I thought a good landing was where everyone walked away from the aircraft and an excellent one was where the aircraft could be flown again without being repaired........
Funnily enough, one of the smoothest landings I've had for some time was an BA A319 into ARN a month or so ago, with gusty winds and lots of bouncing around on the approach. I expected a solid landing and it was as smooth as you could wish, despite the winds.
I guess it those sort of occasions that make you realise why pilots are worth what they're paid!
