I recall the occasion when Concorde was due to do some crew training at Brize....
There were many complaints afterwards - because 'they' had cancelled the visit due to worries about noise complaints. As a result, 'they' received complaints from people who'd travelled from far and wide to see Concorde and had been disappointed when the session had been cancelled at short notice!
I also received a 'negative noise complaint' from the mayor of Cartoontown. One of her constituents had complained that one of our little flying club aircraft had flown over his house (at 1000ft agl) and he wanted the matter brought to her attention. Which it was - she basically told him to FOIFP and wrote to me to say how much she enjoyed seeing our little black aeroplanes pottering about overhead - so would I please ignore anything I heard from him in future!
