Interesting that you used the word "demolition" Ebbie.

The floors in the twin towers were 4 inches thick. Then there were the thicker floors at the bottoms of each "block." So how long did it take the pulverization you observed? Half a second? The floors in the towers were bolted, with tens of thousands of massive bolts, to hundreds of steel columns. And the floors below the impacts were undamaged and unheated. So the defenders of the government's "19 boxcutters" theory say that the buildings fell straight down, floor impacting floor impacting floor, and collapsed in 10 seconds. That's freefall speed. The successive impacts of the floors should have SLOWED the collapses. Laws of physics. Why did the buildings fall at freefall speeds?
