Search and rescue efforts were underway off Japan after two U.S. Marine Corps aircraft crashed in a still-unexplained mishap, leaving seven U.S. military personnel missing, U.S. officials told Reuters on Wednesday.
The Marine Corps offered little information in a statement about the incident, which occurred at 2 a.m. on Thursday in Japan.
The aircraft had launched from Marine Corps Air Station Iwakuni and were conducting regularly scheduled training when there was a "mishap," the Marine Corps said.
A U.S. official, speaking on condition of anonymity, said one of the aircraft was an F/A 18 fighter jet, while the other was a KC-130 refueling aircraft, with a combined total of seven personnel aboard.
