For reference, these rockets were far from perfect. They had a very different approach to design and safety. Construction/fabrication errors that today would never be allowed anywhere near a human-rated rocket were accepted and dealt with. It was a different time. https://www.wired.co.uk/article/f-1-moon-rocket https://www.wired.co.uk/article/f-1-moon-rocket "That's one thing we were trying to get knowledge on: what imperfections were OK to live with versus what imperfections are going to give us problems?" "Like with the injector," said Case, speaking of the 44-inch (1.1 metre) metal plate that spewed the propellant into the engine's nozzle. "There are hundreds of holes drilled into the main injector - all drilled by hand, too. And one of the holes you can actually see where the drill bit came down at the wrong spot, and the guy just stopped - you can see where he moved over to where the hole was supposed to be and finished drilling the hole. They kept that and would have flown with that engine. Those kinds of things were pretty neat."" https://airandspace.si.edu/collection-objects/injector-plate-rocket-engine-liquid-fuel-f-1-recovered/nasm_A20160018000 https://airandspace.si.edu/collection-objects/injector-plate...
