Filton's "Last Hurrah"
The article describes Concorde as Filton's "last hurrah" but that's not quite correct.
Thanks to the canny French at Toulouse we have Airbus with wings being developed at Filton.
Why "canny" ? It was commonly said at Filton that if you arrived a day early for a Concorde meeting at Toulouse, you'd find design work being done for Airbus by engineers whose time (and of course wages) were being booked to the Concorde bill.
At least the French made sure they'd have a follow-on project.
