Radar tracking a missing Malaysia Airlines flight indicated that it may have turned back from its scheduled route to Beijing before disappearing, Reuters quoted Malaysian military officials as saying on Sunday. Malaysian rescue teams have expanded their search to the country's western coast. "What we have done is actually look into the recording on the radar that we have and we realised there is a possibility the aircraft did make a turnback," Rodzali Daud, the Royal Malaysian Air Force chief, told reporters at a news conference. The flight carrying 227 passengers and 12 crew was presumed to have crashed off the Vietnamese coast on Saturday, after losing contact with air traffic controllers off the eastern Malaysia coast.
