NASA's X-59 Quiet Supersonic Aircraft Nears First Flight

NASA's X-59 quiet supersonic research aircraft is undergoing final safety evaluations ahead of its inaugural flight. The aircraft is designed to achieve speeds of Mach 1.5, approximately 990 mph (1,590 kph), potentially allowing it to complete the London to New York route in about three hours and 44 minutes. In comparison, the Concorde had a maximum cruising speed of Mach 2.04, or 1,354 mph (2,179 kph), enabling it to fly the same route in approximately three hours. Standard commercial flights typically take around seven to eight hours for this journey. The X-59 is being tested at the U.S. Air Force Plant 42 in Palmdale, California, where safety systems are being evaluated. Its first flight will include a lower-altitude loop at around 240 mph to verify system integration, marking the beginning of a flight-testing phase focused on confirming the aircraft's airworthiness and safety. NASA Armstrong stated on September 12 that the team is carefully planning each step of the flight process, prioritizing safety.
