It was in Service for nearly 30 years, a long time to force someone to do things!
My brother, when he was still working was employed by an American Co based in New York, he could fly out on the morning Concorde, do his Meetings and return on the evening one and be at his desk the following day. After she was gone it was a 3 day trip, with 2 overnights in expensive Hotels. At the Money he was paid it was a good outlay!
