Search crews found floating human remains, luggage, and seats from EgyptAir Flight 804 on Friday, the AP reports. But they face a potentially more complex task in locating bigger pieces of wreckage and the black boxes vital to determining why the plane plunged into the Mediterranean. Looking for clues to whether terrorists brought down Flight 804 and its 66 people aboard, investigators pored over the passenger list and questioned ground crew members at Charles de Gaulle Airport in Paris, where the plane took off. In Egypt, home to 30 of the victims, grieving families and friends wondered if their loved ones would ever be recovered. Many gathered in mosques for Salat al-Ghaib, or "prayers for the absent," held for the dead whose bodies have not been found.
No militant group has claimed to have brought down the aircraft. European security officials said the passenger manifest for Flight 804 contained no names on terrorism watch lists. Experts said answers will come only with an examination of the wreckage and the plane's cockpit voice and flight data recorders, commonly known as black boxes. Egyptian searchers found the first debris from the crash around 180 miles north of the Egyptian coastal city of Alexandria. Information transmitted through the plane's Aircraft Communications Addressing and Reporting System, showed that smoke was detected in the plane's lavatory near the cockpit before it crashed.
