What happened on September 11th, 2001?

Many of the explanations I’ve heard from the government for what happened on 9/11 don’t make sense to me. I find the questions interesting and don’t have any answers myself. Here’s an hour and twenty minute documentary that asks some of the questions: Loose Change. I do not find their conclusions compelling. They simply don’t have enough information to draw the kind of wide-ranging conspiricy theories that they do. What I do find compelling, however, is the idea that many, many questions have been swept under the rug, and we may never know the truth about what happened on Spetember 11th.
