Search crews on Saturday returned to the area where debris from the EgyptAir plane that crashed into the Mediterranean Sea was found.
The Airbus A320 crashed shortly after entering Egyptian airspace early Thursday. It was flying at 38,000 feet when it suddenly swerved left 90 degrees, then right a full 360 degrees before descending thousands of feet and vanishing from radar.
Here's the latest information about the disaster that killed all 66 on board:
What pieces of the wreckage have been recovered?
Egyptian military forces found debris, including body parts, from the missing plane 180 miles from the Egyptian coastal city of Alexandria. Photographs released by the Egyptian Army show little remains of the devastation — just mangled bits of debris, tattered clothing and a life vest, among other objects.
Authorities found evidence of smoke in multiples places on the plane just moments before it went down. The information comes from an automated system on the aircraft that sent digital messages before it vanished from radar.
Not found yet: the plane's black boxes, which contain voice recordings from the cockpit and flight data. Investigators are eager to locate the devices because they can help determine what caused the Airbus A320 to plummet into the ocean.
What's the likelihood of finding the black boxes?
The boxes emit "pings" that can be detected with sonar, with batteries that can transmit the sounds for 30 days. After that, it's extremely unlikely authorities would be able to find the devices. The waters in the search area are 8,000 to 10,000 feet deep, and the pings can be detected up to a depth of 20,000 feet.
A French Navy boat equipped with sonar that can detect the pings began traveling to the search zone Friday. It will take two to three days before it reaches the area.
Was it a terror attack?
We don't yet know.
Many investigators and officials involved in the flight's disappearance have been cautious in pointing to a specific cause for the crash. However, Egyptian Civil Aviation Minister Sherif Fathi said the plane was more likely brought down in a terror attack rather than a technical malfunction.
No militant group has claimed responsibility for the attack. European security officials said the passenger manifest contained no names of people on terrorism watch lists, the Associated Press reported. EgyptAir has not verified the manifest, which was leaked online.
What about the victims?
The 66 people on the flight included 15 French, 30 Egyptians, two Iraqis, one Briton, one Kuwaiti, one Saudi, one Sudanese, one Chadian, one Portuguese, one Belgian, one Algerian and one Canadian, according to EgyptAir. Two babies were on board, officials said.
A plant manager with Cincinnati-based Proctor & Gamble was one of 66 passengers and crew members aboard EgyptAir Flight 804 when it disappeared Thursday over the Mediterranean Sea.
Others on board included a Welsh geologist, the sister-in-law of an Egyptian diplomat, a Kuwaiti economist and a French photographer who, according to The York Times, covered rock concerts.
EgyptAir offered its "deepest sorrow" to family and friends of the passengers. It said airline officials met with relatives of the passengers and crew at a hotel near Cairo International Airport to inform them of the situation.
