The Marine, whose identity has not been released, disappeared during a routine training mission at about 6:30 p.m. Monday. He is believed to have fallen about 45 miles west of Marine Corps Air Station New River in Bladen County.
He was attached to the 2nd Marine Aircraft Wing and was part of the crew on an MV-22B Osprey. The Osprey, a tilt-rotor aircraft, is designed to take off and land like a helicopter while flying like a plane.
Military officials said the circumstances of the fall are under investigation.
