Black box data suggest fire on board before crash

Investigators have downloaded data from one of the black box flight recorders on EgyptAir Flight MS804 and are preparing to analyze it, bringing them closer discovering what caused the jet to crash, Egypt's investigation committee said on Wednesday.

The Airbus A320 plunged into the eastern Mediterranean Sea en route from Paris to Cairo on May 19, killing all 66 people on board. The cause of the crash remains unknown.

Recovered wreckage from the jet's front section showed signs of high temperature damage and soot, Egypt's Aircraft Accident Investigation Committee said. Those were the first physical signs that fire may have broken out on the A320 airliner.
