Re Beeker
Had the fortune to meet an airline crew down route somewhere who some worked with a captain (the guy named "Beeker"), they were surprised when we said "oh you mean Beeker", to which we had to explain. They of course promised it would be updated back at their base soonest. So he probably is still asking not to be called Beeker now.
We had a crewman who was called "Gimlet" a small boring tool.
