The twin towers fell almost at freefall on their own footprints which according to the laws of physics is impossible because of the resistence caused by air and debris. It has never been recorded in history!!!
If you compare the collapse of each WTC building, especially the collapse of building 7, to the freefall of an object from the same altitude, you would see that all three buildings came down with nearly the speed of gravity, and in case of building 7 even faster.
Only with controlled demolition can you create a vacuum in which a building comes down faster than the speed of gravity.
The towers' structural design was made of three sections that were placed on top of each other and with each tower, the plane ended up in the upper section.
According to Newtons 1st law, the Law of Inertia, says about an object in motion: Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. Now look at the following picture of the south tower as it started to collapse:
The top of the building should have fallen on the street, but instead the whole tower came down ejecting debris which could only have been caused by explosions inside the building,correcting the tops fall and keeping it on top of the second section.
