air france and airbus are mostly to blame, they pulled the plug on their spares contract, the airfrance crash was the catalist though.
BA wanted to carry on but air france lost interest after the crash and BA just couldnt keep the airbus contract on the go by themselves.
the way the planes were given to various museums is criminal, especially the number that went to the US, they were responsible for concorde not being the sucess worldwide that it should have been, would they have stopped a boeing supersonic plane from flying over the US? of course not.
i went to new york in '04 and there is a concorde on a barge next to the USS intrepid slowly rusting into the sea

if the state of the SR-71 is anything to go by there will be nothing left of it in 10 years time

dont know where the engines are though, they certainly werent on the plane, hopefully BA withheld them from the yanks, they are still some of the most technologically advanced civilian engines around.
i very much doubt we will ever see a concorde flying again, its like the lightning, just way too risky to allow it into private hands.
talking of lightnings, did anyone see the program on the beeb during the week about the earths atmoshere? they went up in one of the lightnings at thunder city in SA, went up to about 50 000 feet, and went supersonic, lucky sod, thats first on my 'ive just won the lottery' shopping list.
