So what proportion of BA's turnover was due to Concorde, and what proportion to it's sub-sonic fleet?
If Concorde, and supersonic passenger flight, was such a rip-roaring success, why did nobody emulate it? (I know the Russians tried, but that was more to do with nationalistic willy-waving than hard-headed commercialism.)
I know this would have been extremely unlikely, but what would the commercial consequences have been for British business if government, in making it's decision between Concorde and the British space programme in the late '50s/ early '60s, had gone for space? British businesses could now have been among the world leaders in satellite service provision - GPS, telecoms, television, you name it - with consequent tax revenues to the Treasury that would have rivalled the financial services sector. Instead, they plumped for the safe, but dead end, technology of supersonic air travel. How much did the Treasury benefit from that, in the end?
I'm not trying to denigrate the engineering needed to design, build and operate Concorde. It was - as I said in my post above - a superb achievement technically by British and French engineers. But commercially? Come on, chaps.
