So adding to the stress of a terrible financial and legal position is the unforseen noise issue, which my wife and I did everything reasonable before we moved in to avoid.
So you already had an objection to helicopter noise, above other noises. Or did you not? If so, what steps, i.e. "everything reasonable" did you take to avoid the noise problem? Or do you mean "did everything reasonable before we moved in to avoid" your financial and legal position?
I ask because you say this ongoing noise occurs every day and yet you also said that you spent many hours at the house before buying it. If so, the noise must have been apparent at the time and it must therefore have been obvious to you. The two statements just don't add up.
I sympathise with your situation to some extent; I would far rather you could enjoy your house without the noise which upsets you so much. However, you appear to want everyone else to magically change their very long standing behaviour and method of earning their living to suit your recent issues (you said you have recently bought the house).
Presumably you enjoy the use of local roads and motorways, which have been there for years. How would you feel if someone who recently moved in right next to one of those roads or motorways contacted you, called you names and then tried to persuade you not to drive past their house because they didn't like the noise from your car or motorcycle? It's precisely the same sort of thing.
Again, if you would confirm the area where you live those of us here could at least try to avoid it, if at all possible. If you don't, how can you expect anyone to do anything? Or do you really expect us to tell our customers that we can't fly them because their business trip isn't seen worthwhile or necessary by some bloke who's just moved into a house near Epsom?
What about your trip to work - is that worthwhile or necessary? What if an objector to your commuter or pleasure vehicle, be it car or motorcycle told you that if you're not driving a fire engine or ambulance, to stay off the roads? Why don't you go by bicycle or horse? What about the poisonous methanol fumes and the noise from your radio controlled helicopter - are they really necessary?
