I'm not biting at Winnie, god bless him, just posing a hypothetical.
I am led to believe the owner of a certain "airline" who doesn't like seeing his company named in these halls once failed a civil ATC course, thus explaining his lifetime hatred of ATC. (I am open to correction there.)
Although Winnie's own account of his successes indicate he is a cross between Weary Dunlop and Chuck Yeager, I wonder if his pathological hatred of Oz ATC could stem from the same source?
Just a thought.
