There is a list published of telephone numbers/contacts of ATC units, on these forums.
I am in the same posistion as you (as we've discussed), I e-mailed 3 people at both Edinburgh and Glasgow.
I got a positive reply from one of them, asking for further details. When I supplied those, no further contact was made.
I think I shall wait until closer to the time of work experience before I ask again. Don't want to badger
I will find that list, although I believe some of the numbers are for FLIGHT CREW only.
I would do as I done, establish e-mail communication, and then telephone.
I go flying later today, so I can suck up to them on the radio
EDIT: Here is the thread.
