Exactly Joe. But the trouble is they can be dangerous.
For example, drop onto a child or fly into someone's face. A drone could presumably break a window or distract drivers. There seem to be some enormous ones available.

I watched a short programme last night about how a drone can pierce the fuselage of an aircraft, or even rupture the fuel tanks located in the wings.

I'm also wondering if there was more to this than they're actually telling us. Terrorists could after all have explosives mounted on the blooming things.
I know they sound fun and can understand the attraction, but I don't think they should be allowed to be sold.
