Rescuers scoured the sea for an AirAsia plane carrying 162 people which went missing in bad weather Sunday en route from Indonesia to Singapore, the third crisis for a Malaysian carrier this year. Air traffic controllers lost contact with the Airbus A320-200 around an hour after it left Juanda international airport at Surabaya in east Java, at 5:20am. It was scheduled to arrive in Singapore at 8:30am (0030 GMT). Shortly before disappearing, the plane asked permission from Jakarta air traffic control to track away from its flight plan and climb above bad weather in an area noted for severe thunderstorms. The pilots requested "deviation due to enroute weather before communication with the aircraft was lost while it was still under the control of the Indonesian Air Traffic Control (ATC)", AirAsia said in a statement on its Facebook page.
