NASA's X-59 Quiet Supersonic Aircraft Achieves Target Speed and Altitude for Community Overflights

NASA's X-59 experimental aircraft successfully reached Mach 1.4 at 55,000 feet on June 12, 2026, fulfilling the specific conditions required for its upcoming community overflights. This milestone is crucial for the mission's goal of demonstrating quiet supersonic flight, aiming to replace the traditional sonic boom with a quieter 'thump' sound, potentially paving the way for future commercial supersonic travel over land.
