We get extremely busy at The Rat at times, despite the number of aircraft operating there, personally, I don't think it requires a tower. It's just the bull**** song and dance about 'numbers' that irritate me. The movements tend to be clustered. When it comes down to it, the cultural emphasis on self separation is relying on radio calls to sort it all out, the anality of radio call perfection distracts from looking out the effing window and missing aircraft. Most of the time the aircraft is not in the position it states it's in, but the call sounded awesome and the content was complete.
