AN2 Driver, you're right, I haven't considered it's in defense ministry ownership, the airplane, means - wasn't over-used, no regular flights, most likely - was idle most of the time. Even - more mysterious. These days, when Russian Ambassadors got shot out as turkey-s ! I mean - our ambassador in Istanbul, in art gallery opening - can be any thing! But then - as I understand - no one would "plot" mean things for the jet in Sochi - as the fuelling stop over there was un-planned? They changed fuelling location when already in air, because of weather conditions in Mozdok? Who'd "expect" them, in Sochi?
