Jakarta, Indonesia (CNN)—Before AirAsia Flight 8501 crashed, the co-pilot was flying the plane as the more experienced pilot monitored the flight. And things may have gone wrong in a span of just three minutes and 20 seconds, triggering a stall warning that sounded until it crashed into the Java Sea.
Those are the new details released by the Indonesia's National Transportation Safety Committee in a news conference Thursday.
Though it's common for the co-pilot to be in control of the aircraft, significant questions still linger over the crash of the AirAsia jet. Why did the plane start a sudden, steep ascent? Was bad weather a factor?
QZ8501 crashed December 28 as it flew from the Indonesian city of Surabaya toward Singapore. There were 162 people on board.
