I am sure your nice part of Surrey does suffer from noise pollution and operators will take any REASONABLE precautions to try to alleviate your issues. Having said that to place the helicopters in the same category as motorbikes and toy helicopters weakens your position somewhat.
I never placed them in the same catagory, all I said was that I was into bikes and toy helicopters.
Have you ever tried to contact the operators responsible for a helicopter flying directly over your house? Without the registration number it is impossible, and getting the reg number is impossible if directly overhead, few helis have it on the bottom.
This is why it is so frustrating, nobody will listen to your complaint and at least say "we have listened but consider you needs less than ours" or something. All I get is buck passing......
