Hi
I'm one of the FISOs at Barton and was probably in the tower when you came around yesterday.
TDM is pretty close re his estimation of salary, it's slightly more than that I think. For me it's a part time job which I do because I enjoy it - and because it helps fund my flying habit(!). everyone else is Full Time. I have a career in the week which pays the mortgage etc etc.
HD - We don't have any ex-ATCOs at Barton currently, although I believe this pretty common elsewhere.
