On December 28, AirAsia's Airbus A320-200 departed from the Indonesian city of Surabaya, en route to Singapore, and lost contact with air traffic control. Less than an hour after the takeoff, the pilot of flight QZ8501 requested permission to change the route and altitude due to bad weather conditions.
Of 162 passengers and crew on the aircraft, 40 bodies have been recovered and 24 have been identified, the head of Indonesian search-and-rescue agency Bambang Soelistyo said at a news conference Wednesday.
