I like the reliance on Radio Controlled explosive.

You know in the same towers where the Fireman's Radios wouldn't work.

Which also means that when the explosives were installed (at many HUNDREDS of locations apparently) they had to have these big batteries next to them because they would have to be in listen mode until 9/11 rolled around.

Gets funnier by the minute.

The pivot point (Core columns) simply goes straight down.

For WTC 1 this is absolutely correct. For WTC 2 the situation is more complex, but nothing went up, only sideways and down.

Prove they were all welded and what the connections looked like. I have seen hundreds (possibly thousands) of 3 storey columns that have perfect ends from the mill.


NOPE

See NIST NCSTAR 1-3C Figure 4-2

Its a recovered core column that is SEVERELY BENT (was in the impact zone) but the WELDED connection is fine.

Oh, and if weak welds are part of YOUR theory, then first YOU have to PROVE they were weak.

Almost all the "perfect ends" I've seen are from the BOLTED perimeter columns.

What about you?

The one in the background cut on an angle, was cut with oxy. There no doubt in my mind, the cut is clean, you can tell it was cut slow and steady. And the guy who cut it was most likely right handed, the cut goes down and counter clockwise, away from the body. Certainly not cut with something like thermite, at least not the way I can envision thermite cutting a column.

Hmmm, maybe so... but were there LOTS of diagonal braces? Instead of diagonal 'stubs' left from cutting off the braces, my opinion is still that it's the way to cut a column and control which way it swings on the crane rigging or which way it falls if it's not rigged.

That is a useful photo, since I had not previously understood the nature of the diagonal bracing on the mechanical floors.

However, I agree with Alan. The cuts were diagonal (mostly) for safety and control, IMHO.

In the picture on debunking911 there is a break in the metal which suggests it had been welded to something before someone cut it with a torch.

Thanks, maybe later. You've already addressed my objections when you mentioned the log/linear "extreme events" thing.

That was all I was saying, that nominal values aren't the same as the extreme values, and the existence of extreme values can explain things that nominal values wouldn't (like the evidence that some small quantities of steel actually melted).

IMHO, that's possible but I think it should be in the unlikely "column". (Get it! column!... Never mind...) We don't have evidence of where the column came from but we do have more than enough evidence of columns cut at an angle by iron workers. Even perimeter columns.

Of course rock can be crushed. So can concrete. During the cleanup of Ground Zero, it was discovered that portions of the south wall of the Bathtub had be damaged. This portion of the wall was shored up so the excavation could continue.

However, nothing at all was stated about the condition of the (thick) concrete at the bottom of the Bathtub. This implies it was in fairly good shape, there being considerable hydrostatic pressure from below. The inference is the bedrock below the concrete was essentially unharmed, at least as regards its load-bearing capabilities.

Myself, I would have though the reason for the diagonal cuts was that an horizontal cut would allow the slag to puddle on top of the lower surface and resolidify behind the cutting flame. The diagonal cut allows the slag to drip away.

There could be other reasons as well.

If they don't cut at an angle, the top part wil melt back on the lower part. Thats why they "blow" the slag downwards. Which is what you said i see now.... Excuse me for the double confirmation....

After all, none of you seems terribly interested in energy losses away from the crushing front, due to dynamic effects ala Caladine and English.

Well, we don't have any evidence of energy losses elsewhere (now that the trivial matter of seismic losses has been disposed of).

Elastic properties are unimportant. Inelastic ones are. But there is no evidence for, for example, huge S-waves deforming the lower part of the towers, even elastically. There is no evidence for any significant amount of internal pre-destruction preceding the crushing front.

But suppose there is something hidden. Its just another energy sink. So we can account for it 'at the crushing front' and we'll just fine until quite near the end of crush-down. There nothing matters as the crushing front is proceeding at about 50 m/s!

MARINES QUIET ABOUT BRUTAL NEW WEAPON

War is hell. But it’s worse when the Marines bring out their new urban combat weapon, the SMAW-NE. Which may be why they’re not talking about it, much.
This is a version of the standard USMC Shoulder Mounted Assault Weapon but with a new warhead. Described as NE - "Novel Explosive"- it is a thermobaric mixture which ignites the air, producing a shockwave of unparalleled destructive power, especially against buildings.

A post-action report from Iraq describes the effect of the new weapon: "One unit disintegrated a large one-storey masonry type building with one round from 100 meters. They were extremely impressed." Elsewhere it is described by one Marine as "an awesome piece of ordnance."

I thought about this, and I'm gonna tell from working with stuff hooked up to cranes, you never want to have things swinging if you can help it. If you had something like a column hooked up to the crane and you were cutting it you would want it to stay right were it is once it's severed.

Tell that to every other CDiot.

Thermobarics will knock stuff over and kill people, but they won't cut steel.

Neither will they pulverize concrete. They're low-explosives, like ANFO, except ANFO you can load into predrilled holes. You can't do that with a fuel-air mixture.

And the link recently posted of Mohammed's drawing showed a radio-controlled bomb set at the base of a perimeter column. That wasn't a thermobaric bomb, was it? If so, it wouldn't have had any effect on the column.

Was it thermite? If so, it would've simply drained straight down, producing no blast at all, because thermite doesn't go BANG!.

So thermite won't explain the "BANGs" heard, and thermobarics won't cut steel, and you're saying that "nobody is claiming that conventional explosives were used".

I think that *All* the other CDiots are claiming that some explosives are being used, but none of them are willing to state which, because there are logical arguments against any of them.

You'd rather just insinuate that some explosive placed someplace caused something... When you get definite about things, it gets easy to debunk the CD theory, so you stay vague deliberately.

As for the *Profit Motive* behind the CDiots, I wish it were that easy. These CDiots aren't after the Truth, and the money they collect isn't all they're after, either, they're trolling for "True Believers", people willing to accept all their NWO bullsh*t, and get mad enough to go kill cops and feds and bomb buildings, themselves. Note how MalmoStooge was so fond of that guy who refuses to pay his income taxes. This is an appeal to the ignorant Americans who resent their taxes going to support social programs. This is one of the key beefs that White Supremists harp on all the time. Him tossing that into a discussion of 9/11 was just casting a broad net, hoping to find a White Supremist he could recruit to become a terrorist.

It's an orchestrated effort, and the motives aren't monetary, they're political. They want to recruit terrorists, and they figure the longer they play this game, the more idiots they can recruit.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to FIGS. 1 and 2, the apparatus 1 for cutting target material of the present invention is provided with a housing 2 having an inner cavity 4. An elongated nozzle 6 extends from the inner cavity 4 to an exterior surface 8 of the housing 2. In operation, exterior surface 8 of the housing 2 may be positioned generally adjacent to a surface 10 of target material 11 to provide the elongated nozzle 6 a line of engagement between the cutting apparatus 1 and the surface 10, or {character pullout}cutting zone{character pullout}, of the target material 11. The elongated nozzle 6, which extends from the inner cavity 4 of the housing 2 to the exterior surface 8 of the housing 2 may have a length L of about 0.3 to 1.5 inches. In the form shown, the target material 11 may have a thickness t. The preferable range of thickness t for materials cut by the apparatus 1 of the present invention is about 0.25 to 2 inches. The region where the cutting apparatus 1 performs its cutting function on these materials is preferably of a substantially uniform thickness.


3. The apparatus of claim 2, wherein said thermite charge includes a powder comprising, by weight, about 15% to 20% aluminum, about 78% to 85% CuO, about 1% to 3% SiC, and about 0.2% to 4.0% nitrocellulose.

Maybe then Dr. Bazant would have come to suspect that the strongest core columns were subject to concussive charges placed close to the welded junction of the three storey high core column sections. This gives cause and effect for the previous observations that the expulsions of dust and debris issued every three storeys down the building and not every storey. It would also explain why the expulsions issued firstly from the mid wall areas because they were directly opposite the core columns which were being attacked.

To confirm his suspicions and his role as the fall guy he may have tried to examine the steel recovered from the debris pile. With his engineering knowledge he, like other members of stj911.com, could envisage and identify the type of failure which would be expected in a welded box column which had been subject to an explosive charge in this manner.

In one end of the column he might expect to find two opposite concave faces, one concavity caused by the concussion of the explosion the other caused by the flanges tearing across each other. Such as in the column in this picture

Referring now to FIGS. 1 and 2, the apparatus 1 for cutting target material of the present invention is provided with a housing 2 having an inner cavity 4. An elongated nozzle 6 extends from the inner cavity 4 to an exterior surface 8 of the housing 2. In operation, exterior surface 8 of the housing 2 may be positioned generally adjacent to a surface 10 of target material 11 to provide the elongated nozzle 6 a line of engagement between the cutting apparatus 1 and the surface 10, or {character pullout}cutting zone{character pullout}, of the target material 11. The elongated nozzle 6, which extends from the inner cavity 4 of the housing 2 to the exterior surface 8 of the housing 2 may have a length L of about 0.3 to 1.5 inches. In the form shown, the target material 11 may have a thickness t. The preferable range of thickness t for materials cut by the apparatus 1 of the present invention is about 0.25 to 2 inches. The region where the cutting apparatus 1 performs its cutting function on these materials is preferably of a substantially uniform thickness.


3. The apparatus of claim 2, wherein said thermite charge includes a powder comprising, by weight, about 15% to 20% aluminum, about 78% to 85% CuO, about 1% to 3% SiC, and about 0.2% to 4.0% nitrocellulose.

The person I was originally responding to said thermite had to go straight down.

This device appears to direct the thermite (I have never seen it used).

Gordon shows what is possible. I don't think anyone is claiming they have everything figured out (he is making good progress).

If the evidence had not been destroyed (without testing explosives ) we would not be dealing in hypotheticals (using videos for evidence).

By design, as I said. They don't care whether they can get someone to strap explosives to their chest because they believe in thermobaric bombs (which use conventional explosives, BTW, so the bomb-sniffing dogs would "alert" on those) or C4 or thermite or thermate or, for that matter, Invisible Godzilla, just so whatever BS theory they'll buy will convince them to kill themselves and others, that's all they're looking for.

If they can sell T-shirts in the process, all the better, then they'll have the money they need to buy the explosives for the vests.

And thermite STILL doesn't go BANG!.

Anyone can see the concrete was pulverized.


The OKC bomb collapsed the floors, which then broke apart as they collapsed, as the WTC floors did, by the process I've already described more than once. The blast itself didn't pulverize the concrete, nor could a thermobaric bomb by its blast. A thermobaric bomb overloads the structure causing it to fail. To pulverize concrete directly you need high-explosives, which, regardless of whatever a non-technical person says, thermobaric bombs *aren't*.

It wasn't the thermite that made the loud noise, it was the iron pipe that contained the heat and pressure until it failed.

Can you explain to me why non-idiots planning a covert CD would make thermite go "BANG!" when it isn't necessary? Were they *deliberately* creating evidence of a CD? Thermite, on its own, makes a hissing sound as it burns (and burning is all thermite does, it's the aluminum stealing the oxygen from the rust that powers the thermal reaction).

So if you can burn through a horizontal patch of steel, quietly, or you can add an unnecessary airtight container to it and make it go "BANG!", and you're trying to be stealthy to keep your actions a secret, why do you make it in a way that makes a loud "BANG!"?

Thermobaric bombs use high-explosives to drive the fuel into an aerosol and later to detonate it (with an additive to send ignition sparks throughout the aerosol cloud). Why not a low explosive? Because a low explosive burns slow enough that the fireball would ignite the fuel before it became an aerosol.

High-explosives are used to put out oil well fires, employing the same phenomenon.

The FBI doesn't own all the bomb-sniffing dogs in NYC. So I suppose the rest of them were recruited by the NWO to keep their mouths shut...

You're the one who's claiming that the ANFO pulverized the concrete. I've already described the means by which a low-explosive bomb like ANFO can drop a building, and I've already explained how falling chunks of concrete break into smaller chunks plus concrete dust. It's up to you to show how a low-explosive can exert enough stress in concrete to pulverize it if you're asserting that the WTC was collapsed without high explosives and that the concrete dust resulted from explosives, not from the "ball mill" process I've described more than once.

So, please tell me how a low-explosive can pulverize concrete? Enlighten me.

It depends on position in the confined space if it is HIGH or LOW pressure:

Figure C depicts the same explosive charge detonated in the center of a room. The shockwaves are reflected by the walls, producing zones of amplified pressure, in particular at the corners. Figure D depicts the pressure–time graph for this case. Unlike the uniform decline of pressure over time shown in Figure B, the pressure oscillates over time. The effect is non-linear; shock reflection in corners can multiply the peak pressure several times.

For someone who thinks he understands thermobaric explosions you sure are IGNORANT ( I have even provided links).

The military has computer software that can simulate and calculate the pressure in a confined area.

I don't think thermite could do the job alone (might leave some of the tower standing and slow down the clean-up).

I have never listened to a CD without the windows removed (have no idea how load it would be).

Low pressure explosive used to push the columns at the splices (not as distinct a sound as high explosives) along with thermate (to weaken the connections) might be enough.

I am sure someone would be able to figure out an explosive the dogs could not recognize after detonation .The chemical residue would be more of a problem and that is why the steel was quickly recycled.

Two videos of thermobarics "shoving" the walls:


Precisely what they show.

None of the buildings were concrete, and even the mud-brick how basically just fell down. The rubble was just bricks that weren't stacked on top of each other anymore. The house got shoved apart, much like your own article said. No pulverized concrete. Let me know if you find something that shows concrete being pulverized by a thermobaric bomb.

I've seen videos of them shot in super-slow motion photography, and yes, they're effective against personnel, and yes, they'll push on a structure and make it fail. No, it isn't the same as a high explosive. The shockwave onset isn't fast enough to concentrate the forces generated faster than the concrete can distribute the forces throughout its mass. The analogy between a punch versus a shove is a good one. Push someone hard enough, he may fall over and hit his head on the ground. It isn't the same as dropping him with a knock-out punch. The punch delivers more power to a local area, which is how bones get broken. The energy in the punch is delivered too fast for it to be transmitted throughout the body, so the effect is local and devastating, unlike a shove.

Maybe you should look for a video that shows what C4 does and compare the two. It isn't a nitpick, there really is a difference.

[/QUOTE]don't think thermite could do the job alone (might leave some of the tower standing and slow down the clean-up).[QUOTE]

Let me get this straight - You think that they could've destroyed *most* of the WTC with thermite, which makes no appreciable sound, so there'd be very little chance of getting caught, but they figured they'd go ahead and use MILITARY THERMOBARIC BOMBS just to make the cleanup quicker?!?

They'd be so stupid that they'd make bombs that people could hear and see, which would leave evidence that could PROVE they did it, just to make the cleanup QUICKER?

!!!!

Let me do your work for you.

Steel was the only thing holding the building up. Thermite can cut steel. Thermite could've conceivably cut the main columns, in one place, which would've caused the building(s) to collapse.

So why all the "explosions"?

The answer is, there were no explosions. As I've explained a bunch of times, when a column or truss fails under load, that suddenly-unbalanced force recoils into the structure, which is steel, and the recoil travels the length of the structure at the speed of sound in steel. Which is 20x the speed of sound in air. Which is why a failed strut or truss 80 floors up, "BANG!", gets heard at ground level before it gets heard through the air. It traveled through the steel and coupled to the foundation and that's how you get loud noises coming from the basement. Air is a lossy medium, so the direct air-path gets attenuated more than the steel path, as steel isn't as lossy as air. (Especially when there's smoke/dust in the air.)

OK, so the BANGs aren't caused by explosions, that's just what steel structures do.

So the people who say they heard "explosions" didn't hear explosions, they heard the steel structure transmitting the impulse-failed loads.

So why bother with thermobaric anything, if all you need to do is cut the core columns? Thermobarics are loud as he!!, and you don't need them to drop the building. Also, look closely at those videos, they create a visible shockwave. With all the video cameras aimed at the WTC, don't you think any of them would've seen the shockwaves that are clearly visible in all the videos you provided links to? Wouldn't that be the "smoking gun" of a CD?

So, no thermobarics. Not needed, you can drop a building with nice, quiet thermite. No BANGs.

Of course, if you just get the core hot enough that it loses, say, 50% of its strength, simultaneous to the loss of lots of the structural integrity of the curtain wall on one side, the building will drop on its own. Fire will weaken steel that much. Especially a fire started with all that jet fuel.

So you don't need thermobaric bombs OR thermite, just an airplane going 450mph with full tanks.

Oops! No CD necessary to drop the WTC towers.

QUOTE

Since this topic has come up a couple of times, let me address it.

The reason they didn't declare the whole WTC site as a *crime scene* was that there are protocols and policies that apply to how evidence is collected, tagged, and stored. Those protocols would've required the cleanup to take place by forensics teams, not firemen. Each of the concrete chunks would've required bagging and storage in the Police Evidence Lockup, like it was a crack rock or a gun used in a robbery.

Even if you feel that they could've "bent the rules" and still treated everything *sensible* as evidence, allowing the forensics teams extraordinary discretion to "cherry-pick" through the evidence and decide on-the-fly which stuff looked interesting and which stuff didn't, there are only a handful of forensics people in NYC, and thousands of firemen. And there were human remains in the rubble, starting to rot. Guiliani had good reason to do what he did, which was to expedite the cleanup.

Maybe you recall that when it happened, everyone said it'd take at least two years to clean up the mess. He got it done a lot quicker, and that was good for NYC, in general, because the site, as it was, was wrecking the local economy. (Would you want to eat pizza downwind of rotting human remains?)

The amount of steel was enormous, more than could reasonably be stored anywhere. Treating it like the NTSB would've, as some have suggested, would've required reconstruction of the WTC at least to the level where all the pieces would be reassembled to show the point of impact and the first-collapsed floors. Except those steel members weren't numbered so you couldn't exactly know which ones to keep and which ones you could scrap. You can't tell one from the other, so how do you go about reconstructing anything?

And you're supposed to store that steel someplace like it's evidence? That means secure from theft or tampering. Which would mean armed guards watching it around the clock, and not just one, because you'd have to either build someplace big enough to store all the steel from all three WTC towers, or hire guards to surround the heap 24/7.

And why?

You'd still assume they'd tampered with the evidence if it didn't support your CD theory.

So why bother?

They did keep some of the steel from the towers for analysis, as indicated in the NIST reports, sufficient to do engineering analyses. It was a representative sample, and it was big enough for supporting the science of the study.

The cause of the WTC attacks was someone else's responsibility, not NIST's. NIST never said "Osama bin Laden plotted the attacks".

Osama bin Laden said that himself. (Why don't you take his word for it?)

Myself, I would have though the reason for the diagonal cuts was that an horizontal cut would allow the slag to puddle on top of the lower surface and resolidify behind the cutting flame. The diagonal cut allows the slag to drip away.


Well yeah, kinda sorta, or to an extent. But when cutting, the idea is to blow a path through the heated up steel. If you're not blowing all the way through making a clean cut, then you need to increase the oxygen pressure on the gauge/valve. You'll can have a slag trail hanging down on the inside edge, but it shouldn't be 'in the cut'. If so, then that would show an inexperienced cutter.
To be honest, most of the cuts I've seen weren't very good ones, but (here I'm going to use an expression heard quite often on rush jobs) they "weren't making Swiss watches", just trying to get it cut. So yeah, it wasn't like building the structure where you sometimes need to trim a piece to make a good fit... then you'd be set up to make a good clean cut.

I thought about this, and I'm gonna tell from working with stuff hooked up to cranes, you never want to have things swinging if you can help it. If you had something like a column hooked up to the crane and you were cutting it you would want it to stay right were it is once it's severed.

That's correct, but... You rig it to the crane and boom him down or up, to the left or right, or whatever's needed to get it plumb, but you can only get close, so there's subject to be a little swing virtually every time. Watch ironworkers picking a load, they have tag lines and "hands on" when the load first gets clear, because it's almost never at the exact centerline pick point.

The reason they didn't declare the whole WTC site as a *crime scene* was that there are protocols and policies that apply to how evidence is collected, tagged, and stored.  Those protocols would've required the cleanup to take place by forensics teams, not firemen.  Each of the concrete chunks would've required bagging and storage in the Police Evidence Lockup, like it was a crack rock or a gun used in a robbery. 

Even if you feel that they could've "bent the rules" and still treated everything *sensible* as evidence, allowing the forensics teams extraordinary discretion to "cherry-pick" through the evidence and decide on-the-fly which stuff looked interesting and which stuff didn't, there are only a handful of forensics people in NYC, and thousands of firemen.  And there were human remains in the rubble, starting to rot.  Guiliani had good reason to do what he did, which was to expedite the cleanup. 

Maybe you recall that when it happened, everyone said it'd take at least two years to clean up the mess.  He got it done a lot quicker, and that was good for NYC, in general, because the site, as it was, was wrecking the local economy.  (Would you want to eat pizza downwind of rotting human remains?)

The amount of steel was enormous, more than could reasonably be stored anywhere.  Treating it like the NTSB would've, as some have suggested, would've required reconstruction of the WTC at least to the level where all the pieces would be reassembled to show the point of impact and the first-collapsed floors.  Except those steel members weren't numbered so you couldn't exactly know which ones to keep and which ones you could scrap.  You can't tell one from the other, so how do you go about reconstructing anything?

And you're supposed to store that steel someplace like it's evidence?  That means secure from theft or tampering.  Which would mean armed guards watching it around the clock, and not just one, because you'd have to either build someplace big enough to store all the steel from all three WTC towers, or hire guards to surround the heap 24/7. 

And why? 

You'd still assume they'd tampered with the evidence if it didn't support your CD theory. 

So why bother?

They did keep some of the steel from the towers for analysis, as indicated in the NIST reports, sufficient to do engineering analyses.  It was a representative sample, and it was big enough for supporting the science of the study.

The cause of the WTC attacks was someone else's responsibility, not NIST's.  NIST never said "Osama bin Laden plotted the attacks". 

Osama bin Laden said that himself.  (Why don't you take his word for it?)


This is a photo of the clean-up of WTC7. The picture was taken on Sept 27, 2001. All the steel is already removed from WTC 7. This is unbelievable, even if you planed ahead of time, it still is amazing. In the real world, they would be deciding the best way to investigate the only steel building to totally collapse from fire.

There was absolutely no reason to remove the steel from WTC7 (would not hold up the search and rescue of the other buildings). NIST still does not understand the collapse.

look. i really don't know what you're trying to make me imagine i see.

i do know, that the crush up/crush down theory requires the top to act as a rigid body, ie. keeping it's structural integrity, and the bottom part is supposed to be getting crushed and deformed and is supposed to be unable to support the sudden impact from the falling 'mother of all sledgehammers'.
well it WAS stopped, because anything below the red line didn't budge, deform, buckle, peel, pop, or give up the ghost in any way whatsoever. so, if you think bringing the plane's impact point into the argument is at all valid, i suggest you redo your homework.


what is see in the first moments of collapse, is a bright white flash from through the smoke in the middle of the wall at initiation(right side of the screen), and right about where the bottom red line was drawn by gordon ross, and i see that the top part has broken apart itself as it descends, and i see that the bottom part, ie. at the level the bottom red line was drawn by gordon ross, doesn't budge.
the whacky OCT math does not reflect this physical reality. it claims the bottom was breaking apart while the top portion kept it's shape, and this top chunk was some kind of unstoppable hammer. it was dust and kindling sticks, as is clearly shown in the fine video you linked to.

here, i can do links ... watch the top fall apart, while the bottom remains RIGID in this video. look for the flashes, too. there is more than one, but there is a very obvious one at collapse initiation.


and, regarding thermobarics, DAMN that's an impressive fireball.

and regarding whether thermobarics or thermate or rdx were used, (or spacebeams and nukes and a tesla howitzer), and whether the triggers were wired or wireless, ....

they used them all(possibly). each device has a different function. weaken slowly with thermate, than a thermobaric blast or two, and then some rdx.

also, at the same time the spray on rocket fuel 'fireproofing replacement' was triggered. (thanks for that neu fonze)

why do OCTs insist on one type of device? and they accuse 'us' of 'one dimensional thinking'.

You left out the *airplane impact* part of that. The impacts damaged the structures, so it wasn't just the fire that did the deed. Damaged structure from airplane impact plus weakened remaining structure due to the heat from the intense fire = collapsed WTC tower.

And steel buildings collapse from fire all the time. It isn't even considered newsworthy. It's a routine occurrance.

I looked at the video four times after reading your post, and I still can't see anything that looks suspicious. It's a burning building, still on-fire, and when it starts to collapse, the flames that were inside got shoved out with the air in the collapsing floor.

Those "flashes" are just flames getting blown through the standing smoke.

Also, they start *after* the building starts to fall. Was the building structure psychic and started falling before the "explosives" went off, or was the speed of light really slow that day?

You guys need to see some real explosions before you go off saying anything in that video looks like an explosion.

You do understand that when the ceiling drops to the floor, that the air that used to be between the floor and ceiling has to get out of the way, right?

Do some simple math, calculate how fast that 20tons of air per floor has to move to get out of the way of the falling ceiling. Here's a hint: It starts out going slow, but has to speed up as the ceiling gets closer to the floor. When the air escapes, it takes smoke, dust, and flames with it.

Look again at those thermobaric bomb videos. You can see the shockwaves. If a thermobaric bomb went off, don't you think you'd see the shockwave going through that cloud of smoke and dust? The field of view of the camera on the WTC included the full width of the WTC tower, and video is 30frames per second, so you'd see the shockwave propagating out through the smoke/dust. What you're calling a "blast" is actually just the air getting out of the way of the falling building.

Exactly what you'd expect, if you understood simple physics.

There's no mystery here, only the physics that you don't get.

Hello Newton,

That's an interesting video. I disagree that is does not show the upper block to behave rigidly, however it seems that the failure zone might be located higher than I thought. It is hard to count the floors but it seems that the floor that ejects lots of flames (that's hot combustion gas from the fire floors IMO) might be located around the 98th floor and the bulk of the gas seems to be ejected from it quite some time into the collapse. I don't see how to reconcile this with the collapse beginning around the 96th storey. This would seem not to be accounted for by the hypothesis that the crush down zone is merely hidden behind the perimeter wall. The tilt also occurs in the wrong direction to account for the late ejection of the gas on this visible side of the building.

I wonder how David B. Bensons (pure crush-down) model would match NEU-FONZE's data if the collapse were taken to be initiated something like four floors up (at the 100th storey, say).

[On edit: this might produce skewed results if the greatly increased weights of the hat-truss floors have not been accounted for in the model.]

I think a bit of initial crush-up taking place concurrently with the crush-down would not necessarily make a very significant difference. Allowing for some crush up would also reduce the initial load at the level of the crush down front, so that the net acceleration of the top could be similar to what pure crush-down predicts.

First, I need to find someone who died and tie their death to Invisible Godzilla.

I was thinking of finding someone who'd died mysteriously, who was somehow linked to Area 51 (the invisible part) or having something to do with reptiles or biochemistry (the Godzilla part), but then I realized that since this is a conspiracy theory, death from natural causes just makes it all the more convincing that he was murdered, and then I realized that he could have no associations with anything Invisible Godzilla-like, and that would make it even better, showing how diligently the MiB were to cover-up any and all documentary evidence of his connections to Invisible Godzilla.

Now that I think of it, I don't even need a real person, I can just make up a name and claim that he was "disappeared" and his identity erased as part of the coverup.

Now, all I need is a cover-shot photograph that proves Invisible Godzilla can't be seen, and I'm ready to go to print.

See NIST NCSTAR 1-3C Figure 4-2

Its a recovered core column that is SEVERELY BENT (was in the impact zone) but the WELDED connection is fine.

Oh, and if weak welds are part of YOUR theory, then first YOU have to PROVE they were weak.

Almost all the "perfect ends" I've seen are from the BOLTED perimeter columns.

Arthur
Dr. Abolhassan Astaneh-Asl in his examination of the WTC columns, came to the conclusion that the core splices were not full strength welds.
QUOTE
The splices of the columns were in most cases, field partial penetration welds or cover plate splices. However, since the core columns were gravity columns with relatively high compression in them and remote likelihood of being subjected to tension, the column splices in the core appeared to be minimal erection splices.
That particular column, C-88a, was suspected of being severed by the plane impact. It could be that at the time of the plane impact, that it was sufficiently loaded and braced to protect the welded splice, or it's possible that some splices were welded deeply and quite strong. Notice how the upper end of the column separated at the plate connections and bent towards the plane impact direction. I assume the southward bend was due to the impact of the upper block. The plate separation may have resulted from the plane impact.

The Wichita (Kan.) Fire Department sent a second alarm as they turned out for a 1971 fire in an automobile shop with a steel-trussed roof because of the dramatic loom-up of smoke. Four firefighters (including the chief) died in the subsequent roof collapse, which was accelerated by heavy auto parts stored on the truss’ bottom chord.

The worst firefighter truss disaster was the collapse of a steel parallel-chord truss, which killed 13 Brocton, Mass., firefighters in the 1940s. More recently, Wakefield (Mass.) firefighters properly preplanned a lodge hall and were out of the building when a similar truss failed.

Until you show conclusively that explosives were used, you cannot say explosives were "involved...no question". The burden is on you to provide valid evidence or conclusive evidence that the people involved(firefighters, police, etc.) were not only corrupt in hiding evidence but guilty of murder either before or after the fact.

WTC 7 obviously fell because of damage and fires caused by the fall of tower 1, which fell because of all the damage and widespread fires caused by the impact of an aircraft.

The fires spread rapidly and moved from fuel to fuel. The heat was applied to those trusses for about 45 min. in the case of 2, 1 hour for 1 because they were at the top of every floor(where the heat rises and accumulates). Once warpage and heat induced weakening reached beyond a certain point the towers fell, just as all all steel structures will. Without substantial fire proofing(IE steel reinforced concrete, etc) solid steel CANNOT stand up to fire.

WTC7 STEEL IS ALL REMOVED 16 DAYS AFTER THE ATTACK!



The largest CD in history (47 storeys) is cleaned up in less then 16 days and recycled. It normally takes 3-6 months to clean up smaller CD sites.

The public did not have access to the site and it was cleansed by private contractors. The proof should be on those that conducted the (non)investigation of the crime scene to prove explosive were not used in a collapse that looked just like a CD.
