The Antonov An-12, a four-engined turboprop transport aircraft, was operated by the Soviet Air Force in support of the People's Movement for the Liberation of Angola (MPLA) during the Angolan Civil War. On November 25, 1985, while on a mission to deliver supplies and personnel, the aircraft was shot down near Menongue in the Cuando Cubango Province. This tragic event resulted in the loss of 21 lives, highlighting the intense and violent nature of the conflict in Angola at the time. The MPLA, aligned with the Soviet Union, was in a fierce struggle against UNITA (the National Union for the Total Independence of Angola), which received support from the United States and South Africa.

The Angolan Civil War, starting in 1975, created a complex battlefield characterized by foreign involvement and regional tensions. The downing of the Antonov An-12 exemplified the dangers faced by military aircraft in a hostile environment where antiaircraft technology was becoming increasingly sophisticated. The MPLA's reliance on Soviet airpower had been a critical component of its military strategy, and losing this aircraft represented not only a logistical setback but also a loss of personnel and morale.

In the aftermath of this event, both sides continued to escalate their military efforts, with the MPLA seeking to strengthen its air defenses and UNITA enhancing its guerilla tactics. The civil war would persist for many more years, fueled by geopolitical interests and internal divisions. The incident on this fateful day serves as a poignant reminder of the tragic human cost of war and the complexities involved in international military aid and intervention.
