Genies and bottles
I never thought that there was a topic that could attract more twats than Brexit - but some of the commentators on Radio 4 this morning..... - one suggested geofencing as a solution! Multiple incursions over 6 hours by multiple drones isn't little Johnny playing with an early Xmas present. It sounds deliberate. If it is deliberate then 'rules', jamming, blinding etc are all fairly pointless. The code to 'fly' a drone is in the GPL'd wild. The hardware costs pocket money. Drones can be autonomous (so no jamming, blinding) and disposable.
