1300 miles and lucky enough not to talk to ATC... believe me.. that's as safe as it gets... stay a couple of hundred feet high/low... a mile or two right of tack.. broadcast on 126.9... avoid the build ups... you have TCAS... if ATC start giving you cr#p about what to do...talk to the Russian a/c directly... don't believe anything he tells you... and work around him... welcome to the dark continent...
