yes but the buildings werent just lit on fire, they were hit by an oncoming boeing 747 going at top speed with gallons of fuel. the force created by the impact and collapse of the buildings could be enough to knock down adjacent buildings. and no matter what proof you provide, i still wont beleive you for one reason. why the hell would a government like the US government want to murder thousands of its citizens and emergency personel and create endless economic turmoil? and lets face it, bush isnt really smart enough to arrange that type of thing.
