WASHINGTON/TOKYO—Six U.S. Marines were missing following a still-unexplained mishap off the coast of Japan on Dec. 6 involving two U.S. Marine Corps aircraft, which may have collided mid-air during a refueling exercise gone wrong, U.S. officials said.
Japan’s defense ministry said that its maritime forces had so far rescued one of the seven Marines who were aboard the two aircraft at the time of the incident. Search and rescue efforts were ongoing, U.S. and Japanese officials said.
