And of course you never make a mistake in the cockpit.....do you
And by the way:
If there's any doubt when I taxi my aircraft, I get wing walkers out to give me a thumbs up for good clearance. Same should apply here. There's simply no excuse for driving things into a parked aircraft.
Of course plenty of people available for wing walkers, no pressure, no sudden retern of aircraft early, etc, etc.
Give them a break, as I said every body makes more mistakes.... theirs are just more visible than others. Therefore they get slaged off (normaly by people like you) more quickly.
