EgyptAir Flight 804 was a regularly scheduled international passenger flight from Paris Charles de Gaulle Airport to Cairo International Airport, operated by EgyptAir. On 19 May 2016 at 02:33 Egypt Standard Time (UTC+2), the Airbus A320 crashed into the Mediterranean Sea, killing all 66 occupants on board.
No mayday call was received by air traffic control, although signals that smoke had been detected in one of the aircraft's lavatories and in the avionics bay were automatically transmitted via ACARS shortly before the aircraft disappeared from radar. The last communications from the aircraft prior to its submersion were two transmissions from its emergency locator transmitter that were received by the International Cospas-Sarsat Programme.
