911 physics

This is an interview with the construction manager of the World Trade Center buildings. What he says only verifies what the physics of the wtc attacks clearly state: An airliner alone could not have taken down the World Trade Center towers.

In spite of the overwhelming evidence of a cover up at the Pentagon, the attack on the World Trade Center Buildings seems at first glance to be an open and shut case. We all saw the planes hit. We all saw the buildings fall.
What's the point of questioning it? The official story of the World Trade Center "pancake collapse" seems perfectly reasonable from a distance; that is until you check the math.

Let's look at the velocity at which the World Trade Center buildings fell. One of the buildings fell in approximately 10 seconds, while the other in approximately 8 seconds. (This is by official accounts) you can click here to verify for yourself
