Newsweek has reconstructed, as best they can, the events that took place on board United Airlines Flight 93 on September 11. There are still some unanswered questions, but by inteviewing the people who received phone calls from the passengers, reviewing the tape from the Cockpit Voice Recorder, and researching the backgrounds of the people known to have been on the plane, the magazine has put together a fairly complete account of what happened. Amazingly, the passengers very nearly regained control of the plane (and had among them a pilot who probably could have landed it). It’s now clear that Flight 93’s hijackers had no chance — there were some very tough, smart, competent people on board, and once they learned what the terrorists were trying to do, they were determined to stop it at any cost. And they did.
