When he was in the air force, dad worked in fuel cells. After he got out, he worked as an auto mechanic for several years. Then he got a job doing structures work (body work) for Raytheon/Virtex/L3 Com (got bought out a few times and changed names). Then he applied as a general mechanic for Northrop. They hired him as electrician, trained him as an electrician and machinist, and now he's back to doing mostly structures.
