A design flaw in the DC-10 aircraft dooms a Turkish Airlines flight outside of Paris, with over 300 deaths. A defect in the closing mechanism for the cargo door caused it to open in flight, depressurizing the plane and causing the crash. The defect had been discovered earlier in an American Airlines DC-10, which made an emergency landing in Detroit, but no airworthiness directive was issued, and lack of clear communication led to the fatal Turkish Airlines flight.
