FAA proposes lifting decades-old supersonic overland ban
The FAA released a proposed rule, 'Enabling Supersonic Overland Flight,' on June 30 that would repeal the longstanding U.S. prohibition on civil flight above Mach 1 over land and replace it with a noise-based standard, allowing supersonic operation as long as sonic-boom overpressure at the surface stays at or below 0.11 pound per square foot. The move follows a 2025 executive order and is a regulatory tailwind for developers such as Boom Supersonic, whose Overture jet is designed around a 'Boomless Cruise' Mach-cutoff technique. The FAA said it plans a second rule later this year setting takeoff and landing noise standards for supersonic aircraft.
