Loose Change

Loose Change is a documentary challenging the official version of the events of September 11, 2001 Its on Google video, I'm not sure I believe all of it but.... draw your own conclusions. It does raises some interesting points.
Among them:
How did they make cell calls from an airplane flying 2000ft plane
Why did the towers collapse when other buildings have burned for longer and higher temperatures and still stood?
How did they find DNA in the Pentagon crash but the plane was vaporized by the crash?
Watch it.
