Am I missing something here?
90% of the air above us is radar controlled and anyone with suitable kit and license can fly through it and be steered so that they never come within 5 miles of anyone else.
10% is left for the citizens of the country to enjoy, bimbling about if they so wish, talking to no-one, non-radio even, just employing good old fashioned airmanship and taking responsibility for their own separation from hard stuff and others.
Someone, with good kit and license decides to take a very fast, very large, very unwieldy aircraft through the 10% bit and there are howls of disapproval if the aforementioned citizens do not immediately land or scatter to the other end of the country.
Just who is the muppet here?
