Sikorsky (1889-1972) is synonymous with the successful development of three important types of modern aircraft: the large four-engine airplane, the giant flying boat, and the unique and versatile helicopter, each of which has played a vital role in the development of aviation.

During WWI, he built a series of four-engine bombers.

In 1927, Sikorsky built a series of amphibians used to pioneer Central and South America air routes.

In 1931, Sikorsky designed and built flying boats called “Clippers” for transoceanic air routes.

On Sept. 14, 1939, Sikorsky flew his design of a single-rotor helicopter after he changed the angle of the lifting rotor blades as they revolve enabling it to leave the ground.

Yanks exhibits a number of Sikorsky aircraft, including the CH-3, HH-52, R-4 and the H-34.
