The Mark 3 implosion bomb was, in Oppenheimer’s words, a “haywire contraption,” difficult and dangerous to assemble. But at least some of the scientists in Los Alamos still knew how to make one. Nobody had bothered to save all the technical drawings necessary for building another Little Boy, the uranium-based, gun-type bomb dropped on Hiroshima. The exact configuration of the various parts had never been recorded on paper—an oversight that, amid the current shortage of plutonium, created some unease.
This reminds me of most of the services at Amazon -- less lethal, but also completely undocumented.
