burnable material.

So if OFFICE FIRES can reach ~1,100 C, then it stands to reason that given time, steel in a burning pile of office rubble can also reach a temp of ~1,000 C.

QUOTE (LSoS+)
You said before that the glowing metal might be lead or aluminum, didn't you? You didn't know that those metals aren't solid at those temps, but you spoke with such conviction. You were SURE of what you were saying. Were you correct, or were you wrong? You tried, and failed, to convince people here that it might have been lead or aluminum that glowed yellow-hot.



And, if you look back at my posts, I said that if people actually SAW flowing streams of METAL that they were probably lead or aluminum. I have never said the piece being plucked from the rubble pile wasn't STEEL.

Which is why you remain a Lying Sack o Shiit.

Not explosives, as I've said. I never said explosives caused the yellow-hot metal.

Thermite, as has been used in the construction industry for decades to melt steel. It doesn't burn yellow-hot, it burns WAY hotter, around 2500 C. Hot enough to explain why there was yellow-hot metal in the rubble, weeks after 9/11.

Good point. They would have been pushing for bomb resistant engineering. What they are pushing for are buildings designed from the start with fire resistance. Not just spray on fire proofing after the fact.


Engineers from various disciplines are analysing the reports from NIST.

Some are from the structural engineering viewpoint, others from the fire-engineering viewpoint, others from a materials viewpoint, and still others from the physics viewpoint.

The structural & fire engineers are looking at the 'collapse mechanism' merely from the viewpoint of events leading UP TO the 'initiation' of collapse.

We ALL know that 'collapse' is possible-to-generate from the leading events... (That is 'partial collapse')

What NO ONE in these fields is addressing are the actual Collapse propagation effects.

The simple statement is made that 'once collapse is initiated'... (END OF STORY)... it inevitably leads to 'exactly' what was seen at WTC is without merit.

It IS NOT & CAN NOT be addressed from either a fire or structural engineering discipline alone, because the speed, verticallity, symmetry, explosiveness, and continued underground infernos (reaching temperatures higher that observed in normal building fires - even those which have added accelerants)...are outside of the realms of normal fire & structural engineering.

What is so hard to understand about that?

What !!!? You didn't like my alternative thermobaric bomb theory?

No, because it's only a fantasy without a shred of evidence to back it up. You have no scientific theory that uses evidence and is falsifiable.

We SAW the plane

We SAW the fireball

Eye Witnesses said the smell of jet fuel was heavy in the air.

No bomb was seen

No bomb parts were recovered

Hence one has evidence and the other doesn't. That's why I don't like it.

How much thermite would you need?

Has this ever happened before? A reliable source of evidence please...

So Fogie,

What you are claiming is that they used Thermite to cut enough of the massive columns in the basement of the WTC towers to cause it to collapse.

And that the resulting melted steel is what we see being plucked from the debris pile (after its cooled down a tad).

Correct?

That doesn't explain why Jones is taking that quote out of context. He doesn't mention that Lamont and Lane agree with most of the NIST DRAFT report nor does he say they agree with fire as the cause of the collapse. He purposefully uses the text which helps his case while leaving the parts which destroys his case out.

Down right dishonest. Crap a politician or con man would do.

This is one of the CT's stock answers for this:

http://physics911.net/thermite.htm

Happened before?

Depends on who you ask, if you ask the CT'ers there is no end to the "things" that have happened but us normal people are too dumb to know.

That's the ultimate irony, they THINK they are so SMART yet their posts show how incredibly MORONIC they can be.
