I also saw that particular aircraft, (but departing from SOF in the morning).
I also got that Balkan aircraft with the OM- registration, but then, I got arrested by the local 'police heros' here at SOF. With that aircraft I'll remember my last spotting trip to my home airport.
About arresting me is a long and interesting story, that I'll put in the photography forum later.
Sorry about the qualitym but the police took the film from my camera, but I also got a picture of LZ-TUG with my point&shoot Pentax camera.
