Pat42 - wow, quite a post there, lots of information that will be useful to me in my stage 3 so thanks very much for that.
Lizplt - sorry I've taken a while, I've sent you a pm now. Good luck with your stage 3!
Regarding airport visits, I had an excellent tour around Manchester tower and ops room recently and thoroughly enjoyed it. I'd also like the opportunity to see the Liverpool tower if possible so does anyone have any contact details I might be able to try? Is it worth starting a new topic to ask?
Any help would be much appreciated,
Thanks
Peter.
