Lets get real
I have been alarmed as a member of the British Model Flying Association for about 50 years of the threat to our freedom of the skies these newcomers pose. Our membership has negotiated a good work around so we may continue our peaceful and responsible pursuance of the hobby, based on our flying tests etc. No doubt drone operating clubs would echo the sentiments and keep out of the way of man-carrying machines and their property. It isn't us you are after. Its the little ignoramuses who can get their hands on a sophisticated and easily operated bit of kit.
So why don't we insist they build in gps driven exclusion areas into all drones, whatever the weight. It can't be all that expensive if a number of them have 'return to base' switches and fantastic stabilisation computers already, can it? Such exclusion zones could also exclude prison airspace too, so excluding another antisocial use. ARTF models have been around for years now with little GA conflict but it is the advent of drones that has attracted the irresponsible and the lunatic fringe.
Sorry if this has already been said but it does seem a simple fix.
