Interesting visitors in 3rd AFB Graff Ignatievo last week - two-ship MiG-29's from "101 ЛАЕ Витезови" from Serbia. They have performed, along with Bulgarian 29's missile launches at the Shabla shootong range at the Black Sea. Except for the two fighters Serbia has participated with various SAM sites, like last year. But this has been the first international trip for the Serbian 29's.
