Igor Sikorsky had experimented with helicopters in 1909 and 1910 in his native Russia. He immigrated to the United States in 1919 and founded Sikorsky Aircraft Company in 1923. In 1939 he returned to the helicopters that he loved and designed and built his first successful, and America's first practical helicopter, the VS-300. Igor Sikorsky himself, wearing a topcoat and fedora, piloted the VS-300 for its maiden flight test, powered by this exact engine on September 14, 1939 with the first untethered flight on May 13, 1940.
