Air France Flight 447 (AF447/AFR447) was a scheduled international passenger flight from Rio de Janeiro, Brazil, to Paris, France. On 1 June 2009, inconsistent airspeed indications led to the pilots inadvertently stalling the Airbus A330 serving the flight. They failed to recover the plane from the stall, and the plane crashed into the mid Atlantic Ocean at 02:14 UTC, killing all 228 passengers and crew on board.
