Grave of Nikolai Nikolaevich Polikarpov, who designed the first fighter aircraft with retractable landing gear in the world (the pilot turned a crank to pull up or lower the wheels). His U-2 (Uchebnyy-2 -- Trainer-2) biplane, later called the Po-2, was still being used during the Korean War by "Bedcheck Charlie."
Mikhail Petrovich Simonov, aircraft designer who replaced Pavel Osipovich Sukhoi after the latter's death. Simonov was responsible for the design of the Su-27 (Flanker) fighter used today by Russia's air defense forces.
Mikhail Mikhailovich Gromov, the second man to fly non-stop across the North Pole from one continent to another. In this case from Moscow to San Jacinto, California. It was the longest non-stop flight in history up to that time. The year was 1937. A month earlier, Valeriy Chkalov had flown from Moscow to Vancouver, Washinton, non-stop across the Pole.
