"jet fuel temperatures" were overstated by non-aeronautical, non-explosive/demolition media-appointed architectural/structural experts... along with the "weakness of trusses" theory which means that the WTC towers would then not even have withstood the actual impacts of the aircraft themselves.
There are holes in the "structural experts'" widely-promulgated-by-US-mass-media "jet fuel fire collapse" theory large enough to fly a 767 through....
The main problem is that, the jet fuel temperatures "800 deg. C" cited are not realistic in spatial distribution or heat content for the impacts that actually occurred: far too hot and too narrow in pressure distribution (oxygen-aspirated burning of petroleum fuels is both 1) volume and 2) heat energy dependent) for this event. The planes' impacts caused jet fuel to be distributed throughout a wide area (not as if they were *concentrated* , burning inside only the *confined* compressor section of a jet turbine, which is where those cited fuel temperature figures came from).
Actual collapse mechanics of the towers themselves, there's not much debate on: YES, the sequential floors "pancaked" just exactly like a controlled demolition.
Another, bigger question to ask is: How did the architectural experts come to these pat conclusions within a week or two after 9.11, when all the wreckage and rubble from the site of the largest-ever skyscraper collapse was removed and landfilled within 72 hours, without structural engineering analysis of any sort?

Questions the Media Won't Address
* Is it pure coincidence that FEMA was in New York on September 10? Why did they deny this fact?
* If WTC 1 was constructed with weak trusses and weak bolts then how did it withstand the impact of Flight 11?
* Why were staff in WTC 2 instructed to stay in the building following Flight 11's impact into WTC 1?
* How was it known that the World Trade Center was going to collapse? Why were only a select few told?
* Where were the 800°C infernos in the buildings?

* Why didn't firefighters in the impact area of WTC 2 report a blazing inferno or failing trusses before the building's collapse?
* Why did firefighters report bombs in the WTC buildings? Why did firefighters report explosions before the collapses?
* Why didn't structural debris fall from the burning towers? Why did trusses in WTC 2 spontaneously fail across entire floors?
* Why did white smoke appear at the base of WTC 1 roughly 10 seconds before its collapse?
* How did WTC 1's structure remain intact as it collapsed?
* Larry Silverstein said of WTC 7 "the smartest thing to do is pull it" (i.e. demolish it), and all evidence points to this occurring. When and why were demolition charges placed in the building?

* How could conventional fires produce temperatures in excess of 700°C in the WTC wreckage?
* How could conventional fires in the WTC wreckage burn for three months?
* Why was the investigation into the WTC collapses an underfunded farce?
