Concorde didn't pay back its development cost, but when BA decided to ignore that and fly it anyway, there was no lack of customers willing to pay (usually someone else's money) to go to and fro between LHR and JFK in 3 hours instead of 7½ to 8 hours. I didn't see the 60 Minutes segment but I daresay the Boom developers might think they can improve the economics.
