The presence of police at every airfield within a tank of gas range of London is a deterrent.
Excellent and well thought out. That would be ALL airfields, private strips etc in the UK - including Ireland [North and South - never mind the continent or Channel Islands] all of which is a tank of gas away from London - for certain types of aircraft albeit fixed wing, say P68. The 'reader' plan sounds reasonable at first glance but given the fact that most pilots cannot use a damn wiz wheel adequately I feel it may not work. As for police at each airfield?
Just what colour is the sky where you are??

Keep on dreaming buddy, better to do that than accept reality.
