That's pancake not free fall. As I keep on tell you free fall is when NOTHING IS THERE TO STOP IT.

We don't have equipment to tell us the exact speed of building.
It was very close to free fall speed. It does not have to happen like you say. Why not read the reports which you are still refusing to. Even after a year or what ever it was from the last time we did this.
The structure is all linked to each other. Which is why you have a slow fall speed to begin with. It buckles collums ahead of the collapse wave as you would expect. Which means for part of teh fall there is basically no resistence. Until it starts piling up at the bottom due to debris. If part of the building moves at the top. It is going to buckle and snap securing points much further down. It is not pancaking.
