Morty; Everything was actually a combination of contractors. My Brother worked at Aerojet, North American, Rocketdyne, TRW, and Martin, working on lunar ascent engine, that “Canadian” arm on the shuttle, Saturn Five main engine seals, Titan, and various projects over the years. HIs “job swaps” were often to follow a project (and the money!), not single employers.
