What happened
During a mission serving as a cargo and support flight, a four-engine aircraft was destroyed while operating in the province of Cuanza Sul, Angola. The aircraft was intercepted and brought down by a SAM-7 surface-to-air missile launched by UNITA rebel forces.
The impact of the missile resulted in the total destruction of the aircraft. There were no survivors from the incident, as all four crew members perished during the crash.
Findings
Investigations into the destruction of the aircraft concluded that the primary factor was the use of a surface-to-air missile by insurgent forces. The deployment of a SAM-7 missile directly caused the loss of the aircraft and its entire crew.
