This thread is so full of misinformation, supposition, and faulty logic I can't stand it.

How did a STEEL building collapse from fire? (something that has NEVER happened!) Something that has never happened? EVER? You're so far out on a limb you'll say anything huh?

How did Bush see the first plane hit the WTC? He didn't. He misspoke because he's a moron with an IQ of about 85.

That metal was designed the withhold that kind of fire, yet, mysteriously failed. There is no skyscraper in the world built with metal capable of withstanding a fire fed by jet fuel. Crash two jets into the Petronas towers, the same thing is gonna happen. The same goes for the Sears Tower, Taipei 101 and all the others.

I believe there is PROOF somewhere that the FBI/CIA knew something about 9.11.01 PRIOR to the attacks, yet, don't stop it. Suspicious if you ask me. On top of it, there is a cover-up of a no investigation policy. I'll never be able to relate to those of you who think the US Government is this evil. Have they done bad things? Yes. But would they honestly allow all those people to die for some cloaked military or political purpose? No they wouldn't. Now, if in reference to the FBI, you're talking about the vague foreknowledge that something was going on, that I believe. But to think they knew exactly what was gonna happen, and they let it happen... no.

How was it possible for the World Trade Center?s two towers to have completely collapsed as a result of two jet planes? The towers in fact stood for forty-five and ninety minutes after the crashes. The official story is that the burning jet fuel caused the steel girders supporting them to melt. However, there is simply no credibly scientific evidence to support this story. The WTC towers were designed to take the impact of a Boeing 707. It is highly unlikely that fire from the jet fuel could have melted the steel girders. This is especially true of the South tower since the plane did not hit it directly. Therefore most of the fuel did not fall inside the building. The South Tower was hit second and fell first. Both towers collapsed evenly and smoothly in a manner consistent with that caused by a planned demolition... Did not hit it directly? WTF? What are you talking about???? And you don't need scientific evidence... go out and do the experiment yourself. Take some iron girders and burn them in jet fuel for 45 minutes and see what's left. Furthermore, all you have to do is closely examine the video of the towers as they burned and you can actually see the top of the tower starting to lean as the fire ten stories below starts to erode away the strength of the supporting beams. It was a slow, gradual slide to the breaking point, and once it broke, it went down. No Presidential conspiracy. No FBI Conspiracy. No CIA conspiracy.

CPYKOmega, perhaps you missed the thread where the definition of the term pull was discussed as it is used by fire fighters. I'm not going to dig it up again, so . . .

Like many occupations, fire fighters have a distinct and definite language that they use to communicate with each other. Since they are involved in a deadly occupation it is imperative that they all share the same definition for commonly used terms.

To the NYFD, the term pull is just a shorthand for pulling back and letting a fire burn.


This is a fairly common term among fire fighters. Here are some typical examples of its use:

Source
pull back.



Source
pull back.



Source
pull back. ....Pull back.


Source
pull back.



Some slightly different terminology used here:
Source
pull back.


Source
pull back.


Source
pull back.


Source
pull back.



Source
pull back..



And on, and on, and on. . . .



i notice NONE of them say "pull it". notice, also, that the infamous quote is from silverstien, who is recalling his conversation with the fire chief.

so, once again, why was silverstien directing the firefight, and why does he speak in fireman jargon?
it is easier for me to believe he has decided now is the time to blow it up, and is informing the (illuminati) firechief.

a little of the NASA-developed, copper-encased explosive, 'RDX', can go a long way. it 'slices' metal at 27, 000 ft. per second? OUCH!

but the weakening of beams from intense heat


There were no intense fires, check the witness reports, look at the holes in the towers.

911physics.co.nr...

Has a decent analysis of the WTC collapse.

Are any of you aware that the WTC North Tower fell faster than the rate of freefall in a total vaccuum ?

Here are a few comments of the junk science being portrayed on this forum: (which are mostly exaggerated comments or over-simplified analysis)

Very first and easiest correction:
It is physically impossible for something to fall(accelerate) faster than the rate of free fall in a vaccuum (9.81 m/s^2). That is unless the government invented a gravity device to up the force of gravity in that one specific area at that specific point in time, or if it was being yanked to the ground by some other force. (This point alone discredits what you are saying, and the source you obtained it from) This is basic knowledge gained in grade 11 physics.

Second, the temperate does not have to get anywhere near the melting point of steel before it begins to soften. (read any introduction to engineering materials science text) All it takes is a high enough temperature at a reasonable length of time (800*C for an hour would be near that requirement although that is just a ballpark figure, so dont quote me on it). I am just trying to say steel is not invincible and can be significantly weakend without melting.

Third - The structure of the world trade center was significantly different than most other steel buildings, so comparing this building to others that have had fires + stuctural weakening due to impacts, is like comparing apples to oranges

Fourth - The comparison of wind loads to plane impacts is not a valid comparison. Impacts have a completely different nature, of which I will not go into any detail here. Read any Engineering mechanics text if you want to indulge your curiosity.

Fifth - I do believe the the WTC is much more than the media portrays, but throwing out elaborate junk science facts is only making your opionion look flawed and wrong

an article written by Rodger Herbst; BAAE, ME

html version

or, a pdf, septembereleventh.org....

Jim Hoffman notes that Corus

Construction performed extensive tests subjecting uninsulated steel-frame carparcks to prolonged

hydrocarbon-fuled fires. The highest

recorded steel temperatures were 360 deg C.

[911research.wtc.net...] This is substantiated by Jim McMichael,

who wrote that the maximum temperature achieved in fire testing of unprotected steel supports [in the

U.K., Japan, the U.S. and Australia] was 360 degrees C (680 F), a long way from the first critical

threshold in structural steel, 550 degrees C (1022 F). Heat from the Tower beams was continuously

conducted from the heated portions to the cooler portions below, suggesting an even lower maximum

temperature. ["Muslims Suspend Laws of Physics,"www.Public-Action.com/911/mcmichael.html]

Charles Clifton is a technical expert in determining the effects of severe fire and earthquake on steel

framed buildings. He believed that fire could not possibly have caused the towers to collapse. [Painful

Questions]
