That sinking feeling...

In plugging around for the previous post, I came across the following article on Vanity Fair:

9/11 Live: The NORAD Tapes

Transcripts and audio from NORAD. Shows the chaos and confusion of that morning.

9:32:20
MAJOR JAMES ANDERSON: Have you asked—have you asked the question what you're gonna do if we actually find this guy? Are we gonna shoot him down if they got passengers on board? Have they talked about that?

Worth a read, and a listen.
