The Skyvan is a twin-engined all-metal, high-wing monoplane, with a braced, high aspect ratio wing, and an unpressurised, square-section fuselage with twin fins and rudders. It was popular with freight operators compared to other small aircraft because of its large rear door for loading and unloading freight. Its fuselage resembles the shape of a railroad boxcar for simplicity and efficiency. Skyvans served widely in both military and civilian operations, and the type remained in service in 2009 with a number of civilian operators, and in military service in Guyana and Oman. Skyvans were used during the infamous death flights at the depths of Argentina's Dirty War in 1977, during which around 4,400 detainees were thrown to their deaths onto the Río de la Plata.
