EgyptAir flight MS804 disappears from radar with almost 70 on board.

An EgyptAir plane with 69 people on board has disappeared from radar while heading to Cairo from Paris, the airline says.

In a series of tweets, the airline said 59 passengers and 10 crew were on board the A320.

“The plane disappeared from radar in the early hours of this morning,” it said.

“An EgyptAir source says they lost contact with MS804 at around 02:45am Cairo time.

“It was flying at 37,000 feet.

“It disappeared about 16 kilometres into Egyptian airspace.

“EgyptAir has contacted all the relevant authorities and they are searching for the plane.”

An EgyptAir flight from Alexandria to Cairo was hijacked in March and forced to divert to Cyprus, where the “unstable” hijacker demanded to see his ex-wife.

He surrendered after a six-hour airport standoff, which ended peacefully.
