Rick on Pawn Stars was offered a de-militarized fighter plane from the former Soviet Bloc. Apparently they are more common than we might realize.
Yep. Mig 15's, for example, are very popular since the engine is a direct copy of a Rolls Royce engine that you can still get parts for.
It used to be difficult to get a MIGs in the country. I remember years ago some guys in Wisconsin tried to import a MIG-21. U.S. Customs said no way. Now, there are a couple of privately owned MIG-29s flying.
This type aircraft has been in use in the US for quite some time. There is even a jet class in air racing now.
Other models in use include the L-29 Delfin, L-39, L-59 and TS-11 Iskra.
