When I was a student I had a summer job with a firm that was resurfacing the southern runway at heathrow - at night obviously. We were 'housed' in a bunch of static caravans about 10 miles or so from the airport pretty much directly under the flight path. So I'd get home just about in time to hear the planes starting to use the runway again. After a few days I got used to the 'normal' planes but never got used to concorde gong past, around 10AM if I recall - like newboy says it shook the hell out of everything and was LOUD. That was then me up for the day.
