On Twitter I found this map overlay site and I couldn't resist to copy/paste this URL to those of you who are interested in stuff like that.
You can use it to
- get locations of presently listed airports, bases and heliports throughout Russia, Belarus, Ukraine, Kazakhstan, Mongolia and Abkhasia.
- display NOTAMs regarding airspace closures and other oddities which could indicate air combat exercixes and/or scheduled (ballistic) missile launches
So it may be useful for scenario creation, ideas and of course following real life developments.

Only downside is the fight you might have with the cyrillic letters if you don't manage to have google translate (or similar tools) convert the site (I got it working on my android tablet only, no chance on my computer so far)
