Don't know if anyone is interested but over the next few days there is a lot of documentaries (eye witness accounts and such) about the 9/11 attacks

2 have caught my eye Tonight 9pm on C4: miracle on stairway B. This is the account of people who walked from the tower despite been buried in the rubble.

And Thursday 9pm BBC1 (can't remember the name) but it gives account of surviours on the floor just and below where the planes hit.
