The Bell 47 is a single-engine two-seat light helicopter that was designed and produced by Bell Aircraft Corporation in the United States. It was the first mass-produced helicopter and the first to be certified for civilian use. The Bell 47 was widely used for various purposes, such as aerial photography, crop dusting, medical evacuation, military training, and police work. The Bell 47 was also featured in many films and television shows, such as MASH, Whirlybirds, and Magnum P.I. The Bell 47 has a distinctive bubble-shaped canopy that provides excellent visibility for the pilot and the passenger. The helicopter is powered by a Lycoming O-435 engine that drives a two-blade main rotor and a two-blade tail rotor.
