It works the other way too of course. I remember seeing a documentary on JFK controllers and was amazed at how anybody could understand what they were saying they were talking so fast, and I'm a native speaker! To be fair though all the pilots seemed to pick up everything on the first attempt and relayed it back to the controllers almost just as fast!
Credit to all you guys - both controllers and pilots, you make a complex job seem very easy to a mere enthusiast like myself!
