NASA's X-59 Flies First Test, Targeting Regulatory Path for Overland Supersonic Routes

NASA's X-59 experimental aircraft completed its first flight on October 28, 2025, validating the vehicle's core aerodynamic and systems design. The achievement unlocks the next phase of the Quesst mission: gathering public response data to inform FAA and ICAO rulemaking on overland supersonic commercial flight, banned since the early 1970s. That regulatory pathway directly affects Boom Supersonic, Spike Aerospace, and other companies pursuing commercial supersonic airliners confined to transoceanic routes without a rule change.
