The time is 9:43 AM. The day: September 11, 2001. Conversation about the events of the day, and about the current UA93 flight unfolding. Two aircraft have already been hijacked into the twin towers, and a third has crashed into the Pentagon.
Jeff to John: UA93, type aircraft?
Doug: They pulled Jeff away to talk about 93.
John: Do we want to think about scrambling aircraft.
Doug: God, I don't know.
John: That's a decision somebody has to make probably in the next 10 minutes.
Doug: You know, everyone just left the room.
Eh? "Everyone just left the room"? Jabbering about whether to scramble aircraft? A bomb reported on UA93, UA93 has reversed course and is now heading toward DC?
Ultimately, they wouldn't notify NORAD until about five minutes after UA93 crashes in Pennsylvania.
Update: It's part of the official story as told by the 9/11 Commission that the FAA didn't notify NORAD of UA93 until after it crashed. I'm not saying it's true. It seems as if they're fabricating a story to make the FAA look as incompetent as possible. If true, the transcript of the open line is part of the fabrication.
