Igor Sikorsky widened the field of aviation throughout his life with inventions that caught the interest of the world. In the early 1920’s, after successfully building a four-engine biplane, Sikorsky began his work on amphibian aircraft. The aircraft proved to be versatile with its ability to take off and land on an airstrip or in the water. Sikorsky increased the size and maximum range of his designs until producing the S-42 Flying Clipper. His line of amphibian planes became the precursor to commercial transoceanic flight. He played an important role in both the introduction of amphibian aircraft and its transition into commercial aviation. Sikorsky also contributed heavily to the development of the helicopter and research of rotary flight design. His design concept that had one main lifting rotor in combination with a smaller rotor to counteract torque is still used in modern helicopters. The helicopters maneuverability and ability to lift off vertically allowed it to fly into and out of terrain not fit for normal aircraft. He designed the R-4 which became widely produced and utilized by the military mainly for delivery of supplies and search and rescue. The company he began in New York, now called Sikorsky Aircraft, produced the S-70 Black Hawk helicopter in response to the Army’s need for a durable transport helicopter in 1972. Sikorsky Aircraft manufactured over 900 aircraft for the Army by the end of 1989 and a family of helicopters spawned from variations of the
