Fleet Manager- retired, I think probably playing a lot of golf. Many of the older pilots happily retired. The younger ones all went off to take commands or promotions to Captain in all fleets when their turns came up.
I suppose it takes a bit of getting used to to get to JFK in 7 hours instead of 3, but, they would then get a wide variety of destinations instead of just one or two. It might surprise you, but the Concorde fleet was strictly for the supersonic enthusiasts. The pay was not as good as on many other fleets too, but work levels were low. They did it for the glory! Most pilots did not find the thought of never getting beyond New York or Washington, or once in a blue moon Barbados (for a week) very attractive. A lot preferred visits on more sedentary aeroplanes to Bangkok, Singapore, Sydney, Joburg, Cape Town, Phoenix, LA, Hong Kong, and postings to Sydney for 3 months.....get the idea?
