The Marine Corps said Wednesday its tilt-rotor MV-22 Ospreys are safe to fly and resumed operations in Japan following a crash that killed three Marines last week.

The service put a two-day pause on operations while it examined the circumstances around the crash off the USS Bonhomme Richard during a training exercise in Australia, said Lt. Gen. Lawrence Nicholson, commander of the III Marine Expeditionary Force based in Okinawa.
