Sorry, Dan. I have no reason to doubt the ability or appropriateness of the people operating the radio at Redhill - or anywhere else in the UK, for that matter. It doesn't alter the fact that Redhill is not a controlled aerodrome, so that anyone operating their radio cannot ever be called a controller - there being nothing to "control". This is the kind of confusion that I so loathe in UK radio usage, and in UK aviation language in general.
