Sikorsky UH-19B Chickasaw helicopter walk around

Among the most successful of the early helicopters, Sikorsky's H-19/S-55 helped move the helicopter from being a potentially useful curiosity to an accepted way of moving men and light payloads around battle zones, helping to pioneer the air mobility concept.

The H-19 design built on Sikorsky's H-18/HO5S experience, but was considerably larger and more powerful; importantly, the engine (a Wright R-1300) was moved to the nose and the crew compartment relocated upwards, allowing a relatively large cargo compartment with sufficient room for ten passengers.
