Air France Flight 447

Air France Flight 447 (abbreviated AF447) was a scheduled commercial flight from Galeão International Airport in Rio de Janeiro, Brazil to Charles de Gaulle International Airport in Paris, France. On 1 June 2009, the Airbus A330-203 airliner serving the flight crashed into the Atlantic Ocean, resulting in the deaths of all 216 passengers and 12 aircrew. The accident was the deadliest in the history of Air France. It was also the Airbus A330's second and deadliest fatal accident, and its first while in commercial passenger service.

Initial investigation was hampered because authorities were unable to locate the wreckage; it was located nearly two years after the accident, and the aircraft's black boxes were finally recovered from the ocean floor in May 2011. The final report, released at a news conference on 5 July 2012, stated that the aircraft crashed after temporary inconsistencies between the airspeed measurements—likely due to the aircraft's pitot tubes being obstructed by ice crystals—caused the autopilot to disconnect, after which the crew reacted incorrectly and ultimately led the aircraft to an aerodynamic stall from which they did not recover.
