As it happens, I am 2/3rds of the way through selection for Air Traffic Control. I went to visit MACC (Manchester Area Control Centre) and was plugged into an area controller and the approach controller. The skill and professionalism is out of this world.
I was also given a tour of the visual control room (the top of the tower). While I was up there, A 747 had to abort its take off, as a flock of birds flew across the runway. This is when I was told about this incident. Quite scary.
It was quite an eventful visit. When I was plugged into the area controller, the royal flight began to transit his airspace. All of a sudden concentration doubled. Special clearance and larger separation is provided to a royal flight. I could see the controller sweating a little.
