How do they make Nanoaluminum:
PLASMA PROCESS FOR PARTICLES
COULD FUEL EXPLOSIVE GROWTH
May 6, 2002 – With a $6.4 million investment announced Friday and a promising production process in its IP arsenal, Nanotechnologies Inc. of Austin, Texas, plans to make nanopowders of very precise and consistent particle sizes.
Nanoaluminum, one of the particles the company can produce with in its plasma reactor, is an excellent ingredient in "energetic materials" such as solid-fuel rocket propellant or high-tech explosives like the new generation of "thermobaric" bombs used in Afghanistan to destroy caves or underground facilities.
The company's plasma process is its trade secret weapon. In a few thousandths of a second, a reactor zaps a rod of solid material with a massive pulse of electrical energy, heating it to 50,000 degrees Celsius.
In another blink of the eye, the gas of vaporized material cools. This rapid cooling, or quenching, is how the company controls the size of the resulting nanoparticles and ensures that the most particles are close to the desired dimensions.
How the company collects the nanoparticles, which it can make in a range from 10 to 100 nanometers, is a trade secret.
http://www.smalltimes.com/document_display...84&keyword=hamiA good example of the overpressure of Thermobarics VS normal high explosive:
Thermobarics aren't just a more powerful version of normal high explosive. The term encompasses a range of different types of warhead from fuel-air explosives, which release a cloud of flammable material and detonate it, to metallized explosives whose expanding fireball takes in oxygen from the air. What they have in common is that they produce blast which has a lower overpressure but a longer duration than normal condensed explosives. In effect it is a shove rather than a punch: a thermobaric explosion does not smash a hole in a wall, it pushes the wall over. An instantaneous explosive overpressure of 50 psi [pounds per square inch] is needed to kill. But one sustained for a fraction of a second at 10 psi is also lethal. That’s how thermobarics kill.
http://www.defensetech.org/archives/cat_am..._munitions.htmlHi reasonwhy. Thanks for that post - finally some intelligent input.
For those of us who are 'aware' that the buildings could NOT have 'Just-Fallen-Down' according to the physics of 'progressive-collapse' the questions presented by gravity-driven collapse supporters are for the most part straw man nonsense and appeals to disbelief that advanced weaponry is available. Usually detractors make wails of incredulity and references to science fiction as 'evidence' that such devices do exist in the arsenals of dark cover miltary-industrial organizations.
They seem to feel that if it is not shown on the nightly news, that the absence of that
evidence IS THERFORE
evidence that advanced weaponry such as we have as never heard of DOES NOT EXIST. In my opinion, this is a true fairy tale belief.
I would admit that the detractors DO have a semi-valid point that (as yet) we can not offer substantive
proof that such weaponry was utilized in the destruction of the towers, nevertheless neither can they 'prove' through science or physics that such advanced weaponry was NOT used.
All we have to go on factually is that it is impossible due to the engineering principles of
resistance that the buildings could have collapsed as quickly, and symmetrically as they did. Gordon has addressed this more than adequately (to those of us who have any understanding of engineering principles). That is a fact... regardless of the 100's of pages in this thread devoted to 'debunking'
free-fall or
close to free-fall aspects.
It's not quite scientific or realistic to state simply that free-fall speed is X... so,
IF the buildings fell ANY slower, that if they were falling through thin air, THEN that 'proves' they fell through "progressive or gravity-driven collapse".
Pure bunk.
Anyone who can not fathom that simple fact shouldn't be wasting their time here.
Even IF one were to accept an extended number such as 20 seconds for the collapse, it would mean that the buildings were disintegrating at a speed of 5 floors per second. If we accept that the floors were 12' high... that means that the buildings were disintegrating at a speed of 60 feet of
structurally sound building per second.
Well, no one really needs an engineering degree to tell that
that is just an impossibility according to physics... a five story building disintegrating to the ground in ONE SECOND - absolutely impossible without the input of added energy.
Many of us are already well beyond understanding that simple fact and now have progressed to trying to determine a plausible source of energy input which CAN account for such an engineering phenomenom. Jet-fuel and piddly fires can't account for this, as has been proven over and over on this thread.
Anyway getting to that link you provided to the thermobarics... very plausible in my opinion. I followed some of the links from your original link and found that one of the typical effects on humans is damage to lung tissue. It doesn't take much research to find that many of the initial burn patients from the ground floors suffered just that tell-tale sign.
The link to Janes Intelligence Group turned up a very interesting video of the damage a simple Russian shoulder fired thermobaric weapon could do when employed against a building...
the RPO-A Schmel explosion... shows great similarity to the lateral (and upwards trajectories) of debris ejected from the WTC towers from such a blast (not to mention the centre column of smoke lingering AFTER the explosion)...
http://warfare.ru/?catid=278&linkid=1847&video=trueAgain, thanks for the link and input. Most of us (who are here to discuss the scientific aspects of these 'collapses'), appreciate the efforts put in to contribute valid information.
100 pages of discussing Larrys 'pull-it' statement is just strawman stuff that's just a waste of bandwidth and goes no-where.
Cheers... (mate)

Hi Foxx! I was just checking to see if hereward answered my question regarding his non de plume, when I noticed both your "Cheers....(mate)" and newton's allusion to realitycheck (Hi newt! Missing me already?). I DID warn you all that I would respond if addressed/alluded to, didn't I? So don't blame me if I was forced to post this, hehehe.
Foxx, like Hoffman is now doing, I suggest you TOO re-do your calculations. This time, try to use the ACCELERATION of gravity to calculate what SPEED/MOMENTUM/IMPULSE those 5-floors would have after ACCELERATING through 110 story height....and therefore what fraction-of-second TIME they would only need to rip through the lower/lowest 5-floor sections by that time. Your 'selected average' for the START of a collapse of 5 floors 'only' is invalid unless you also take into account the FINISHING rate after 110 stories and THEN 'average out'. Either you knew that before you posted, or you know nothing of real physics and are just a simplistic thinker....perfect for being a CTer and very little else.
By the way, the collapse was basically INTERNAL because of the floors pancaking WITHIN the outer tube....so the outer tube rate of destruction 'tracks' slightly behind the 'internal pancaking' rate of collapse destruction....so it's not strictly true to say the outer tube 'collapsed', but that the outer tube was 'destroyed and expelled piecemeal' as the side-pressure of the internal pancaking rubble 'plug' broke it off progressively. In short, the outer walls didn't 'fall' from the 'pristine state; they only fell as 'pieces' already destroyed by the INTERNAL fall rate of the pancaking floors and eventually disintegrating top section & hat truss.
Cheers, mate! Heh! and Ciao to boot...plus hehehe.

1) The thread was started by a guy (Andrew Johnson) who has since disappeared, even his name is gone ... don't know why. I found the thread interesting in the beginning because Andrew's posts were courteous and he kept the discussion relentlessly "on topic" without being rude.
I am glad to see mention of Andrew Johnson's original post. Andrew brought up the rate of the collapse as a major problem that could not be accounted for by the official version of the collapses. A great deal of the early controversy on this thread centered on whether the collapses were free fall, faster than free fall, or near free fall. There was a lot of quibbling about a few seconds here or there. For my part, I still believe that the speed of the collapse has not been adequately explained by the official hypothesis (OH). Actual simulation of the collapse is apparently a place where NIST and the supporters of the OH do not dare to go. Fortunately, that is not the case with everyone. One of the papers presented by the OHers in support of gravitation collapse is that of Lu and Jiang:
http://www.luxinzheng.net/publications/english_WTC.htmI brought this up a couple of days ago. It did not get any attention, but I still believe it is significant. Lu-Jiang present what is the only FEM simulation of the collapse of the towers. The authors are only able to induce a complete collapse in an extreme case when they lower the fracture plastic strain of the steel to 0.5%. When this value is at 1% there is only a partial collapse that is arrested 100m below the damaged areas. At 5% there is only a localized collapse near the plane impact area. "gordon" has shown from Bazant-Zhou and Greening that a strain of at least 3% is expected. Further, in the Lu-Jiang case of 0.5%, the simulated collapse times are much greater than the actual times. It is unfortunate that they do no mention the times in their paper, however they did provide these values when I inquired. The collapse times they found are:
North Tower: 1:53
South Tower: 1:32
For the North Tower, that is about a factor of 7 greater than the actual time. I believe this begins to confirm the instincts and intuition of many people who have returned to review the WTC collapses after the initial "shock and awe" of the event have worn off. Lest I be accused of covering anything up, let's be clear that Lu-Jiang support the OH in their paper. However, it is telling that they did not report the estimated collapse times, and I cannot see how these results can be offered in support of the OH. I can only guess at how OHers would react to this. If indeed they are done on this thread maybe we won't find out, but I will be interested to see how they try to explain it away. This is, after all, a peer reviewed paper, so by their many claims in that regard it should not be easy to dismiss.
After over 500 pages of circular argument and cheap insults, your post was so refreshing to read. In addition I agree with you and think Andrew Johnsons original post is the direction this thread needs to go in......

OK, firstly, its clear that FOXX is giving us a rough average figure - agreed. The figure is based on a "generous" collapse time of 20 secs. In reality the rate of destruction would have been slower than 5 floors per sec in the early phase of the collapse, and faster than 5 floors per sec towards the end of the collapse.
Is this a correct representation of what you are saying? (I want to be sure I have not misunderstood your argument ).

Hello Chris. Since I'm still here for the day, I would just point out that:-
(1) It was your fellow CTer FOXX who FIRST accused YOU of being a disinformation agent for the govt., not the non-Cter 'side'.
(2) It was your fellow CTer FOXX who early on pointed out to ME that the core contained heavy columns where you say they were NOT.
(3) It was your fellow CTer FOXX who pointed out to ME early on that there was NO re-inforced concrete core (other than floors) where you say there WAS.
So perhaps, now that many non-CTers feel they have done enough "Basic Physics' to satisfy Andrew Johnson's stated aims for starting this thread, you might like to take up your concerns with your fellow CTer FOXX....who seems to contradict you in every way.
Go on, ask Foxx to answer your questions about the core columns; and about the re-inforced concrete core; and what he thinks NOW of your motives and your posts here.
To take a leaf out of newton's book: "I dare you". Cheers! And good luck getting any sense/truth out of FOXX, Chris.....you'll need it! Adios, amigo!

It is unfortunate that they do no mention the times in their paper, however they did provide these values when I inquired. The collapse times they found are:
North Tower: 1:53
South Tower: 1:32
For the North Tower, that is about a factor of 7 greater than the actual time. I believe this begins to confirm the instincts and intuition of many people who have returned to review the WTC collapses after the initial "shock and awe" of the event have worn off. Lest I be accused of covering anything up, let's be clear that Lu-Jiang support the OH in their paper. However, it is telling that they did not report the estimated collapse times, and I cannot see how these results can be offered in support of the OH. I can only guess at how OHers would react to this. If indeed they are done on this thread maybe we won't find out, but I will be interested to see how they try to explain it away. This is, after all, a peer reviewed paper, so by their many claims in that regard it should not be easy to dismiss.
Great find!

Practice debunkery-by-association. Lump together all phenomena popularly deemed paranormal and suggest that their proponents and researchers speak with a single voice. In this way you can indiscriminately drag material across disciplinary lines or from one case to another to support your views as needed. For example, if a claim having some superficial similarity to the one at hand has been (or is popularly assumed to have been) exposed as fraudulent, cite it as if it were an appropriate example. Then put on a gloating smile, lean back in your armchair and just say "I rest my case."
Remember that most people do not have sufficient time or expertise for careful discrimination, and tend to accept or reject the whole of an unfamiliar situation. So discredit the whole story by attempting to discredit *part* of the story. Here's how: a) take one element of a case completely out of context;

find something prosaic that hypothetically could explain it; c) declare that therefore that one element has been explained; d) call a press conference and announce to the world that the entire case has been explained!
-------------
A rational person participating as one interested in the truth will evaluate that chain of evidence and conclude either that the links are solid and conclusive, that one or more links are weak and need further development before conclusion can be arrived at, or that one or more links can be broken, usually invalidating (but not necessarily so, if parallel links already exist or can be found, or if a particular link was merely supportive, but not in itself key to) the argument. The game is played by raising issues which either strengthen or weaken (preferably to the point of breaking) these links. It is the job of a disinfo artist to interfere with these evaluations... to at least make people think the links are weak or broken when, in truth, they are not... or to propose alternative solutions leading away from the truth. Often, by simply impeding and slowing down the process through disinformation tactics, a level of victory is assured because apathy increases with time and rhetoric.

911 EYEWITNESS SHOWS AT INTERNATIONAL PRESS CONFERENCEIs the American Press still Free?This was the title of a controversial presentation at a prestigious press club in Tokyo, Japan, Tuesday, March 14. The New York Times Tokyo Bureau Chief, Jim Brooks, said that he couldn’t attend an official press function about 9/11 or he would be fired. Coincidentally, the Reuters Bureau chief, Daniel Sloan, was also a strong opponent to the event being held, but he and Brooks were voted down by international members and the event was able to go ahead.
911Eyewitness was screened during dinner for 50 international journalists at the Tokyo, Foreign Correspondents Club of Japan and received tremendous applause.
Was this meeting the reason that the 911 Eyewitness site was hacked? Did this screening for influential journalists trigger a retaliatory attack on the news website?
Are the evildoers getting worried about the scientific analysis of controlled demolition presented in 911Eyewitness?
Could this line of inquiry be the weak link that they have no debunking defense against?
Long-standing FCCJ member Benjamin Fulford, former Tokyo Bureau Chief for Forbes Magazine, chaired the discussion about 9/11 evidence. He talked about his own personal epiphany after researching the evidence available on the net. He challenged the international press to do their own investigations to determine whether the bloggers have scooped the mainstream press on the true story behind the terrorism of Sept. 11, 2001.
Those in attendance were virtually unanimous in agreement that controlled demolition brought down the towers after watching 911Eyewitness.
The lone vocal critic who labeled 911Eyewitness analysis featuring Newton’s Laws of Science as “propaganda” was quickly silenced by additional testimony from ex-MI5 agent David Shayler, stating 9/11 was an inside job, streaming from the internet on Google’s video site.
The evening was a resounding success for 9/11 truth.
Japan is currently buzzing with numerous magazine articles on 9/11 and may prove to be a key ally in the fight for truth. Stay tuned for more.
Note: This morning we got the site operational again after it was brought down by hackers on the 14th. Coincidence that it was not available to the Conference?911Eyewitness

The fact that there were 47 massive interior core columns is incontestable.
The ONE photo Christophera posts as 'evidence' to his theory is unsupportable when compared to historical evidence.
Notice that the gravity-driven collapse supporters 'attacks' against him are a sham.
Check out 'Democratic Underground'
Sorry... I have to call a 'spade' a 'spade'.

Break it down frame by frame (i will do the same)
Feel free to link to PHOTOS of damage, and diagrams showing the 24 steel beam core columns and 57 perimeter columns.
I don't feel we should involve the firemens quotes because they are often dismissed when brought up involving the WTC 1,2 collapse events. Rudy Gulliani was in WTC 7 when the first tower fell and recieved a phone call to 'get out it was going to collapse'
Why did he recieve warning and not the firefighters staging in the bottom of both towers?

March 16, 2006
WASHINGTON — All week long, government lawyer Carla J. Martin badgered them. She sent them 100-plus-page court transcripts. She harried them with e-mails criticizing prosecutors and fretting about the government's image. She called them at home.
By Friday, Lynne A. Osmus had had enough. As a top security official at the Federal Aviation Administration — and soon to be a key prosecution witness in the death penalty trial of admitted terrorist Zacarias Moussaoui — she did not like being used to further the lawyer's interest in making the FAA look good at the expense of telling the truth in a capital murder case.
"I didn't want to have secret discussions with her," she said.

You are correct though that I can not explain the anomaly... the rectangular shape of it is truly baffling to me, and I can not even think what could account for such a situation.
What is clear is that this 'metal fire' appeared suddenly around half an hour after impact... and shortly before molten steel began pouring down the side of the building.
No point in trying to speculate that the molten metal is aluminum... Jones' experiments have put that to rest. His experiments completely refute Dr Greenings speculations. If you support Greening, I suggest you write him and tell him to get busy and respond to Jones empirical experiments. If he doesn't, he stands refuted.

Two dimensional thinking Foxx. The rectangle can just as easily be an opening in the corner structure of the building that is allowing light from a fire beyond it to be seen. This removes the requirement for the object on fire to be rectangular and to remain rectangular during the time it is being consumed by the fire. It also increases the distance between the aluminum cladding of the building and the object that is on fire. However if this were a thermite conflagration and actually in contact with the corner columns then that aluminum cladding could not help but be consumed as well, unless you assert that the steel column would be melted at a lower temp than the cladding.
I am not speculating more than you are.I am utilizing materials and conditions known to have been present while you reject such an approach out of hand and instead search for another, exotic condition which is in no way backed up by any evidence as having been present.

These photos were taken at Ground Zero, the World Trade Center site in New York, on September 13, 2001. They were taken by someone named "Ed" who was allowed into the area by a member of the emergency response crew, at a time when all civilians -- including most journalists -- were forbidden to enter the area. As a result, these photos are just about the only close-ups ever taken of the World Trade Center site so soon after the 9/11 attacks.

There is a huge difference between the objectives of the two groups who post here. One group operates from the premise that 9/11 was and is an open ended phenomena, open to interpretation and in need of closure or at least some perspective. The other group comes to the table with a closed ended, blind faith, orthodoxy. They accept the summary of events concerning 9/11 religiously but inexplicably; from a government that lies about foreign policy, lies about domestic policy, exploits the good faith implied in democracy, operates in total secrecy, reverses all institutional checks and balances, openly practices cronyism and nepotism, is dumbing down its' citizens into a coma and then importing cheaper, subservient brain power to fill the induced void, is irretrievably mortgaging away U.S. interests and is ultimately beholden to foreign global entities'. I could go on and on and on. The point being however, is that no government in the history of the united states has demonstrated such a degree of character deficit and ill will, as this one. Why would anyone trust the integrity and intent of ANY findings about anything, begotten by this self appointed, autocratic band of thieves. Everything the bush administration engages, MUST further its' illicit interests, therefore, any investigations, past and present, MUST reflect favorably and distance the naked kingdom from the vortex of the 9/11 anomalies.
If arthur says the vase on the table is black then I know it's white. If he says the the thread is waning then I suspect it is waxing. We understand the mechanisms of disinformation more than ever. Unfortunately, we will need to employ the counter-measures more than ever.
Newton has become an asymmetric force to be reckoned with and a de-facto, poet laureate. I believe his omni-directional Ascension has red-lined the pragmatic dogmatism of arthur.
I'm here to learn the art of rhetorical, hand to hand combat. If along the way, I can chink the Armour of the official account, by attacking it from some insanely, oblique angle, so much the better. If, however, I make that my primary interest, the odds would suggest, that I'd be designing a vehicle of intensional disappointment.

In August of 2004, according to a Zogby Poll, 66% of the people of New York State wanted a real investigation into 9/11. You would think the NY State Attorney General, Eliot Spitzer, would recognize the call to action. However, he has been silent. Despite his inaction, it only stands to reason that now an even great number of New Yorkers recognize that the lies of Iraq, torture, wiretapping, Katrina, to name a few, underscore the fact that there is overwhelming evidence that we have been deceived about 9/11. In November of 2004, an independent inquiry into the events of 9/11 titled “Citizens’ Complaint & Petition” was submitted to Eliot Spitzer’s office. His deputy, William Casey personally received it. In public events Mr. Spitzer was asked for a response to this Complaint, which he acknowledged knowing about. To this day there has been no response.
Now earlier this month, in special Congressional hearings on Able Danger we see more cause for suspicion. Able Danger was a Pentagon terrorist tracking operation. News broke last summer with whistleblowers reporting they knew about Mohamed Atta in early 2000, but experienced suppression of their testimony by the 9/11 Commission. Here is another scenario where Eliot Spitzer’s behavior raises more red flags which should outrage all Americans. He barred his top aide, Deputy Attorney General Dietrich Snell, from testifying at these hearings which occurred after 248 Congressmen petitioned the Pentagon.
In the 2004 book by five-time Emmy award-winning journalist Peter Lance called "Cover Up: What the Government is Still Hiding About the War on Terror", he makes a damning statement about Dietrich Snell. "Under objective circumstances, Snell would have made an important witness before the Commission. But in the heavily-conflicted world of the Commission staff, he was hired to be one of its senior attorneys and team leaders." According to Peter Lance, Dietrich Snell "was one of the fixers, hired early on to sanitize the Commission's final report."
To further illustrate the nature of this suspicious act by the top NY law enforcement officer, according to February 15th's New York Post, "Attorney General Eliot Spitzer personally intervened with a congressional panel to get a top aide out of testifying at an explosive hearing on pre-9/11 intelligence failures... the House Armed Services Committee had requested testimony of Deputy Attorney General Dietrich Snell -- a former top investigator with the 9/11 commission -- at a hearing today on 'Able Danger.'"
How could it be that Spitzer, who has won accolades for his successful legal actions against Wall St. financial institutions engaging in fraud, has acted to suppress information that would reveal what happened on 9/11 rather than bringing the full power of his office to investigate and expose every detail leading to the truth of what happened that horrific day?
We feel strongly he's guilty of Obstruction of Justice. We feel he is complicit to treason for actual government complicity for the crimes of 9/11 for which there is overwhelming evidence. We feel he is also complicit to fraud for not cooperating with the Able Danger investigation as well as not exposing the wholesale cover-up known as the 9/11 Commission Report. By his inaction, Spitzer showed whose side he is on.
Eliot Spitzer does not represent the people of New York or anyone other than the oligarchy. The evidence is, he represents the entrenched military/industrial/ congressional machine that is reaping billions of dollars in war profits and homeland security contracts. The terror economy is winning, while Americans pay the bill with treasure and lives, while functional democracy has become a myth.
The truth won’t wait forever. It's time to send a signal, Americans want truth and accountability for the crimes of 9/11. It's time to get into the streets to show our "leadership" we won't settle for the "big lie" they want us to believe. We owe it to the victims. We owe it to ourselves. See you there!

No single hypothesis about planes and passengers has yet emerged hands-down triumphant, in my opinion. True, I am highly skeptical toward the official story that Boeing 767s struck the towers because the evidence doesn’t convince me. Maybe I’m just slow, maybe I’m on to something, and maybe we should just ignore jetliners as a big distraction that diverts attention from the fact of demolition. Yet human beings seek explanations for what happened, so speculation, hypotheses and investigations about aircraft are inevitable.
While I may not yet understand the impact holes, airplanes and such, I can’t resist inquiring about them. I’d like an explanation. More generally, if only one consequence derived from a hypothesis turns out to be false, then the hypothesis itself can be rejected. An important consequence of the Boeing 767 hypothesis is an impact hole in each tower at least as large as a Boeing 767. Impact holes smaller than a Boeing 767, assuming each plane was intact upon initial impact, would refute the hypothesis. A smaller aircraft, say, a Boeing 737 with a wingspan of only 93 feet, versus the Boeing 767’s 155 feet, would remain a viable hypothesis. Regardless, the relatively small, “neat” outline nature of the impact holes, lack of recovered black boxes, lack of major wreckage and many other facts bother me. So, my June 9 essay was basically saying, “Show me the facts that implicate Boeing 767s beyond a reasonable doubt (and put notoriously problematic eyewitness testimony and videos aside for the moment).” That’s Missouri-style reasoning, the inchworm mind and all. Certainly I’m not buying anything the bald-faced liars in government say without independent confirmation.
It really stretchs the man's credibility when he cannot even see that indeed, 767 hit the towers.

The "pancake" theory is an idealized scenario in which all the floors stay intact and pile up on each other -- this is not observed in the actual collapse in which the tower is crumbing on the way down into dust and debri with no large stack of floors.
Judy woods analysis assumes that the floors pulverize instantaneously upon impact on the way down, fall off to the sides, and innitialize the collapse of the floor below it.

That time assumes that as each floor fell it came to a complete stop before the following floor fell.
THAT simply has no relevance to the situation.
It does... "pancaking" assumes the floors all stay intact on the way down, and all of the momentum is transfered to the floors below. From the Video evidence this is not happening at all; the floors are just pulverizing into dust and debree on the spot, and going all over the place - which is where most of the kinetic energy is disapated. There was no large stack of floors pushing the building down evident in any of the videos of the collapse, instead the building crumbled all the way down. I think Judy Woods analysis was apt.
NO! the pancaking theory does NOT require that each failure occur only after the falling upper sections come to a complete stop first. The impact fails the floors and indeed would use some of the KE of the falling debris to do so but it need not come to a complete stop.
OK YID this is a pretty crucial part of the debate wouldn't you agree? You are obviously saying a 110 story structural steel building, sustaining approximately 3% damage of the whole, collapses in 11 sec.?
<<sighs heavily>>
The planes impacts and causes an immediate loss of about 3% of the total load carrying capacity of the building. The resultant fires weaken the ability of the towers to support the mass above the impact zones until the upper section finnaly drops. The falling upper section impacts lower sections with approx 30 times the energy required (Bazant-Zhou) to fail the next floor.
30 times!!

30 times!!
Edit - BZ say 30 times the force. Not the energy.
But over what fraction of the distance? And have you accounted for the safety factor yet? If not you will have to reduce that figure to 14.45 times. At most.
That of course will be compressive load, but as the columns failed due to buckling, you will have to reduce it again if you want to collapse it over one storey. That should bring it down to less than 4, but for the other tower it would be less than 3.
3 times the force over a fraction of the distance doesn't look quite so impressive does it?

All discussion of collapse omits reference to the concrete core. The only core shown in all photos of the demolition.

A tubular rectangle with steel reinforced cast concrete walls. The inner tube of the "tube in a tube construction. Steel core columns will be visible under these conditions and they are unseen. WHY?
Any argument for collapse is null and void before it begins.

Who peer reviewed Lu's paper? It's a paper submitted to a conference proceeding. If anyone here is involved in the research community, they know that conference papers usually are not reviewed, or at least not in the more rigorous way they are for publication in a regular research journal.
Also, how did Lu calculate those collapse times?

I didn't claim it was peer reviewed. Not sure why someone said it was peer reviewed.
I read the paper but didn't see anything about fall times. The paper centered more on ways of absorbing the energy to try to prevent progressive collapse.

Gordon.
Where do you get 14.45 times??
My recollection was that the overbuilt margin was 5 times design load, you are putting it at over 15 times.
Failure was due to buckling and fracture.
Any velocity of the falling upper section that continues after failure of the first columns post initial collapse simply adds to the KE of the falling debris by increasing the velocity of that debris over the velocity of the falling mass at contact with the first floor encountered. Since KE increases with the square of velocity while decreasing proportionately with any loss of mass(falling off to the side) obviously velocity has a much greater effect.

I'm not so much questioning the credibility of the paper. I'm questioning whether it was peer reviewed as someone claimed.
Since I haven't seen anything in the paper regarding fall times, it can't be used one way or another to support a position. The fact that someone said that Lu stated in an email a particular fall time doesn't help much. If it wasn't included in the paper and explained, it's not of much use.

The factor of 30 in Bazant's paper is actually optimistic, because it assumes the failure mode during all of the collapse was a maximum buckling of the columns, which takes a relatively large amount of energy compared with breaking weaker links.
There are other modes of failure which require less energy, such as breaking of column splices and floor connections. The collapse itself showed many individual un-bent columns flying about and the rubble on the ground also showed that the weaker links were broken, as most columns were individual straight pieces, as opposed to a situation with multiple columns still spliced together with the columns severely bent.
The same can be said for all of the broken floor connections seen during the collapse and in the rubble. If the floor connections had held, sections of floor still connected to columns would have been seen during the collapse and in the rubble, but they weren't for the most part. That weak link mode of failure is different than one where all of the connections are assumed to hold and maintain the integrity of the structure such that full buckling of the columns can occur.
Bazant's treatment is optimistic with respect to preventing progressive collapse. It's more appropriate for the period when the collapse had just began and columns were still in registry with one another. It doesn't fit well with the mode of failure as the collapse progressed where it became more chaotic, splices and connections failed, and the columns were no longer in registry with one another as they were when the building was still standing and was just starting to buckle catastrophically.

Christophera is a disinfo agent... comparable to Phil Jayhan and the ridiculous Pod theory.
The fact that there were 47 massive interior core columns is incontestable.
The ONE photo Christophera posts as 'evidence' to his theory is unsupportable when compared to historical evidence.
Notice that the gravity-driven collapse supporters 'attacks' against him are a sham.

Regardless of the feigned association with CTers... (IMHO)... he works with the disinfo team, as a plant to input strawman theories which can easily be refuted.

Neither of you appear to want the truth. In fact the exchanges between you appear manufactured to take up space and look like something meaningful. When in fact not only it insignificant information proportionally, it also has no possible use in showing intent.
I have a web site sharing what I know as I use it to analyze hard evidence. It's easy to see the concrete core if a person has a modicum of experience in construction. I see no one invested with evidence reasonably, logically with their opinion of what the truth of 9-11 was at the WTC.
As far as the comparison of the fact of the concrete core, the most common building material on the planet; to the pod; a suggestion induced hallucination, trick of light, error; is devious and disproportionate to a degree that exposes you.

....its apparent that Lu did an actual FEM simulation of the collapse as is detailed in the paper, and it took that long for it to finish. Although he doesnt put the time in his paper (I guess becuase he figured that it wasnt relavent) - somebody emailed and asked for it.

Peer reviewd studies supporting collapse by fire..
http://www.luxinzheng.net/publications/english_WTC.htm Out of curiosity I contacted Dr. Lu, one of the authors of this paper, in request of the simulated collapse times for the towers. He reported back that those values are:
North Tower: 1:53
South Tower: 1:32
That's minutes and seconds, obviously. I have a hard time believing that the most wildly optimistic case (fracture strain = 0.5%) yielding times like these can be in support of gravitational collapse.
