What happened
During the Linebacker II military operation, an aircraft departed from U-Tapao NAS in Thailand. The flight was manned by a crew of six members. While operating over Hanoi, the plane was targeted and struck by an SA-2 surface-to-air missile.
Following the engagement, the crew managed to navigate away from the combat zone. However, as the aircraft reached airspace over Thailand, it suffered a significant loss of altitude. The flight ended in a crash located approximately 35 km east of Khon Kaen. The accident resulted in four fatalities and two survivors among the crew.
Findings
The investigation concluded that the destruction of the aircraft was the direct result of being hit by enemy surface-to-air missile fire during its mission over Vietnam.
