The only person I ever met who'd flown on the Concorde was the executive secretary for a startup CEO who had important meetings in Paris. Yes, this was a Dot Com.
I worked for a company that did those sort of things. It was bought by three crooks who then spent a ton of VC money on themselves. Porsches in the carpark and flights to New York on Concorde. Needless to say it didn't last long.
The only other person I know who flew on it was my wife (before we were married).
