What happened
During the execution of the Linebacker II mission over North Vietnam, an aircraft operating out of U-Tapao NAS was intercepted while traversing the airspace above the Hanoi region. The aircraft, carrying a total of six crew members, was targeted by a North Vietnamese MiG-21 fighter. Following the engagement, the plane crashed within the Giáp Nhị district of Hanoi.
Of the six personnel on board, the incident resulted in two fatalities and four survivors. The surviving crew members were subsequently recovered 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 during an aerial engagement.
