Retired hardware engineer. Hey, here's my claim to fame: When I worked at Boeing I worked as a manufacturing engineer and I seldom saw anything I had built. One time I went up to the develpmental lab to see what this Fire Control box was. It had five incandescent indicator lights. Below each light was a toggle switch and between each light and it's corresponding toggle switch were stenciled the words "Missile Away". This was for the most powerful nuclear missile in the world. There were others who worked on this project and one of them spelled missile 'missle'. OMG, this guy worked on a nuclear missile and couldn't even spell it. You'd think you'd want to be accurate about details regarding a nuclear weapon.
