Excellent Analysis of Flight 93 and Mineta
There is no audio for the first 2:30 or so, but then there is some sound. Hat Tip: Miles Kara, who notes:
Even though UA 93 was reported down with an impact time of 1003 EDT the flight plan was displayed and updated in the Traffic Situation Display (TSD) system until the flight “landed” at 1028 EDT at Reagan National. It was that “landing” that was concurrently reported to National TRACON by an FAA caller who was watching a TSD display. (In context, the FAA caller was likely either Baltimore or Dulles TRACON) It was the “approach” to that landing that became the threat to the National Capital Region, as updated to Secretary Mineta by Monte Belger, according to Mineta’s interview the next year with MSNBC.
