Many [many..many] moons ago, I had the "Best Job in the World" I was a "Runway Controller" at Manch. I cleared vehicles [tc] to cross the runway vehicles to "wander" around the airfield..for Petes sake, I even cleared the Airport boss [Gordon Sweetapple] to use the Faireys and Southern taxiways for "Go Cart Testing"
Then it was "discovered"
that I was working on the Air ATCOs license
So the post was "chopped"
Earlier, [before I was "promoted" into the job] an ATCA11 "Runway Controller"
had to have a "medical"
Why? If you were on the ATCOs licence
we aim to please. it keeps the cleaners happy
