Blame culture
Already the perfect pilots on the forum are blaming some one for this inccident, undoubtedly the B737 crew are not to blame fot this as they were stopped with the park brake set.
A number of misconseptions and time pressure led the Captain of the Air Atlanta B767 to misjudge the clearance or lack of it and remember he can't see the wing tip.
The whole thing was a bit of a storm in a tea cup but one thing that I can't understand is why modern aircraft are not fitted with lights in the wing tip that point at the ground the Lockheed Electra had them and it was a great aid to judging the path of the wing tip over the ground.
