They Control aircraft in un -controlled airspace and you say that is not incompetent!
Our G is not ICAO F as we are obsessed with mandated radio and mandated VFR radio calls in our G wheras in ICAO F no radio is required fo VFR.
Are you suggesting we should have a non radar tower such as Broome the same way as Plymouth- with ATC actually controlling aircraft in G?
And dimensions of about 3nm X 2000'.
