There was a case in England a few years ago where a bunch of airport noise whingers were almost successful in getting a small airfield closed down. A smart lawyer then addressed their meeting at council chambers and advised them that their names had been noted and when a member of the group advertised his/her house for sale, they would be forced to declare to any buyer that aircraft noise or crash danger was the reason for selling. Of course this would scare away prospective buyers. The noise complaints soon faded away.
