Search and rescue operations were underway off the Japanese coast early Thursday local time after a Marine Corps C-130 and F/A-18 fighter jet crashed, and so far one Marine has been rescued, military officials said in a news release.

The rescued Marine is being evaluated by medical personnel at Marine Corps Air Station Iwakuni, Japan, while the search continues for the remaining six Marines involved in the crash.

The mishap occurred at about 2 a.m. local time Thursday, after the aircraft had taken off from Marine Corps Air Station Iwakuni to conduct regularly scheduled training.

Japanese search and rescue aircraft were aiding in the recovery, according to a Marine Corps statement.

“The circumstances of the mishap are currently under investigation,” the release states. “There is no additional information available at this time.”

While the exact aircraft involved were not immediately released, Marine Aerial Refueler Squadron 152 flies the KC-130J out of Iwakuni and several fighter squadrons are based there as well, according to the command’s website.
