HANOI - Vietnamese authorities are looking for a missing jet fighter that lost contact while it was flying on a training mission off the country's coastline on Tuesday, a senior army officer said. The Russian-made SU-30MK2 was carrying two pilots when it disappeared from radar around 26 nautical miles from northern Nghe An province, state-media reported. "We are looking for it and have no further information yet," Vo Van Tuan, the Vietnamese army's vice commander in chief, told AFP.
