The discovered part was a meter-long and 65 centimeter-wide gray metal fragment. According to military experts, the object may be the engine cover of the helicopter-plane.series of aircraft crashes in Okinawa. The most recent incident involving the aircraft occurred in Okinawa on December 13, 2016, when an Osprey crashed off the coast of the prefecture during refueling exercises. The wreckage of the plane was found in water.
Following the incident, Osprey flights over the densely populated city of Ginowan were suspended but were resumed a few days after.
