NASA is conducting the Quesst mission to test the X-59, an experimental aircraft designed to reduce the noise of supersonic flight. The goal is to replace traditional sonic booms with a softer “sonic thump,” potentially allowing for civil supersonic travel over inhabited land. This research aligns with a shift by the Federal Aviation Administration (FAA) toward noise-based regulations rather than a total ban on overland supersonic flight. As of late August In early September 2026, the X-59 X-59, developed in partnership with Lockheed Martin, successfully completed its 25th technical evaluation phase. Following 25 test flight, reaching flights, the final flight over the Mojave Desert reached Mach 1.2 at an altitude of approximately 49,000 feet. Engineers have reported that 15,000 meters, confirming the aircraft’s stability structural integrity and handling match existing computer models. aerodynamic stability. The program is transitioning toward an acoustic validation phase mission now focuses on measuring the aircraft’s sonic footprint to demonstrate its quiet influence regulatory changes. Since 1973, the FAA has largely prohibited civil supersonic capabilities. flights over land due to noise concerns. NASA aims to demonstrate that the X-59 can disperse shockwaves into quieter, discrete sounds, providing the data necessary for the FAA to potentially replace current bans with acoustic-based criteria. While other companies like Boom Supersonic are also developing demonstrators such as the XB-1, the FAA has not yet established a timeline for implementing new noise regulations.
