I've just had a nose around the area via Google Earth thanks to cargosales' excellent recce.
It makes me feel physically sick to think that anyone can be worried about residential noise.
I would have thought the noise from Heathrow's DVR and DET departures from 27L/R (which recently have gone on until 2330 local and are usually heavily laden 747s and A340s) would have made a lot more noise than a handful of concerned service families as they pass over the Epsom NDB nearby......
