The KC-130 transport aircraft went down at about 4 p.m. local time in Leflore County, the Marine Corps Special Operations Command said Tuesday in a Facebook post.

Brig. Gen. Bradley S. James, commanding general, 4th Marine Aircraft Wing, Marine Forces Reserve, said Wednesday they were headed to El Centro, California, before going to Yuma.

"Indications are that something went wrong at cruise altitude," he said.
