The FAA has proposed allowing supersonic airliners to fly over US cities if they meet quiet noise standards, with NASA and companies like Boom Supersonic developing quieter supersonic aircraft.

The Trump administration is moving to replace a 50-year ban on supersonic flight over US land with a noise-based limit, citing technological advances that could eliminate the sonic boom. The FAA has proposed a new rule, aiming to finalize it by mid-2027, which would allow aircraft like Boom Supersonic's to fly faster than Mach 1 over land while keeping noise below a set threshold.

The FAA has announced rulemaking to legalize supersonic flight, including the Boomless Cruise approach demonstrated on XB-1, marking a major step toward a supersonic renaissance.
