Sikorski is in fact a Slavic (mainly Polish) name and was probably chosen to show incompetence of censors, especially considering that this name may be a hidden allusion to Igor Sikorsky, a Russian aircraft inventor who emigrated to the United States after the October Revolution of 1917 and designed the world's first helicopter there in 1939.
