Watching part of the US ABC News this Sunday morning again had reports of Drones encroaching the Air space not only around but inside major airports (New York) and claims that several drones have missed contact with the aircraft by only a few metres.
One huge scare was when a drone was flown and landed on the dais directly in front of the German Chancellor (Merckel?) at a public meeting.
This incident of course has the security division for VIP's worried as how easy it would be to use one by anybody with harmful intent.
It will only need the killing of one Head of State or the attributable crash of a commercial aircraft caused by a drone and more than shit will hit the fan.
I know RC aircraft have existed for decades but these new versions appear not to require as much skill to fly as fixed wing aircraft do plus their small size and maneuverability makes them ideal for someone to use whose bent on doing harm to others.
