What happened
During a bombing mission originating from Kadena Air Force Base, a B-50 Superfortress flying over North Korea encountered extreme weather conditions. While in flight, the aircraft entered an area of intense icing. The accumulation of ice led to a total loss of control, resulting in the plane crashing into mountainous terrain approximately 34 km southwest of Gangneung.
Of the twelve people on board, there were 11 fatalities and one survivor. The crew member who was successfully rescued was the only individual to escape the wreckage.
Findings
Investigations into the accident determined that the primary reason for the crash was excessive ice buildup on the wings during flight, which rendered the aircraft unmanageable.
