TU,
When I last saw the Captain saying goodbye I was getting off a Stratocruiser!
You might have to Google what they were but an early A380 with 2 decks! Nothing is new!
I know you can't do it these days and that times have changed.
In any case if it had been a less than perfect landing he (sorry it always was him then) spent his time saying that the other pilot had been at the controls!
Good Luck One & All!
