Flight 801 is headed for New York, from a small South American republic. It's a long, long flight, already two hours under way, when the captain calls Angie Parsons, the head stewardess, to the cockpit. They are in trouble. What kind of trouble? Mechanical, or man-made? Certainly there were no signs of it as Angie made her way down the corridor of the half-filled plane with the flight manifest as requested by the pilot.
