CAIRO: Data from one of the black boxes of a crashed EgyptAir plane showed smoke alarms had sounded on board, while soot was found on the wreckage, an Egyptian-led investigative committee said on Wednesday. The black box had been retrieved from the bottom of the Mediterranean after the Airbus A320 with 66 people on board plunged into the sea on May 19 while heading to Cairo from Paris. It had recorded the flight’s data from its departure until it “stopped at an altitude of 37,000 feet (11,250 meters),” the committee said in a statement. Investigators had previously announced that the plane’s automated Aircraft Communications Addressing and Reporting System (ACARS) sent signals indicating smoke alarms on board the plane before it went down. Egyptian investigators had confirmed that the aircraft had made a 90-degree left turn followed by a 360-degree turn to the right before hitting the sea.
