In addition to the thread on rotorheads, occasionally we have the odd torch/laser shone at aircraft on App to 15 at BHX from the flats.
Again, a knock on the door sorts them out. Always denied until they are told it is on video and are asked if they they wanted to discuss the matter further!
I believe some scrote 'oop north has just received 100hrs community service from the magistrate for shining a laser at a helicopter. (Endangering an aircraft).
