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. French President Francois Hollande said he was told the flight crashed, but Egyptian Civil Aviation Minister Sharif Fathi said he preferred to classify the flight as missing.
“We do not deny there is a possibility of terrorism or deny the possibility of technical fault,” Fathi said at a Cairo news conference. “I will continue to use the term missing plane until we find any debris.”
For now, finding the airplane and any possible survivors is the priority, authorities said.
Somber relatives gathered in Cairo and Paris airports, seeking word on their loved ones. They were taken to special centers at both airports, where translators and psychiatric support awaited. In Cairo’s airport, dozens of relatives paced anxiously in a building set aside for families. Some shouted at photographers taking pictures of them, while others berated officials over the perceived lack of information.
