10090 Sikorsky           Discovered 1990 Oct. 13 by L. G. Karachkina and G. R. Kastel' at the Crimean Astrophysical Observatory.
Born in Russia, aircraft designer Igor' Ivanovich Sikorsky (1889-1972) built and flew the first multimotored airplanes. In 1919 he emigrated to the U.S. and created some 15 different types of aircraft. His helicopters were the first to fly across the Atlantic and Pacific oceans.
