I watched a very cool program on CNN last night called Beyond 9/11: Portraits of Resilience. It was a very good Documentary made by HBO and they connected a lot of First Hand experiences from different perspectives from people who were in the towers. It got a little too political toward the end, but overall it was very good. They will allow you to watch the entire Documentary tomorrow at 8:46 AM, the time when the North Tower was hit by Flight 11.
It's worth a watch.
