Most of my rocket-science knowledge is from Kerbal Space Program, which I also recommend to anyone with a passing interest in space :)

Unavailable for me in the UK, what's the name of the documentary?

"Cosmodrome".

Can't find it anywhere on the internet, not even Netflix here in my country. :(

I cannot access it as well, but it should be "Cosmodrome"

Excellent, thank you. There's a parallel between Sergei Korolev and Elon Musk, I believe.

To amplify just a bit - I watched the linked video. The parallel that struck me was the description of Korolev as an amazingly multitalented person. I regard Musk as a polymath as well. It interested me that these two chose work that requires understanding of many disciplines (fluid dynamics, combustion chemistry, materials science, control systems, etc.)and were so effective as individual contributors and as leaders.
