What happened
During the execution of the Linebacker II mission, an aircraft designated as Quilt 3 departed from Andersen AFB on Guam. The flight was part of a larger-scale operation targeting areas in Vietnam. While navigating the airspace over Hanoi, the aircraft was struck by an enemy SA-2 surface-to-air missile.
The impact resulted in the plane crashing within the Yên Viên region. Of the six crew members on board, there were two fatalities and four individuals who were subsequently captured and held as prisoners of war.
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.
