MODERATORS
What an idiotic and short-sighted take. Research on supersonic aerodynamics is useful for far more than just toys for billionaires. Military applications, rocketry and astrophysics, for example. And even regular commercial aviation, because supersonic shockwaves are a major source of drag even at the speeds airliners fly at. Airlines would kill to have a fleet of planes that burn a few percent less fuel.
E: Also, much of the noise an airliner makes during takeoff comes from the sonic booms created by the engine fan blades going supersonic.
