Attack and System Failures
During a bombing mission over Taechon Airport in North Korea, the bomber was engaged by two or three MiG fighter aircraft at 1517 local time. The attack caused the failure of engine number one and a loss of the hydraulic system. Despite the damage, the pilot managed to steer the aircraft away from the combat area.
Crew Abandonment and Rescue
Eventually, all 12 crew members abandoned the bomber. The aircraft subsequently crashed into the Yellow Sea. All 12 occupants were rescued, though two of them sustained wounds. The aircraft was lost in the incident.
Official Findings
The probable cause of the loss, as determined by the official investigation, was that the bomber was shot down by enemy fighter aircraft.
