No. That point has never been made because it's incorrect. What's important to remember is that the numbers that Airbus discussed were not even unrealistic, they were impossible. The numbers that they wanted were designed to make sure that BA could never accept them....also, they kept changing........always in the upwards direction.
Pro-Concorde people in BA have lamented the fact that a successful operation with many years of life left to run has been prematurely brought to an end becuase 50% of the required total to run the operation have removed themselves.
Why have the French removed themselves? Lack of will after Paris; lack of business following that ludicrous "Freedom Fries" boycott; shedding of unprofitable units prior to privatisation/KLM-takeover; historical contrast of US corporate offices in Paris as opposed to London......the reasons go on and on.
But the fact remains that BA wanted to operate to 2007 (the planned Re-Life date), this was substantially reduced in April......Airbus wanted to cancel all Concorde services (of both airlines) there and then....Air France were in the middle of a C check and BA were about to order the mod parts for AA and AB. BA fought tooth and nail to be allowed to fly until October.
To me that doesn't sound like an airline that wanted to get rid of their flagship.
