Igor Sikorsky

Igor Ivanovich Sikorsky was a Russian–American aviation pioneer in both helicopters and fixed-wing aircraft. His first success came with the S-2, the second aircraft of his design and construction. His fifth airplane, the S-5, won him national recognition and F.A.I. pilot's license number 64. His S-6-A received the highest award at the 1912 Moscow Aviation Exhibition, and in the fall of that year the aircraft won first prize for its young designer, builder and pilot in the military competition at Saint Petersburg.
