Skittles - well said - again and again - the likes of aviators who can sit there and say" yes I know exactly where the wing tip is, yes I know exactly how far that ERJ tail is, Yes I know I got 4ft6in because the ERJ tail appears to be inside the line" is all bollocks! And misd-agin it was not "right in front of them".
If every time we think "it looks to close" and stop and ask for a wing walker then most US airports would grind to a halt.
