Shuttleworth...
I think you are taking life a bit seriously... In fact, I have already had an eMail from an upcoming Conc PAX who would relish any "extra" experiences they could gain for the (considerable) money they have spent for a flight before she goes... And as they pointed out, the chance of an extra takeoff / landing (like this weeks Gander pit stop) - wow!
FYI - previously if Concorde had filed to get airborne that night, all would have been reseated on 747s ASAP. But of the 98 PAX, very few (maybe none?) wanted this option... Hence it went 18 hours late instead... And I still stand by my comment that another go in the lounge was surely enjoyed by most...
