On 1 June 2009, Air France Flight 447, a scheduled flight from Rio de Janeiro, Brazil to Paris, France, stalled and crashed into the Atlantic Ocean while flying through a thunderstorm, killing all 216 passengers and 12 aircrew on board. The causes of the crash were incorrect airspeed readings due to ice blockage of the aircraft's pitot tubes, inappropriate control inputs and the pilots not taking recovery action until it was too late.
