That reminds me of an experiment done at CYYZ a couple of years ago. The airport has a curfew in effect (11pm-7am, if memory serves) and the operator, the Greater Toronto Airport Authority, wanted to find out if stage III takeoffs would upset the neighbours. They authorized a cargo carrier to take off every day an hour before the curfew lifted. For six months they received no complaints, but after a local paper reported the story they averaged 50 complaints a day.
