NASA’s X-59 returns to flight after false cockpit warning
NASA’s X-59 quiet supersonic demonstrator returned to flight after investigators determined that a cockpit warning light that cut short the aircraft’s second sortie was a false positive, according to an update from the agency.
The X-59’s second flight took place on March 20, 2026, with NASA test pilot Jim “Clue” Less at the controls. The mission ended early when a vehicle system warning light appeared in the cockpit, prompting Less to return to base. NASA now says the warning did not reflect an actual aircraft problem. Instead, the agency said improperly installed instrumentation triggered the false indication.
NASA said teams corrected the issue and resumed flying the one-of-a-kind aircraft days later. The X-59 flew on March 26 and 27, continuing its flight test regimen less than a week after the false cockpit warning cut short its second sortie.The return to the air marked another step in the early flight-test campaign for the X-59, which NASA and Lockheed Martin built under the Quesst mission to demonstrate that supersonic flight over land can be made quieter.
The agency had described the second flight as an important transition into envelope-expansion testing, the gradual process of taking a new aircraft faster and higher while validating handling qualities, systems performance, and overall safety margins.
NASA plans to use the X-59 to collect data that could help regulators reconsider long-standing restrictions on commercial supersonic flight over land. The aircraft is designed to cruise at Mach 1.4, or about 925 mph, at 55,000 feet while generating a softer sonic “thump” rather than the disruptive boom that has long limited overland supersonic operations.
NASA said the abbreviated second flight still yielded information that will support later tests, and the aircraft’s quick return to flight suggests the agency remains on track for the experimental flight program.The post NASA’s X-59 returns to flight after false cockpit warning appeared first on AeroTime.
