We here in Aus take a "fly neighbourly" approach to our operations and take a very dim view indeed of those cowboys who choose to bring ill feeling toward our chosen profession/hobby. I think that xrdbear should be advised to post the rego of the machine involved and let the pilot defend his actions in front of his peers.
Whilst I agree with your sentiment, having flown in both UK and Australasia I can tell you they are two vastly different flying environments. As a military heli operator we 'fly neighbourly' as much as possible however when you take an island smaller than NZ and cram +60 million people on it, it becomes virtually impossible not to annoy someone! The MOD receive numerous low flying complaints each day and I myself have been accused at air shows and village fetes of 'flying so low you blew my hat right off!' and 'hovering in my back garden'. When faced all too often with these sorts of far fetched, exaggerated complaints it is understandable that heli operators are sometimes a little reluctant to believe claims from members of the general public.
In this instance however, one helicopter pilot may be rather fortunate that xrdbear was able to handle his complaint in such a mature manor.
