There were only 5 on the course, one was already allocated to EGFF, so everybody passed that started.
When I was on the ADC course, visits could be arranged for small groups to TC, but nobody took up the offer apart from one or two...the glamour was in visiting Heathrow.
When chosing my preferred choice, I requested Area - not necessarily because of the type of work, but because I didn't want to be posted somewhere I would rather not be. I was happy with any of the area centres, so for me the job was not the only aspect worth considering.
