A Bell Boeing CV-22 Osprey of the US Air Force (USAF) has crashed in Japanese waters.

In a statement later on 29 November US Air Force Special Operations Command (AFSOC) said the CV-22B Osprey from the 353rd Special Operations Wing was involved in the “mishap”.

The aircraft was “performing a routine training mission off the shore of Yakushima Island, Japan, with eight airmen on board,” the AFSOC statement said, adding that the aircraft had taken off from Yokota Air Base.

In a press conference in Tokyo later on 29 November Japanese Parliamentary Vice-Minister of Defense Hiroyuki Miyazawa said the CV-22 “made an emergency water landing off the coast of Yakushima” at 1440 h local time. Clarifying his use of the term “emergency landing”, Miyazawa said the Ministry of Defense (MoD) had “received an explanation from the US side … that the pilots did their best [to control the aircraft] until the very end”.
