Ah - so the penny has dropped.
I'm not so much bothered about meeting a UAV in the sandpit. What bothers me is meeting a police UAV over Swindon en route to its base at ******* or a Predator on climbout from ******.
We've all seen the brilliant film clip of the UAV being taken out by an Airbus's wake turbulence. A UAV is only as good as the screen the 'pilot' is using. It by no means is as good as having a pilot on board looking around and given the eqipment and stores they carry, a mid-air could have interesting results to taxpayers below.
