I think you misunderstand Ken. There are international treaties that define how aircraft operate. Russia is a signatory to these treaties yet choose to operate some military aircraft in ICAO regulated airspace without talking to ATC and without a transponder.
Hmmmmm. The Russians are operating in ICAO Class A airspace in this manner? Or another class?
Or more correctly, since we are talking about INTERNATIONAL airspace, are the Russians operating in violation of Annex 2? If so, what provisions of Annex 2 are the Russians allegedly violating? And finally, is Annex 2 even applicable to Russian military aircraft? How about US military aircraft?
