First flown in 1929, the Fizir FN was a successful Yugoslav training aircraft of which about 200 examples were built. During WWII production at the Zmaj factory in Axis-controlled Zemun, near Belgrade, continued for the Croatian air force. Some ten undelivered aircraft, including this one, were captured by Tito's forces in 1944. 9009 was used by the Yugoslav air force until 1947 and then by the national aero club as YU-CAY until around 1960. Prewar Yugoslav markings are carried.
This G4M - flying with VOC - is the only example of the modified G4 Super Galeb. It is easily recognizable by its sidewinder rails at the wing tips. During the 1999 war this aircraft was damaged by NATO bombs. After that is has been restored to flying condition.
