The official story, that WTC7 collapsed as a result of damage from falling debris, has one huge logical flaw in it. Or, not a flaw maybe, but an admission of the controlled demolition of the Twin Towers. For how could a 'pancake collapse' of a building falling under its own weight be responsible for ejecting debris hundreds of feet outwardswith a force capable of making a huge '20 storey hole' in the South side of another structure - without the use of explosive charges?
