Turkish Airlines Flight 981 was a regularly scheduled flight from Istanbul Atatürk Airport to London Heathrow Airport with an intermediate stop in Paris at Orly Airport. On March 3, 1974, the McDonnell Douglas DC-10 operating the flight crashed into the Ermenonville forest outside Paris, killing all 346 people on board. At the time, it was the deadliest plane crash ever. It still remains the fourth-deadliest plane crash in aviation history, is the deadliest involving a DC-10, the second deadliest with no survivors, and the deadliest to have occurred on French soil. The crash was also known as the Ermenonville air disaster, from the forest where the aircraft crashed.
