Japan’s Self Defense Force (JSDF) has cleared its V-22 Osprey fleet to return to flight after determining pilot error was the cause of an October accident on Yonaguni Island.
The US Air Force Osprey crash was also “Pilot Error”. That aircraft screamed for an hour to land and the pilot purposely ignored all warning lights and sounds, right up till the crash. I think the Osprey is safer than we have been trained to fly it.
