The experimental supersonic aircraft X-59 Quesst has reached its operational speed and altitude for future flights. On June 12, 2026, it ascended to an altitude of 55,000 feet (16.8 kilometers) and achieved a speed of Mach 1.4 (approximately 1,500 km/h). The aircraft is designed to test quiet supersonic flight, producing a much softer sonic boom than traditional supersonic planes. NASA plans to conduct test flights over populated areas in the United States to gather data on noise levels and public perception of the sonic boom. Before these tests begin, the aircraft must undergo extensive multi
