mmmm, firies working at aerodromes where they're likely to never put a fire out in a lifetime. Absolutely bloody ridiculous. I'm having trouble understanding how an ARFF facility can be justified when a tower isn't. And why there are towers at locations without ARFF? Not saying there should be, the whole thing is a massive wank.
Why shouldn't a firie provide a Unicom if they're going to be sitting on their arse waiting for that once in a lifetime fire. Why shouldn't they be doing ARO, or mowing the grass, or painting the gable markers?
