Emotionally-packed and moving fact-based story about the passengers aboard doomed flight United 93 that was the fourth terrorist attack plane on September 11, 2001. The passengers on the flight, as a result of a delay on takeoff that placed them behind the planned attacks on the World Trade Center and the Pentagon, are able to learn of the attacks and discern that this is no mere high-jacking. While the real events that caused the ultimate crash of the plane can never be known, the events depicted would appear to be as might be expected.
