What we know about the EgyptAir MS804 on Friday morning
Here is what we know so far about the EgyptAir plane crash.
* Flight MS804 set off from Paris to Cairo on Wednesday night, but vanished just under three-and-a-half hours after take-off from Charles de Gaulle Airport.
* The flight, carrying 66 people, disappeared from radar 10 miles inside Egyptian air space at 2.45am Cairo time (12.45am GMT).
* It crashed into the Mediterranean Sea about halfway between the Greek island of Crete and Egypt's coastline, or around 175 miles offshore.
* There were 56 passengers on board, including a child and two babies, and 10 crew. The airline said the passengers included 30 Egyptians, 15 French, two Iraqis and one each from Britain, Sudan, Chad, Portugal, Algeria, Canada, Belgium, Kuwait and Saudi Arabia.
* The Briton on board has been named as father-of-two Richard Osman, originally from Carmarthen, Wales. His young brother Alastair described him as a kind and loving person and said Mr Osman had just become a father to a second daughter less than a month ago.
* The Airbus A320 was built in 2003 and was flying at 37,000ft, the airline said.
* The cause of the crash is unknown but officials have indicated it may have been a terror attack. Egyptian civil aviation minister Sherif Fathi said the possibility it was a terror attack "is higher than the possibility of having a technical failure", while Alexander Bortnikov, chief of Russia's top domestic security agency, said: "In all likelihood it was a terror attack."
* Wreckage found near the Greek island of Karpathos on Thursday was initially thought to be part of the plane but EgyptAir's vice chairman Ahmed Adel later told CNN that the items were not from flight MS804.
* British military units - including the the Royal Fleet Auxiliary landing ship Lyme Bay and an RAF C130 Hercules aircraft - joined the search operation assisting the Greek, Egyptian and French authorities.
