A lot of history that was locked up for decades behind the Iron Curtain. I've long been curious about the Soviet Aerospace industry. When I was a squid, I had an older pilot tell me how tough it really was to beat some of the Soviet made jets in Vietnam. He also said you could tell when you were fighting Russian trained Chinese pilots....WAY more competent than Chinese rookies or the Vietnamese. (A lot of what we were told about this was just propaganda.) If you get past the political BS and make yourself look at it objectively, the Russians built some impressive air & spacecraft. (And vacuum tubes.
) Still do.
Cars, food & drink? Not so much.
