(CNN)EgyptAir Flight 804 vanished from radar on its way from Paris to Cairo with 66 people aboard, the airline said Thursday.
The plane was flying at 37,000 feet when it lost contact overnight above the Mediterranean Sea, the airline tweeted. Although investigators are still trying to figure out what happened, French President Francois Hollande said he had been told the flight crashed.
Somber relatives gathered in Cairo and Paris airports, seeking word on their loved ones. They were ferried to special centers at both airports, where translators and psychiatric support awaited.
What we know so far:
— Passengers on board the Airbus A320 included three children — two of them infants, said Capt. Ahmed Adel, a vice chairman at EgyptAir.
— The flight left Charles de Gaulle Airport at 11:09 p.m. Wednesday local time and was supposed to land in Cairo at 3:15 a.m. Thursday. Both the departure and arrival cities are in the same time zone.
— Greek controllers tried to reach EgyptAir Flight 804 about 10 miles before it left the country’s airspace and for about 90 seconds after and received no response, the head of Greek Civil Aviation told Greek broadcaster ANT1 TV. The last time controllers were able to reach the aircraft, it was flying near the Greek island of Kea at 37,000 feet at an air speed of 519 mph with no problems reported, the official told the news agency.

Egypt’s aviation incidents
Egypt is no stranger to aviation disasters.
In March, an “unstable” man diverted an EgyptAir flight from Alexandria to Cyprus. The suspected hijacker later released all hostages and surrendered.
Last year, a Russian plane exploded midair over the Sinai Peninsula, killing all 224 people aboard. Egyptian officials initially downplayed Islamic militants’ claim that they brought down the jet, saying technical failure caused the crash.
And in 1999, an EgyptAir passenger jet made a rapid descent, plunging almost 14,000 feet in 36 seconds.
The Boeing 767, en route to Cairo from New York City, crashed into the Atlantic Ocean off the Massachusetts coast in October of that year.
Though its debris was later found, speculation remains on the cause of the crash that killed all 217 people on board.
