A black box recording recovered from crashed EgyptAir flight MS804 confirms smoke on board, according to Egyptian investigators.
The flight from Paris to Cairo plunged into the Mediterranean on May 19, killing all 66 people on board.
Automated electronic messages sent by the Airbus had shown that smoke detectors went off in a toilet and in the avionics area below the cockpit, minutes before the aircraft disappeared.
The recorded data are consistent with those messages, investigators said.
The voice and flight data recorders were recovered from a depth of about 9,800ft in the Mediterranean. The second black box, the cockpit recorder, is still being repaired in Paris.
The Egyptian investigation committee also said that part of the front section of the aircraft’s wreckage “showed sign of high temperature damage” and soot, the BBC reported.
No distress call was made from the aircraft prior to the crash. The cause remains unknown.
