Are they ignored or are they only ever going to be a statistic. Do you expect the airport to investigate every single moan and grumble that somebody can hear the vague noise of a plane? I too have lived under a flight path and, irrespective of it being linked to my financial income, the noise is rarely intrusive these days. I would assume "get a life" was a little tongue in cheek but maybe there is some truth in it - one persons complaints are another persons inane moans. People can rightly complain as much as they want, but there comes a point when the evidence against and the volume of pettiness mean it rightly becomes just another number in a table of MI for most and a discussion point for people with inane bees in their bonnets on internet forums.
