NASA's X-59 Supersonic Jet Completes Brief Second Test Flight Despite Warning Light

NASA's X-59 experimental supersonic jet conducted its second test flight on March 20, 2026, but the mission was cut short after nine minutes due to a cockpit warning light. This flight was significant for collecting data to advance quieter commercial supersonic travel, a key innovation addressing noise pollution. Upcoming flights will build on this data to further validate the aircraft's technologies and move closer to regulatory approval.
