After the Soviet Union ceased production in 1956 of this two-seat advanced trainer/liaison aircraft/utility transport, it continued in Czechoslovakia, where it had been licensed to LET 3 with the designation C.11. An additional 707 Yak-11s were manufactured by LET and given the designation C-11. This one was on display in the static at this wonderful show.
A museum named OMAR Mine Museum (OMAR = Organization for Mine clearance and Afghan Rehabilitation), somewhere in Kabul city, showed me very unexpectedly a series of preserved aircraft. Several once Afghan Air Force aircraft and helicopters were kind of preserved, but the war in the country badly damaged the infrastructure of the museum as well as the aircraft. Luckily the whole was protected by a large wall, that prevented a possible even worse situation. The current status of the museum is unknown.
