EgyptAir black box confirms smoke on board: probe

Data from one of the black boxes of a crashed EgyptAir plane showed smoke alarms had gone off on board, while investigators found soot on the wreckage, Egyptian authorities said Wednesday.

"Recorded data is showing a consistency with ACARS messages of lavatory smoke and avionics smoke," an investigation committee said in a statement.

"Parts of the front section of the aircraft showed signs of high temperature damage and soot," it added.
