I saw the same video that Greg and everyone else did. Those buildings FELL. No controlled demolition. The planes weakend it. The fuel burned and weakened the steel beams that remained. Hundeds of tons worth of the remaining floors SQUISHED the damaged floor, adding tons more which then SQUISHED The floor below that and so on. The combined weight plus the gaining momentum of all of that weight is what brought down the twin towers. No Dynamite required.
