What happened
During a nighttime intruder mission, the crew maintained radio contact until 21:13 local time. Shortly after this final communication, the aircraft was intercepted and struck by fire from a MiG fighter pilot. The impact resulted in the plane crashing within North Korean territory.
Following the incident, an extensive search was conducted, but no wreckage or evidence of the aircraft could be located. There were no survivors among the four crew members on board at the time of the disappearance.
Findings
Official investigations concluded that the loss of the aircraft was a direct result of being shot down by an enemy fighter during its mission.
