Dr. Greening's New Paper Demolishes Controlled Demolition

Of course, I can't even dream of following the mathematics, but the conclusions are pretty obvious:

1. Gravitational kinetic energy is sufficient to account for the pulverization of the concrete floors.

2. Explosives to pulverize the concrete would be prohibitively difficult to plant and would require over 2 tons of TNT per floor.

3. The towers did not fall at the free fall rate of acceleration.
