You know, before Trump and the rise of neo-nazism into the mainstream I used to be huge into interwar media (early talkies, silent films, radio, etc) and one thing I found was a sci-fi radio show (I am not sure if it was Buck Rogers or Flash Gordon or something else) that seemed to treat the very concept of making into space in the 20th century as an impossible concept.

But a little over 20 years after that broadcast Sputnik happened. So many listeners and writers of the time absolutely were eating their own words afterward.
