Bonkers. I learnt to fly rotary at Denham 20 years ago with Heliair. It certainly wasn't a case of start small and see if anybody complains.
One commentator in the local press said he lived near the M25 so could they close it for all but two 15 minute sessions a week too?
The fact that anybody is stupid enough to buy a (cheap) house near noise pollution and then complain is bad enough. To take it to court and win is beyond insane. How is this any different to the hundreds of houses on the North Circular or A40? If anything, their owners would have a better case for increased noise over the years as the roads have become busier.
If Denham can't afford the appeal or do appeal and lose, the floodgates are well and truly open for so many more ridiculous claims.
