Guys,
Instead of just (a)trying to justify the reason for the helicopter being there in the first place or worse (b)accusing everybody who doesn't enjoy the sound of whirling wings trying to smash into each other of being a NIMBY, why not simply answer the entirely reasonable question? Is there an exercise going on? Is the weather limiting the normal playground? Has someone painted 'Piss off Biggles' on a local barn?
All of these might be valid reasons and would answer Pandora's question (which, I believe, was written in just about as light-hearted way as possible). Just slagging a fellow pilot off because they don't enjoy their normal peace being interrupted, not once but six times, does nothing to further the reputation of the respondents.
