This lovely plane really was '0612' with the Czechoslovak Air Force and was used for pilot training at the High Military Aviation School in Košice and then, after retirement in 1970, the aircraft was used by the aeroclub in Prievidza. In 2011 it underwent a major restoration to airworthy status and is now based at Točná.
This Czech-built CS-102 actually flew for the Polish AF as '266' and was modified to a SBLim-2 version before being sold to an owner in the USA in 1994 and registered N41125. It was bought by Czech Flying Legends in 2014 and returned to airworthy condition. It is pictured here landing on rw22 after a super display at NATO Days 2019. Note the real Czechoslovak AF Midget '2514' was cn 922514.
A Spitfire in Czech markings? Yes, Britain supplied 54 Spitfires to Czechoslovakia in 1945, including this aircraft. Following the 1948 communist takeover, SL633 went to Israel and on to Burma in 1954! Restored to airworthy condition in the USA, this must be the most cosmopolitan Spitfire around.
when Czechoslovakia split into the two sovereign states of the Czech Republic and Slovakia, this MiG-21 was transferred to Slovakia. It never entered service and kept its former Czechoslovak markings. As such it is now preserved in the Piestany museum
