Controversy and 911
I watched this film the other day on the recommendation of Scott. The basic idea is that 911 was planned by, and carried out by, the American government. The guy makes some compelling arguments but for me the most interesting thing was to see all the people who were in the building at the time talking about all the smaller explosions inside the WTC from the lower floors and how the destruction looked, sounded like and acted like a controlled demolition. It does certainly make you feel like it was planned from the inside at the highest levels.
It's worth pointing out that I have read testimony from people who were at the pentagon on the day who said that it smelt like airplane fuel… I guess it's up to you and who you believe.
The film is over an hour long but it is well worth watching it. You can download it from google videos; just click the download button on the right side of the page. see link below: link.
