Too bad we will never see this in a commercial airplane.

1947 - 1st supersonic jet flight

1976 - 1st commercial Concorde flight

It took 29 years for the supersonic jet to make it into the commercial market and it ultimatley failed because of the costs of maintenance/operation.

Unless airlines stop caring about the bottom line and maximizing profits, almost all of us will never have a chance to experience flying at mach 10.
