Several years back I knew an engineer who’d been at Lockheed and then came to work at Boeing defense. We were sitting around drinking one night and I asked him what he knew about a certain classified program I was vaguely aware of. It was like he was electrocuted - yells, “I don’t know you! I don’t know you!”, and literally runs away. I think he thought I was a Boeing or DOD security guy looking for blabber mouths. I guess my hunch was right.
They didn’t train him very well.
