I live on Champion Hill and have done for 9 years now. Air traffic noise has not been a problem here for the first of my eight years but since August 2007, I have noticed it as being a more or less continuous problem from about 6.00 am to 11.00 pm, which I find extremely unpleasant, so much so that I have begun to think about moving. It is my intention to complain to Heathrow and I suggest that anyone else who is concerned about this does too.
