Dr. Steven Jones, physics professor at BYU, has published a paper at http://www.physics.byu.edu/research/energy/htm7.html questioning the official theory of why WTC towers fell on 9/11. He makes the case that the official explanation (weakening of steel structure due to heat) does not explain the following facts:

1. Explosions occuring on sides of building, far below where levels are collapsing and before there began to be a collaps, in video footage.
2. The presence of large quantities of molten steel in the debris, when burning jet fuel cannot melt steel.
3. Never has a building collapsed into its own footprint except thru controlled demolition. Buildings which collapse in earthquakes have fallen to the side.
4. Dip in the top of WTC 7 when it collapsed characteristic of controlled demolition.
5. Buildings fell at nearly the same rate as free-fall, which would be impossible unless supporting structure underneath had first been demolished.
6. Never before has a steel frame building collapsed solely due to fire, as WTC 7 did, and the other two apparently as well since the plane collisions themselves did not appear to cause collapse.

Controlled deomlition better fits the available observations of the fall. Viewing the video footage, the way the WTC towers fell certainly looks exactly like footage from controlled demolitions of large buildings.

Here is an interesting account of a lecture Dr. Jones gave on his investigation at Utah Valley State College: " BYU’s Dr. Steven Jones Blows the Roof off a Utah Auditorium" at http://mujca.com/jonesphysics.htm .
