[EX Q]: (CNN) A submarine is joining the Mediterranean Sea search for the black boxes that could reveal what caused the crash of EgyptAir Flight 804. The aircraft disappeared from radar last week on a flight from Paris to Cairo. Searchers have recovered parts of the plane wreckage, including passengers' personal belongings, life vests, aircraft chairs and even body parts. But they're still scouring the Mediterranean for the plane's fuselage, and for the flight data recorder and cockpit voice recorder -- key pieces of evidence that would likely reveal what went wrong on the flight. Egyptian President Abdel Fattah el-Sisi announced the deployment of the submarine Sunday. It can reach a depth of 3,000 meters (about 9,800 feet), he said.Mourners at a Cairo mosque gather in memory of the plane's pilotEgypt uses submarine to hunt for flight data and cockpit voice recorders
