I watched the documentary that Robert de Niro introduced. It had film that (I think) has not been shown before - at least I'd never seen it. 2 Frenchmen had been filming a rookie fireman to make a documentary, so they were with that station on 9/11 and went to the towers - and they were filming inside the South Tower. They took a lot of dramatic film there, and then more as everyone ran outside after the North Tower collapsed. The most amazing thing in the whole documentary is that that engine company didn't lose a single man. It has been called the miracle company.
