• The plane, an Airbus A320-200, was carrying 155 passengers (including 15 children and one infant) and seven crew members. The passenger total includes 149 Indonesians, three Koreans, one Singaporean, one British person, and one Malaysian.
• The plane lost contact with air traffic control somewhere between Kalimantan and Belitung island.

What we don't know

• What caused the accident. Right now, it's believed that weather played a role, as there were severe thunderstorms in the flight area. Indonesian transport officials said that before losing contact, the flight's pilot requested permission to take an alternate route to avoid storms, and also requested rise from 32,000 feet to 34,000 feet, but the plane never ascended.
• Where the main body of the aircraft is. Officials believe it's likely located on the ocean floor, which could help explain why no signals from the plane's Emergency Locator Transmitter have been detected.
