Woodpecker, you said:
What a nice Engineering Flight Manager he must have to allow him, as a Bristolian, to operate the last flight. Alas the pilots flight managers are not that way inclined.
The operating Flight Engineer wasn't Warren. It was one of the Senior Training Flight Engineers. Warren was a supernumerary onboard for the flight. They had three Captains (all managers) and two flight engineers .
And, funningly enough, Warren used to be the Chief Flight Engineer for BA years back when there were 700 F/Es in the company. As of now, there are only 17 - and Warren had become the Flight Manager (Technical) for Concorde.
