A knee-jerk denialist over at The Flat Earth forum is making noises about Kennedy's speech referring to "new metal alloys, some of which have not yet been invented", snorting with disbelief that Kennedy was proposing to build a rocket out of imaginary materials.
While I can find lots of new things invented as a result of Apollo, I can't find any reference to new metal alloys
I think it was speech-writer's hyperbole, but does anyone have any ideas?
