In 1952 during the Korean War, the US Army modified Bell H-13Bs by attaching stretchers to the tops of the skids, making them the first air ambulances for medical evacuation. In this medevac role, the Bell H-13 flew into battle and extracted wounded soldiers, drastically improving their chance for survival. The popular TV show M*A*S*H depicted the Bell H-13 “Sioux” in this important medevac role.

The Bell 47 is a helicopter of firsts: World’s first helicopter certified for civilian use (1947), first to be used by all branches of US Armed Forces, first to carry a US President, first to cross the Swiss Alps, first to be used as NASA’s lunar module training aid, first to be Batman’s “Batcopter,” and first to be a crop duster.
