RIP Neil Armstrong.
Getting there and back was the easy part. There were engineers with slide rules to calc it, check it and recheck, hundreds of times, just to put a compact package on the moon.
This particular package contained men with bigger balls than anyone on the planet.
In 1969, most of the US population was focused on Apollo 11 without realizing how it came to be. The only reason we put a man on the moon was to scare the Soviets, and it worked. Brute force technology, just to prove a political point.
But that has nothing to do with the pure balls required by Neil Armstrong, Buzz Aldrin and Michael Collins (and the rest of NASA) to say “BITE THIS, KHRUSHCHEV! We’re Going To The Fuckin’ Moon – Because WE CAN!” and then have the balls to risk their own lives doing exactly that.
RIP Neil Armstrong.
