Localresident - first of all I was very pleased to read that you enjoyed your flying, I'm sure that relations between 'them and us' would be much easier if people understood what light aircraft flying is all about by having the chance to experience it themselves.
The vast majority of pilots do everything they can to minimise any noise nuisance to those on the ground and where it is safe to do so aircraft are routed away from habitation.
With quieter, more fuel efficient aircraft gradually entering the light aircraft fleet, most of us expect the situation to improve over the coming years, so the chances of spilling your drink will be significantly reduced!
