When I started this thread I never expected the fantastic response it has received! Thanks people for contributing your memories and pix!
I've just been watching a documentary about Concorde and perhaps it's worth mentioning that what killed Concorde was not the crash (though that didn't help) or 9/11 (that didn't help either) but Airbus's unwillingness to maintain what was by then the oldest aircraft in BA or AFs fleets. Like all old aircraft, they needed more and more maintenance and Airbus weren't prepared to do it at what BA and AF considered a reasonable price. So the final death knoll was sounded by Airbus's accountants. What a sad way to go.
