Gry comes up with another sound point for nimbys to consider:
Motorsports.
(Should have thought of that one for myself coming from Enstone...)
The disadvantages of having an active licensed aerodrome in your back garden FAR outweigh the potential disaster that a disused aerodrome might become. Go-kart track, rally driving school, skid pan training, motorcycle school, motocross competitions...
Oh for the sound of a lycoming bimbling overhead!
Aerobatic Zone
This is a BAD idea.
Low level aerobatics down to 50' REDUCES the footprint of your sound polution.... thats no good at all.....
