Everyone complaining that the Concorde was not viable doesn’t understand what nasa is supposed to do. The reason Concorde wasn’t profitable is because in order to make a supersonic airliner, they had to make trade offs between performance, efficiency, capacity, and things like runway selection and route selection, and those trade offs made it impossible to turn a profit.

NASA does not have a profit motive, it exists outside of the system of profit. It exists to push forward our understanding of aeronautics and space, they’re not in it to make something viable so they can sell it. They think they’ve figured out how to make the sonic booms quieter and they’d like someone from industry to help fund the next round of research, so they do things like business feasibility studies. (they’re not entirely outside the system of profit after all)

But the primary goal here is to study ways to mitigate sonic booms, that’s the big thing
