MiG-21PFM 5311 still wearing the dragon badge of 10PLM / Lask, but serving with 1PLM at Minsk-Mazowiecki. This type was known as 'Fishbed-F' and had limited operational capacities, due to only two weapon pylons present. The last sighting of 5311 was in December 1995 at the storage facility of Mierzecice.
