The 1991 crash of Atlantic Southeast Airlines Flight 2311 to Brunswick, Georgia claims the lives of a NASA astronaut and a former U.S. senator and becomes an international media sensation. Commuter planes like this twin-turboprop aircraft aren't required to carry flight recorders, so investigators must rely on physical evidence to find the cause of the disaster. The strange angle of one of the propeller blades seems to offer an explanation, but in order to prove the detectives' theory, they'll need to take a huge and potentially lethal gamble.

On April 28, 1992, the NTSB published its final accident report, including its determination of the cause of the crash:
The National Transportation Safety Board determines that the probable cause of this accident was the loss of control in flight as a result of a malfunction of the left engine propeller control unit which allowed the propeller blade angles to go below the flight idle position. Contributing to the accident was the deficient design of the propeller control unit by Hamilton Standard and the approval of the design by the Federal Aviation Administration. The design did not correctly evaluate the failure mode that occurred during this flight, which resulted in an uncommanded and uncorrectable movement of the blades of the airplane’s left propeller below the flight idle position.
