> I am not an American. But how many 78 year olds are working at missile defense companies as engineers? It kind of makes sense. A lot of military equipment is old. The front-line US land based nuclear missile entered service in the early 60s. If you got an old guy around from the early days, he might be valuable for filling in gaps in knowledge even if he's doing little else. Though I'd expect that military and defense contractors are a lot better at documenting important decisions and reasoning than the typical half-ass private corporation.
