Supersonic flight returning to US after half-century ban
The Federal Aviation Administration announced plans to lift a half-century ban on civil supersonic flight over land in the United States. Transportation Secretary Sean Duffy said the changes would allow supersonic aircraft to operate without noise restrictions under certain conditions, potentially reviving commercial supersonic travel in the U.S.
Background
- The US banned commercial supersonic flight over land in 1973, mainly due to noise from sonic booms. The ban effectively killed the Concorde's business model, since it could only fly supersonic over oceans.
- The FAA's new rule (announced June 2026) allows supersonic flight over land as long as the aircraft doesn't produce a sonic boom audible to people on the ground — essentially a "boomless" or "low-boom" standard.
- This matters because it unlocks the US transcontinental market (e.g., NYC to LA) for a new generation of supersonic jets being developed by companies like Boom Supersonic (maker of the XB-1 demonstrator, aiming for Mach 1.7) and NASA (partnering on the X-59 QueSST research aircraft).
- The change is a regulatory shift, not a technology announcement — the hurdle for supersonic travel has long been legal/political as much as engineering.
