“It’s the little things, like always saying, ‘My airplane’ or ‘your airplane’ when we transfer control, so there’s no doubt about who’s flying the airplane.”
It's the little things... if he didn't do that he'd be a completely unprofessional fool. Having actually been in the military, in a multi-crew aircraft we would not just say "your aircraft", we'd show the other guy our hands as a way to make sure he/she knew a transfer had occurred. Silly thing but true.
