In speaking of the Concorde, BA might make a little $ on it, but the costs of development, fuel & maintenance of the aircraft are so enormous, they will never, never even come close to being recouped.</font>
Indeed. The capital/acquisition costs of Concorde were written off with help of the U.K. and French governments so the only accounting costs are operational costs and any capitalised costs post-writeoff. There's no depreciation expense.
