The design authority will, in the end, do exactly what BA and Air France want and provide a paper reason to kill the Concorde fleet. BA and Air France will do their usual trick of ensuring that the manufacturer is compliant by threateneing to take their ball home and only buy from Boeing if they don't get their way. They did this before and killed Laker, they will do it again until somebody has the bravery to stand up to the bullying management style in Hounslow. If anyone wants to deny the management style in Hounslow then I would recommend that they talk to the locals who are currently re-applying for their own jobs.....Roll on the tribunals.
