I was lucky enough to win a Birmingham Evening Mail competition for a trip on Concorde, in1980. Manchester to Paris via mid Atlantic so we could briefly touch the magic Mach 2.0. Seating was about equivalent to economy plus. The passenger experience was not that spectacular, though I guess the acceleration on take off was noticeably larger.
It cost me a fair bit even though the flight was free. There was an overnight stay and having arrived by Concorde I felt I had to live up to the image!
It was a beautiful September evening, so I went to the Lido to see a show, had a meal on the Champs Elysée, and bought several souvenirs. Nearly missed my subsonic flight home as it was rescheduled an hour earlier. I got a phone call to my room saying if I were not at reception in 15 minutes it would go without me. I made it, but asked why I was not given greater notice. They said an announcement had been made in the bar during the evening. Astonishingly the other 99 passengers (who were all Chubb fire extinguisher salesmen) had spent the evening in the bar and had not left the hotel. And I thought my Civil Service colleagues were dull!
