The Bulgarian International Aviation Festival (BIAF 2011) dedicated to the 100 Years Anniversary of the Bulgarian Aviation! The true star of an air show leaves Krumovo airbase.
I was happy to photograph the flying MiG-21! MiG-21bis (Izdeliye 75B; NATO "Fishbed-N") in Bulgaria and East Germany these were designated MiG-21bis-SAU (SAU referring to Sistema Avtomaticheskovo Upravleniya - "Automatic Control System").
I thank Ivan Voukadinov for assistance to me.
