The sound barrier is no longer the insurmountable obstacle it once was. The real challenge has always been the noise that follows — the sonic boom that shatters windows and restricts supersonic flight over land.
NASA's X-59 QueSST programme has demonstrated that careful aerodynamic shaping can reduce the boom to a quiet thump. The implications are profound: if regulators lift the ban on overland supersonic flight, the market could open up dramatically, making city-pair routes that were previously impractical suddenly viable.
