Bull! The heat from the fires was hot enough to weaken the steel, and with the weight of the forces involved I don't doubt for a second the steel beams were bent. That said, there is no way any demolitionist would have used thermite or thermate in the demolition process. The Truthers are committed to the thermite- thermite agenda and will jump off cliffs to perpetuate a lie.
And how many other times in all of history has a fire caused a steel framed building to collapse? For example: At 8:27 p.m. on 9 February 2009, the entire building caught fire on the last day of the festivities marking the Chinese new year and was put out six hours later http://en.wikipedia.org/wiki/Beijing_Television_Cultural_Center_fire There are countless examples just like the above. Yet there are NO examples of fire causing a steel framed building to collapse. Even NIST Says the exact same thing The collapse of WTC 7 is the first known instance of a tall building brought down primarily by uncontrolled fires. The fires in WTC 7 were similar to those that have occurred in several tall buildings where the automatic sprinklers did not function or were not present. These other buildings, including Philadelphia's One Meridian Plaza, a 38-story skyscraper that burned for 18 hours in 1991, did not collapse due to differences in the design of the structural system (see the answer to Question 9). You HAVE read the official NIST reports, haven't you?
Firstly, WTC 1 & 2 sustained extensive damage from airplanes plowing through columns within the buildings. This was in addition to the fires. When the North Tower collapsed, heavy debris hit WTC 7, causing damage to the south face of the building and starting fires that continued to burn throughout the afternoon. Structural damage occurred to the southwest corner between Floors 7 and 17 and on the south face between Floor 44 and the roof; other possible structural damage includes a large vertical gash near the center of the south face between Floors 24 and 41. So to say WTC 7 collapse due to fire alone ignores the facts.

So you don't agree with the Official Conspiracy Theory™, which says that it was the fires alone. Interesting. If you'd at least take a few minutes to read the NIST FAQ (or take longer and read the full report) you would know that. Why won't people do the basics? The debris from WTC 1 caused structural damage to the southwest region of WTC 7—severing seven exterior columns—but this structural damage did not initiate the collapse. The fires initiated by the debris, rather than the structural damage that resulted from the impacts, initiated the building's collapse after the fires grew and spread to the northeast region after several hours. The debris impact caused no damage to the spray-applied fire-resistive material that was applied to the steel columns, girders, and beams except in the immediate vicinity of the severed columns. The debris impact damage did play a secondary role in the last stages of the collapse sequence, where the exterior façade buckled at the lower floors where the impact damage was located. A separate analysis showed that even without the structural damage due to debris impact, WTC 7 would have collapsed in fires similar to those that occurred on Sept. 11, 2001. None of the large pieces of debris from WTC 2 hit WTC 7 because of the large distance between the two buildings. The Official Conspiracy Theory™ says you're wrong about one of the fundamentals. Study up and try again? There's this too: The Offical NIST FAQ states that the structure fell in free fall for 2.25 seconds. Stage 1 (0 to 1.75 seconds): acceleration less than that of gravity (i.e., slower than free fall). Stage 2 (1.75 to 4.0 seconds): gravitational acceleration (free fall) Stage 3 (4.0 to 5.4 seconds): decreased acceleration, again less than that of gravity How does that happen, especially keeping in mind that the structural damage didn't cause the collapse - per the Official Conspiracy Theory™? How does a 47 story building collapse in 5.4 seconds due to heat causing a girder to "thermally expand"? Has it ever happened before? No? Isn't that interesting.

The Beijing Television Cultural Center fire was a massive blaze on 9 February 2009, in the centre of Beijing, involving the uncompleted Television Cultural Center (TVCC) building
The Beijing Cultural Centre building after the fire8. Why did WTC 7 collapse, while no other known building in history has collapsed due to fires alone?

21. Did debris from the collapse of WTC 1 cause damage to WTC 7's structure in a way that contributed to the building's collapse?
Three distinct stages characterizing the 5.4 seconds of collapse:
