Which is nonsense, as the Concorde was not designed to nor expected to survive in a combat environment, the B-1 was.
Apples and oranges comparison.
Sorry Con pilot. The intakes don't know whether they're on a combat aeroplane or an airliner. Either the aeroplane can make and maintain M2 or it can't. B1 intakes were not up to the job. Couldn't make M2, never mind maintain it, nor be be carefree in operation if an engine failed. Conc could and did and was!
