BuzzBox,
As it so happens, I do have extensive experience of the US airspace system, including MOAs etc., in everything from light singles VFR through to somewhat larger aircraft, and a few in between, Porter has got it right, I rather suspect you are the one with limited experience, at least from the civil side.
It is so very sad that the blinkered thinking of those who have only flown in Australia, and believe that is the only ( or the normal/average) way, simply cannot comprehend the US approach, and the joy, the fun of flying in US ( and Canada, to give them their due) compared to Australia.
And do not forget, the US air safety outcomes are far superior to Australia, does this suggest they might just be doing something right ---- certainly more right than Australia, where freedom, in all of its manifestations, is increasingly circumscribed.
Tootle pip!!
