Reply #147: Okay, I believe you.

It takes longer than 9.2 seconds for 11 colored billiard balls to fall to the ground from 1362 ft. when the higher ones cause the lower ones to start falling when they match their height and with no force acting upon them except gravity.

But that does not prove anything at all about how either one of the Twin Towers fell. It is a gross oversimplification.

So, for the building to be collapsed in about 10 seconds, the lower floors would have to start moving before the upper floors could reach them, by gravity alone. Did we see this? I believe it's pretty clear in some of the videos. The "wave" of collapse, progressing down the building, is moving faster than free-fall speed. This would require something like a detonation sequence.

But the buildings did not fall in 10 seconds, therefore you have not proven what you are trying to demonstrate.

I think it is very clear that the wave of collapse is slower than free-fall in the videos. There is clearly debris from the buildings falling faster than the building is collapsing. Plus, they each took longer than 10 seconds to fall - which means they had to be collapsing slower than free fall speeds. (About %60 slower than the rate of free fall for a 15 second collapse time.)
