>>2473946>On 29 June 2000, the prototype H-4, registered JX0076, was on a test flight at the company plant in Matsumoto-City, Nagano. The pilot was hovering, when the H-4 was hit by a wind gust and contacted the building, 40 m (131 ft) to the northwest and then impacted the ground. The pilot was injured and the airframe damaged.Shocking. Who could have ever foreseen this bizarre twist of fate.
