Would be nice if someone hired the 12VTAD regiment for a flight to Western Europe...
I wouldn't hold your breath too much. They are military aircraft ( despite Aeroflot titles) and are unlikely to get clearance as they are certified to military standards not civil.
Nice to get one at RIAT though, wonder if they have ever tried that??
Perhaps one of our more learned contributors can shed some light on flying foreign military aircraft in EU or UK airspace. I can recall German Noratlases or should it be Noratlii flying on DCN xxxx call signs widely interpreted as
Diplomatic
Clearance
Number.
Be lucky
