A little wind drag and we get 10 seconds for a piece of rubble to fall down from the roof. The speed would also be very high and in the range of 300 km/h. That would have the momentum of a fast train, which would smash with enormous force against the floor. Such falling steel is used in 'bunker busters', which can penetrate several meters of reinforced concrete. Since the towers were extremly large, there would have been an enormous number of such falling pieses. The WTC-plaza should have looked like a traget for bombing in a jet-fighter training range. But that wasn't the case! Instead of being totally destroyed, the WTC-plaza looked almost entirely unharmed. On the followiung day the street level was clearly visible and seemingly undamaged. E.g. you can see delivery- and fire-trucks in the rubble, which looked a little dusty and had been hit by smaller parts. But the glass of their windows wasn't broken. Also the statue 'The Sphere' was a little damaged, but stood still upon its pedestal and that on the WTC-plaza. From this we can draw the conclusion, that only a few/none of the heavier parts falling down from up to 410 m made it to the ground. This fact is actually quite surprising and would deserve an explanation. Th ...
