seams to be like the Noise complainers, funny how the noise complaint numbers drop off to non existent during the night when you cant see the aircraft.
a recently wrapped up case down the south coast was the Jaspers Brush action group effort to have the airfield shut down on noise issues, so, the council, and the action group agreed on independent noise assessments being done randomly over the period of a few months,
The aircraft noise reading couldnt be taken over the noise of the motorway, and railway lines. and when traffic, or no trains were passing, no noise registered above the background noise.
seamed to be more a visual issue..
