This thread is becoming difficult and obsessed with language, and which particular box of tricks is where and what the USSR normally 'do'.
It is very difficult trying to explain to people whose skills lie outside aviation/flying - in translation/knowledge of Russian procedures perhaps - that it is easily possible to land an a/c at an airfield, even in bad weather, with no contact at all with any ground control - yes, even in Russia - providing both the ground beacons and a/c systems allow, which we believe they did.
