Force,
I understand your point, and while I have only had the pleasure of visiting Europe once for two weeks, and Mexico once or twice too often, your point is well taken. All I'm trying to point out is that most U.S. Controllers are Federal Government employees, and some of us work quite closely with our military units over here. In fact, the U.S. military seems to slowly be getting out of the ATC business, and turning it over to civilian DOD and FAA controllers. As such, the Federal Govt is, for better or worse, very picky about who they hire, or even let visit our facilities nowadays. Paranoid is probably not too strong of a word. I just don't see that changing soon in our present political environment, that's all.
As I said in my original post,
Personally, it would be very interesting to work with some folks with different backrounds.
Thanks for your sentiments.
