I have taken a close look at the videos of the collapse on that site. VERY interesting. The spire dropped straight down. Was it because it was sturdily attached to the roof? It would have to be solidly mounted to withstand the winds and built in swaying ability of the building.

It was also interesting watching the fire come out from the floors as they collapsed. All the air, flames and all, simply squished out from between the floors.

I did time the fall. It was about 10 seconds. I posted an earlier link about an author saying this wasn't possible. Since numerous independent videos show it is not only possible, but happened, that author's credibility is destroyed.

When I studied classical physics, momentum was defined as being mass times velocity, not "momentum (mass times velocity squared)".
