Both are honorable professions, but one should never confuse one for the other, even if your language does.
Our language? We gave you a perfectly good language, Nick; and just look what "your lot over there" did to it.
Totally agree, though but as far as keeping us flying it's far better to have a hangar full of mechanics than engineers. Keep the engineer away from the spanners, in the office by the phone. Then if he gets a difficult question he's covered both ways; he can either phone a friend or go into the hangar and ask a mechanic.
Notice that I'm doing my bit for international relations; I did call them mechanics for our transatlantic cousins. We all know they are "ginger beers" really though.
