Is there an exchange plan where controllers from different countries can work in other country's air traffic control centers? Or I guess I should say at least observe.
I would imagine that a few day working in the New York City TRACON would open a few eyes for other countries controllers and the same with the London Center area control for US controllers.
I've flown in both, New York of course a lot more than London, but both have always impressed me with their professionalism.
Many other countries I flown in, which will go nameless, not so much.
