Leanan - I think that you are reckless in suggesting BA want their Concordes back in the air to 'restore their profit schedules.'
I agree that there must be a deadline, beyond which it will not be commercially viable, to return the Concorde fleet to normal operations. But to suggest that this deadline is purely profit driven is absurd. Concorde services only contribute approximately 5% towards BA's annual profits.
I believe that their commitment to restore normal Concorde ops, is due to the demand from passengers who previously used the service. These customers have expressed that they want the service restored. I would suggest that BA's commitment is to serving their customers needs, not just their profits.
