I remember as a child seeing a documentary about one of the most idiotic projects that the Nazis did:
Some of their senior leadership so firmly believed the Hollow Earth theory that they set up a V2 launcher on a South Pacific island with a view of slingshotting missiles around the Sun and landing them anywhere in Europe or America. It turns out the Sun isn't in the middle of the Earth (who knew?!?) so this didn't work.
It came to mind because another government seems to have a similar attitude to science at the moment.
I can find no online references to this at all. Did the documentary maker make the whole thing up? Did I dream the documentary?
