Turkish Airlines Flight 981

Turkish Airlines Flight 981 was a scheduled flight from Istanbul Yeşilköy Airport to London Heathrow Airport, with an intermediate stop at Orly Airport in Paris. On 3 March 1974, the McDonnell Douglas DC-10 operating the flight crashed into the Ermenonville Forest, 37.76 kilometres outside Paris, killing all 335 passengers and 11 crew on board. The crash was also known as the Ermenonville air disaster.

Flight 981 was the deadliest plane crash in aviation history until 27 March 1977, when 583 people died in the Tenerife airport disaster. It remains the deadliest single-aircraft accident without survivors, the second hull loss, the deadliest accident involving the McDonnell Douglas DC-10, and the deadliest aviation accident to occur in France.
