It doesn't talk much about the damage from impact and also jet fuel.

  This is about WTC7, which was not hit by a jet, and did not come into contact with jet fuel. It's the only skyscraper ever to have collapsed from fire.

    ... after getting a front-row seat to two massive buildings collapsing. There was some serious damage to the building from the collapse of the towers, which was after all responsible for starting many of the fires. Also, as far as I'm aware, almost all skyscrapers with major fire damage are largely uncontrolled fires on one or two floors, rather than uncontrolled fires throughout the entire building.

      I know paper burns at fahrenheit 451 (thanks Ray Bradburry)... what temperature does jet fuel burn at? Or that gasoline truck? I presume it's a much higher temperature. The jet fuel that hit the twin towers was mostly expelled in massive fireballs, with some of it draining into the towers. I don't see a reason to believe WTC 7 was saturated in jet fuel. So WTC 7 was a paper & wood and fabric fire, right?
