Wow. The Internet Archive project also has archived TV footage. They have 3 days of 3 networks' coverage of 9/11 -- what an amazing historical record. Here's ABC's coverage from 0831 - 0912 on 9/11. They find out about Flight 11 at 19:50 of the movie and they watch Flight 175 flight into the South Tower at 31:30. Horrifying.

Here's a good compilation of the footage from 9/11 on Youtube. Boing Boing also has an excellent compilation of blog entries and some prophetic words from Dan Gillmor and John Perry Barlow.
