“Man in Space” is an episode of the American television series Disneyland which originally aired on March 9, 1955. It was directed by Disney animator Ward Kimball. This Disneyland episode (set in Tomorrowland), was narrated partly by Kimball and also by such scientists Willy Ley, Heinz Haber, and Wernher von Braun, as well as Dick Tufeld of Lost in Space fame.
Shown on national TV in the US, you can see why rockets became all the rage in all types of design. This was about 6 years before Yuri Gagarin and Alan Shepard made it into space so there’s a lot of prediction and guessing still at this stage. Fun stuff!
