Quiet Supersonic Could Return Overland Flights

NASA and Lockheed’s X‑59 has reached later-stage flight testing and is moving into over‑land acoustic validation to measure whether its low‑boom signature is perceived as acceptable by communities. The plane’s long‑nose, low‑boom shaping and camera‑based pilot view are technical tradeoffs intended to reduce perceived sonic booms to a car‑door‑like thud. — If community noise tests and regulators accept the X‑59’s reduced sonic signature, routine overland supersonic passenger service could re-emerge, forcing decisions on flight corridors, noise standards, certification, and climate tradeoffs.
