During the Cold War, the Soviet Union produced thousands upon thousands of fighter planes like the MiG series. Those planes don't last forever, and eventually each is taken out of active service. What to do with so many retired planes? One thing is to make monuments of them! See, a retired plane is a ready-made sculpture, and a tribute to Soviet power. These fighter plane monuments still stand all over former Warsaw Pact countries, in air fields, military bases, schools, town squares, and even apartment complexes. Urban Ghosts has pictures of 35 such monuments. Link
