Greece will start dispatching key information on the EgyptAir crash to Egyptian authorities on Wednesday, including data from the airliner as it flew through Greek airspace moments before disappearing, a source close to the probe said on Tuesday. Greek Defence Minister Panos Kammenos last week said the aircraft took a sudden 90 degree turn, before flipping 360 degrees in the opposite direction and plunging from a cruising altitude of 37,000 feet to 15,000 feet, then vanishing.
