Bronze-coloured Polish MiG-21
The Mikoyan-Gurevich MiG-21 (NATO reporting name "Fishbed") is a supersonic jet fighter aircraft, designed by the Mikoyan-Gurevich Design Bureau in the Soviet Union.
It was popularly nicknamed "ołówek" (English: pencil) by Polish pilots due to the shape of its fuselage.
Early versions are considered second-generation jet fighters, while later versions are considered to be third-generation jet fighters. Some 50 countries over four continents have flown the MiG-21, & it still serves many nations a half-century after its maiden flight.
The fighter made aviation records. At least by name, it is the most-produced supersonic jet aircraft in aviation history & the most-produced combat aircraft since the Korean War, & it had the longest production run of a combat aircraft (1959 to 1985 over all variants).
