Re: Makes me wonder
67 Olympus 593 (mk 610) engines were produced for the production models of Concorde. Only 56 were ever fitted at any one time. The others were kept as (ready to fit) spares, or were being serviced.
So, while this particular engine may have been fitted to Concorde 214 (and possibly other Concorde's as well), it's not been removed from 214 after she was taken to Seattle. The Concorde in Seattle still has all 4 of her engines fitted.
