(CNN)EgyptAir Flight 804 from Paris to Cairo disappeared from radar Thursday morning over the Mediterranean Sea with 66 people on board. Here's what we know so far:
-- Searchers have found the plane's wreckage, EgyptAir Vice Chairman Ahmed Adel said. -- "Our main concern right now is taking care of the family and friends of all those who perished," Adel said in an exclusive interview with CNN's Christiane Amanpour. -- The cause of the plane's disappearance is more likely terrorism than a technical issue, Egypt's civil aviation minister said. -- U.S. government officials have an initial theory that a bomb took down the plane. But that theory could change, with one senior administration official cautioning it is not yet supported by a "smoking gun." -- Greek air traffic control tried to reach the Airbus A320's pilots about two minutes before it disappeared -- but got no response. -- As the plane left Greek airspace for Egyptian airspace, it swerved sharply and plunged from 37,000 feet down to the Mediterranean, Greek officials said.
