What happened
During a mission targeting the Anju Marshaling Yard, a B-29 Superfortress came under heavy fire from MiG-15 fighters just before its payload was released. Following the bomb release, the aircraft remained under attack and began to lose altitude. As the plane crossed the Taedong River near Chinnampo, the flight commander notified the crew that the third engine had caught fire.
In an attempt to save the remaining personnel, 12 of the 13 crew members successfully exited the aircraft via parachute. The burning bomber continued its flight path toward friendly territory, accompanied by US Air Force fighter escorts. Despite these efforts, the aircraft's descent continued until it impacted a mountainside and underwent a mid-air explosion.
Findings
Investigations into the loss of the aircraft determined that the primary factor was enemy interceptor fire which caused significant damage to the engines and subsequent loss of control.
