What happened
During a mission to perform radio direction finding, an aircraft traveling from Pleiku toward Huế was struck by enemy fire. The incident occurred approximately 40 km southeast of Saravane, causing the plane to crash. The wreckage of the aircraft remained undiscovered until October 1969.
All 10 crew members on board were killed in the accident. The flight was part of an ongoing operational mission when it was intercepted by hostile forces.
Findings
Investigations into the loss of the aircraft concluded that the primary reason for the crash was that the plane was shot down by enemy fire during its flight phase.
