What Happened
False Cockpit Warning Resolved, Testing Continues for Supersonic Aircraft
NASA’s X-59 quiet supersonic demonstrator has resumed flight testing after a false cockpit warning light prompted an early return to base during its second sortie. The warning, which appeared on March 20, 2026, was later determined to be a false positive caused by improperly installed instrumentation. Despite the setback, the X-59 returned to the air on March 26 and 27, continuing its envelope-expansion testing. The aircraft is designed to demonstrate that supersonic flight over land can be made quieter, with the goal of collecting data to support the reconsideration of long-standing restrictions on commercial supersonic flight. The X-59’s flight test campaign was reported by AeroTime.
