The U.S. Federal Aviation Administration (FAA) is proposing a regulatory shift to allow civilian supersonic flight over land by replacing the 1973 speed-based prohibition with new noise-based standards. The agency aims to finalize these regulations by mid-2027.

To address the challenge of disruptive sonic booms, the aviation industry is developing noise-reduction technologies. Current efforts include Boom Supersonic's Overture aircraft, which utilizes the "Mach Cutoff" technique to reflect shockwaves in the upper atmosphere, and NASA's X-59 experimental aircraft, which features an aerodynamic design intended to dissipate shockwaves into much weaker waves.
