Wreckage from EgyptAir Airbus Crash Allegedly Spotted at Sea

Greek authorities have found "floating material" that is likely to be debris from the EgyptAir jet that crashed over the Mediterranean Sea as well as life jackets, according to the Egyptian civil aviation ministry.

The Airbus A320 passenger jet was flying at 37,000ft when it disappeared on Thursday 16km after entering Egyptian air space, EgyptAir said.

The airline has released toll-free numbers for relatives of the passengers who were on-board: 0800 7777 0000 from any landline in Egypt and +20 2259 89320 for international callers.

"The Greek military, at the moment, seems to be the authority which has the latest on the last known whereabouts of the aircraft," said Al Jazeera's John Psaropoulos, reporting from Athens.

Greek defense sources reported the discovery of two large plastic objects in the southern Mediterranean Sea 80km south of Crete, just hours after flight MS 804 travelling from Paris to Cairo went missing with 66 people on board.

EgyptAir said the plane disappeared from radar with 56 passengers and 10 crew members on board.

The floating objects were spotted in an area near an area where a transponder signal was detected earlier, the Greek sources said.

The plane made "sudden swerves" mid-air and plunged before dropping off radars in the southern Mediterranean, Greece's defense minister said.

Sherif Fathi, Egypt's aviation minister, said the possibility of a terror attack was "stronger" than a technical failure.
