It was the pinnacle of human engineering "by hand" - we would struggle to duplicate it today as many of the skills have been lost and people have different skill sets today (and so on). It should be heralded for its amazing achievement.Yes, I agree, there was a political component, it was a race of sorts with the Soviet Union, and part of the Cold War hostilities. Which makes it even more improbable that Kreml wouldn't have immediately exposed it as a hoax. They would have been gloating about it for ever.
It was if course also part of the incredible scientific leaps, made in the USA in a number of fields, during that era. Which makes me weep when I consider the USA at this moment.
