Death flights () are a form of extrajudicial killing practiced by military forces in possession of aircraft: victims are dropped to their death from airplanes or helicopters into oceans, large rivers or even mountains. Death flights have been carried out in a number of internal conflicts, including by France during the 1947 Malagasy Uprising and the 1957 Battle of Algiers, and by the junta dictatorship during the Argentine Dirty War between 1976 and 1983. During the Bougainville conflict PNGDF helicopters were used to dispose of corpses that had died under torture, and in some cases, still living victims.
