I too am interested in investigating and persuing an ATCO career.
It seems a good thing to go and visit a facility to get a bit more of an insight.
Which facilities are best? regional a/p like say gloucestershire airport or somewhere a little bigger and busier? what about en-route centers, is it possible to visit those?
Who supplies the ATC services at airports? is it a mixture of private companies like NATS. Reading the above replies it seems some airports train their own, so, who are they regulated by?
I come from the midlands (cheltenham area but now in staffordshire at Uni) so are there any facilities where a young hopeful might be more likely to be welcome?
Ok that'll do

im sorry that these must be questions that are repeated over and over in this forum.
Any feed back whatsoever will be much appreciated
thanks
