Description
The An-12 transport plane was engaged in a test flight at the Scientific Research Institute of Automatic Devices. An armored vehicle was equipped with a cargo drop system that included four parachutes. During the flight the rear cargo door was opened and the parachutes were released. They were supposed to pull out cargo but it unexpectedly jammed. The cargo turned around and became stuck. The moment all four parachutes deployed created an enormous drag, causing the cargo to work itself free, at the same time significantly destroying the rear fuselage. Under the influence of aerodynamic forces, the weakened structure began to collapse, as a result of which the tail section separated. The An-12 crashed into a field and exploded.
