Unadulterated bullshit. Plenty of civil and structural engineers have explained exactly how the collapses occurred. The forces involved when the planes hit and the intense fires took place were exactly the same as when you get a controlled explosion. You will note that when a building is collapsed in a controlled explosion, the explosives are small and go off at the base. What then brings the building down is it’s own weight. In the twin towers, the weight of the floors above the impact site, as they fell, collapsed the floors beneath it In a similar sort of domino effect. Anyone involved in civil construction projects as I was, could have told you that the collapses were completely predictable.
