Joe Durant used to be a top investigator for the National Transportation Safety Board. (When a cop remarks to him that he was an NTSB legend, Durant says, "We're all legends. Anybody who can work a crash site automatically becomes a legend. It's a nice benefit of the job.") But the job took its toll, and Joe left the profession to work for Boeing as an engineer. This career shift... didn't save his marriage; his wife walked out and Joe was left to raise his 15-year-old daughter on his own. One year after the split, Joe's wife returns for a visit--but tragically the plane she's taking from Sun Valley to Seattle crashes, killing everyone aboard.
