For decades, this craft defined "helicopter". The huge one-piece bubble extends to the cabin deck, giving the craft a much more round-nosed look than the Lama/Alouettes it resembles.

When in military service, it was called the H-13 Sioux, and in its medical evacuation role it starred in the opening sequence of the television series M*A*S*H. Various models were produced from 1945 to 1974, and many were converted for special uses, including the Continental "El Tomcat" agricultural sprayer with a roll-bar cage cabin and a pointed nose replacing the Plexiglas bubble.
