I would never go that far and call London's ATC "the best of the world"! There is no "best of the world". I would place them into the category "among the best of the world". Don't forget busy airports and airspaces with excellent ATC like Frankfurt, Munich, Zurich, Geneva, Copenhagen, Amsterdam etc.. They are all in the same group as London/UK. And, Retard, possibly you have been put at the end of the queue because of your limited command of the English language (to protect other pilots/planes) or, you just thought that you were put at the end of the queue, because you did not understand it better. After all I do not believe that you are a real airline pilot.
