I was lucky enough to fly on Concorde in 2002, when they were offering steep discounts to get passengers back after the crash in 2000. It was clear at the time that the service was totally uneconomic. The seats were comparable to economy (although service was champagne and caviar). I'll always cherish my memories of seeing the curvature of the Earth and the windows feeling hot to the touch (as well as my Concorde cufflinks).
