I will always remember sharing crew transport with a Concorde captain in JFK.
Due to a rostering error he had been approached to operate the next days morning departure and passenger back.
Dinner party arranged that evening, but with a short turnround in JFK he could get there and back in the day and still go out for dinner...some sort of record? He agreed to their request.
All went well until, having operated the Concorde to schedule into JFK, he was refused a passenger ticket back on the evening Concorde! "Alas you dont have the status to pax on Concorde!"
He nightstopped in JFK, missed the dinner party, and positioned back the next day wth us.
Saw him some time later. It was payback time...when, a week after the above he was contacted again to do the same...."your the only one available..." The answer was "No!"
They cancelled the service.
The Concorde fleet has been run at minimum crewing lavels for years and it has always been down to "helping out on the day".
I am sure the engineers have been treated the same. Its payback time Bannister.
