PantyFanatic,

I am under the impression that what happened on the plane was reconstructed from the phone calls made by passengers and crew through the telephones in the seatbacks and cell phones. I thought I read that several passengers and two crew members telephoned after the hijack occurred – one of the passengers made several calls.

Wasn’t that the flight where someone was heard saying "let's roll"?

I would think that at least a plausible reconstruction could be assembled from the records of the flight data recorder and cockpit voice recorder, these phone conversations and the forensic evidence.
