My dad was always a "If you got up there on your own, you can get down on your own" sort of man. Fantastic father. Terrible air traffic controller.

In my MG days, one of the concours regulars was an air traffic controller, and a busy airport. There were odd occasions when I would need to call him, and it was OK to call him at work.
What was un-nerving was that I could hear the comms going on in the background, and he would flip from me to some plane and back.......crackle crackle "level off at x feet, heading x degrees".....crackle crackle.....yeah so where were we?......................
Absolutely true story. He's retired by the way.
