with next week's arrival of the one year anniversary of 9-11, i'm sure every single channel will have "remembering september 11th" programming scheduled. pbs has a line-up of documentaries airing september 3rd through september 11th.

in particular, "NOVA: why the towers fell," is a documentary on the trade towers and what went structurally wrong to cause them to come down so quickly. i saw it a few months ago, and thought it was very interesting.

also to note, "america rebuilds," about the clean-up effort and future plans of ground zero. and, "faith and doubt at ground zero," focusing on how the attacks challenged our spiritual views and beliefs.
