I find it pretty funny that 911 truthers often cite witnesses as hearing loud bangs at the time the planes hit.
Actually, I think what you are attempting to belittle are the numerous (dozens) of firemen who are on radio and video during the events and just after describing secondary explosions throughout the towers, especially in the sub-levels, and huge series of explosions as the towers collapsed. Those lunatics must have been already forming ridiculous conspiracy theories.
Seriously, have you even watched Loose Change? Read any of the letters from engineers, architects, and scientists? Even seen what the fucking infrastructure of that building looked like?
It was designed and rated to hold half again its own weight under twice the heat at which kerosene and construction and office equipment could possibly have burned under ideal (non-pressurized) conditions. All the smoke makes it clear the conditions were extremely oxygen poor, meaning a fire not much hotter than one in your home bar-b-cue or kerosene lamp. Has your grill (made of cheap mild steel wire, by the way, not structural steel) ever collapsed on your bar-b-cue?
Where is the debris from the 'plane' that 'crashed' in PA? Where are the turbines from the 'plane' that was 'crashed' into the pentagon? Why have less than 30% of the experienced commercial pilots who have tried to crash the same type of planes into the same buildings in simulations been successful, while three supposed terrorists were able to do it after a few weeks of flight training?
What caused the other building to collapse again? I forget. It wasn't hit by a plane, and no skyscraper in the history of skyscrapers has ever collapsed from a fire, even ones that burned for days. Was it built out of substandard materials?
I suppose you all buy the 'magic bullet' theory as well?
