A black box recording from crashed EgyptAir flight MS804 has confirmed smoke on board, Egyptian investigators said on Thursday. Automated electronic messages sent by the plane had shown that smoke detectors went off in a toilet and in the avionics area below the cockpit, minutes before the plane disappeared. The recorded data are consistent with those messages, investigators said. 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.
