Ryabtsev Boris Ivanovich (1927–1964) — pilot, Hero of the Soviet Union. Killed in the line of duty.
Ryabtsev Street (formerly Kazachikha-Knyazhikha, Voroshilova) — located in Moskovsky District, perpendicular to Moscow Highway. Runs alongside the Sokol plant from the viaduct to the turn onto Geroya Davydova Street. Parallel to Krasnykh Zor Street.
The street belongs to the Aviation Settlement and consists mainly of 2–5 storey buildings constructed in the 1950s–1970s. As a thoroughfare linking Moscow Highway with Sormovo, it is frequently cited as an example of an exceptionally good road surface. This is offset, however, by its narrowness (2 lanes).
An unsuspecting tourist who wanders in may get the impression of a back-alley passage between major hubs: numerous small shops, cars, and people. Here you will find the Sportkultttovary shop, famous well beyond the district, along with the second entrance gate of the Sokol plant and the Moskovsky District tax inspectorate, which expands a little more every year. No other points of interest have appeared so far.
