What happened
During a mission targeting a bridge crossing the Yalu River between Sinuiju and Andong, North Korea, the aircraft was intercepted and engaged by a Soviet MiG-15. During the combat encounter, the aircraft's first engine ignited. Following the fire, the plane descended into the sea near Ryongampo.
Search efforts located minimal wreckage along the coastline; however, the mission resulted in 12 fatalities, as no members of the crew were recovered from the site.
Findings
Investigation of the event concluded that the primary reason for the loss of the aircraft was that it was shot down by a Soviet fighter during its attack run on the bridge infrastructure.
