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.

Russian Americans are Americans of full or partial Russian ancestry. The term can apply to recent Russian immigrants to the United States, as well as to those who settled in the 19th century Russian possessions in northwestern America. Russian Americans comprise the largest Eastern European and East Slavic population in the U.S., the second-largest Slavic population generally, the nineteenth-largest ancestry group overall, and the eleventh-largest from Europe.
