Your youtube video was nixed.  I have been looking at some of the documentaries that have been on National Geographic channel.  The best one I saw was one that explored conspiracy theories about 9/11 (the towers were brought down by controlled demolition, the Pentagon was hit by a missile), and NG did experiments to see if the official record from the 9/11 report held true.  It was fascinating to see how the conspiracy guys reacted when presented with the evidence from the scientific experiments.  It was a good two hour show.

Others I saw were reactions and remembrances from people from that day.  I will also be watching to see what comes on Sunday.
