Flight MS804 was travelling from Paris to Cairo when it vanished from radar 10 miles into Egyptian airspace at 00.30am GMT without making a distress call.
Greek defence minister Panos Kammenos said the Airbus A320 made 'sudden swerves' in mid-air, lurching 90 degrees to the left then 360 degrees to the right. It then dropped from 37,000 feet to 15,000ft before the signal was lost at around 10,000 feet.
