This reminds of the classic Heinlein story, Rocket Ship Galileo: https://en.wikipedia.org/wiki/Rocket_Ship_Galileo https://en.wikipedia.org/wiki/Rocket_Ship_Galileo I remember the plot was a little outlandish to me even when I 11 years old: All American kids team up with a brilliant scientist and build a rocket to the moon, where they discover and defeat a secret Nazi moon base.
