If the buildings "pancaked" as the armchair experts and cover artists suggest, it would have to be slower as the resistance of each floor would slow the descent. In a measurable way. I will give you one building, I will argue about two, I will not hear of three buildings falling in perfect free fall into their own footprint EXACTLY like controlled demolition. Get with the program people. It is statistically impossible. There would have been a staggered effect as the floors impacted the floors below. But it just comes straight down with a roar.(And the sound of high explosives going off)
Just throw out all the other problems and focus on the physics of the perfect collapse of 3 buildings.
Someone here dissed this video, but if you study this very closely you will see what is going on, this is not a collapse , the building is being blown apart and at a pace with the falling debris. Gravity cannot do that.
