Museum of Yugoslav Aviation at the Belgrade Nikola Tesla Airport (BEG) looks very interesting. Larger planes seen here are Sud Aviation Caravelle, Iljushin IL-14, Junkers Ju 52 and Douglas DC-3. There are also group of Mig-21's, a Mig-23 and many Jugoslav-built Soko Galeb jet trainers. Inside the museum there are the remains of F-117 82-806 shot down on March 28, 1999, near Budjanovci, Serbia. Info link has many fine photographs of the exhibits.
