Just got on this thread & I can't believe that some guys think there's actually a conspiracy here. Two airliners, fully laden with the most highly flamable type of fuel known, crashed into the towers. A combination of extreme heat, and sheer weight of the collapsed floors brought down the towers. The towers collapsed from the very floors the planes crashed into. What some guys dream up for a story or money. Unbelievable. Go back to looking for Elvis.
