The prototype Djinn helicopter (SO-1220) was produced by the Sud-Ouest factory of the nationalized French aircraft industry and made its first flight in 1951. This aircraft was the world's first mass-produced jet helicopter, and it featured a "cold-jet" rotor that was turned by compressed air supplied by the engine with no further combustion occurring at the rotor tips. Five prototypes, and a pre-production series of 22, were built before full-scale production. In March, 1957 a Djinn set an altitude record of 27,860 ft.
