Aberporth base in West Wales is drone research centre. I think mainly military use but not sure.
They are potentially a good thing if used properly. Our local police were starting to look at them to reduce expensive helicopter deployment. Why send a helicopter to photograph an RTC scene when a drone could be deployed from the scene? Big ££££ saving. Also a less obvious spy in the sky for critical scenes ( hostage, siege etc).
We were being updated re this and one key factor was licensing the controller to go out of line of sight. There is a regulation of staying within sight/ distance limits and homing ability due to battery drain.
