McDonnell Douglas, first made famous by the DC-3, later the DC series of commercial jets, there are still a lot of MD-80s flying out there. McDonnell Douglas also built military planes - and other defense products. My parents retired for the first time in their 50's, younger than I am now. After a year or so, they became restless, my father worried that he didn't have enough money, and they both went back to work. My mother worked retail for a few years, my father went to work for McDonnell Douglas in purchasing, buying parts in a plant the assembled cruise missiles. He worked there almost a decade, drew a small pension from them for the rest of his life.
Amazing the things that draw connections like this.
