SQUAWKIDENT,
Where do you travel from when you fly away on holiday/business? Heathrow? Or do you do travel from another airfield and somehow feel better because you are part of the 'noise' that is perhaps irritating someone else ...... but not your home locale?
I'm willing to bet you don't arrange to be on flights that arrive/depart during daylight so as not to be disturbing someone elses sleep. No, like the vast majority of us you pick your flights for convenience and cost. Perhaps?
