16 fighter planes were ordered to intercept the flight shortly before the accident. Pilots reported seeing the co-pilot slumped over the controls, apparently unconscious. On Sunday, state-run NET television reported that experts in Paris decoded the box and heard the words "mayday, mayday, mayday" from a man in the cockpit. Tests on traces of blood found the wreckage have indicated that a flight attendant, Andreas Prodromou, a trained small aircraft pilot standing in as cabin crew, was the mystery person trying to land the 737 jetliner. --SP 1427 Local Time 1127 GMT
