I'm sure my mate ATCOII will shortly be in touch... but don't let it be known you want Heathrow or you'll get posted to Sumburgh!
Just a word of warning - they're all barking mad over there; I ought to know, I worked there for 23 years before being deported to West Drayton..
When you come to LTCC watch out for me - I'm the oldest Heathrow controller there; 3 days older than God at last count.
Good luck - honest!
