The Orteig Prize was a reward of $25,000 offered in 1919 by New York City hotel owner Raymond Orteig to the first Allied aviator, or aviators, to fly non-stop from New York City to Paris or vice versa. Several famous aviators made unsuccessful attempts at the New York–Paris flight before the relatively unknown American Charles Lindbergh won the prize in 1927 in his aircraft Spirit of St. Louis.

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.
