Drone - NOT amateur radio

Last night we had a drone above our house. I think it was taking photos of "our" windmill next door. I have mixed feelings about drones. They allow some very good photos and videos to be taken, but their uncontrolled use could be dangerous. Personally, I am in favour of some sort of licence.

UPDATE 0840z: Apparently the drone was inspecting the windmill sails (next door) to make sure they are safe.
