Interesting. I visited Russia (Ekaterinburg) for the first time in July last and the Finnair flight flew south of both the main airport and the GA field (Uktas),
The aircraft then turned to make its approach over what looked like a military facility - watchtowers, high fencing and railway lines into long thin sheds. We were very low and right over it and I was strongly tempted to take a few pictures as the Russian military has always interested me but thought better of it in case someone saw me. I did some digging around when I got back and figured this must have been Kosulino-1 which is for railborne either MRBMs or ICBMs. It was also the site where Gary Powers was shot down from. Knowing the Russian mania for security I didn't fancy an extended stay there. With Satellite imagery I don't know why they bother with all these restrictions.
