A passenger jet flying from Kuala Lumpur, Malaysia, to Beijing disappeared from radar and radio contact Friday afternoon at about 1:40 pm.
Almost three days later, no one has any clue what happened.
Here are the eight things you need to know about Malaysia Airlines Flight 370:
8. The overall consensus seems to be that the plane crashed, but where it went down and what caused it remain unknown.
7. The plane was in between Malaysia and Vietnam, traveling at a steady altitude of 35,000 feet when it vanished. It was scheduled to land four hours after it went missing.
6. Aboard the aircraft were 12 crew members and 227 passengers, two of whom are infants. The majority of the passengers, 160 to be exact, were from China.
5. The search operation has involved 34 airplanes and 40 ships from multiple countries to cover a 50-nautical mile radius. Among the countries assisting in the search are Australia, China, Singapore, France and the US.
4. Oil slicks, debris, a life raft and a door have been found in the ocean but all of them have been confirmed not to have come from the plane.
3. Possible causes for the crash include engine failure, explosion, terrorism, turbulence, pilot error or even pilot suicide.
2. Suspects of a possible hijacking are two passengers who boarded the plane using stolen passports belonging to two men from Italy and Austria. The suspects purchased their tickets together from South China Airlines using Thai currency.
1. A possible hijacking is also supported by the fact that, according to Malaysian officials, the plane may have changed direction before it disappeared.
