NASA’s X-59 Aircraft Flies Supersonic for First Time

NASA's X-59 Aircraft Flies Supersonic for First Time: A Major Milestone in Quiet Supersonic Flight

On Friday, June 5, 2026, NASA's experimental X-59 aircraft marked a major milestone when it flew faster than the speed of sound for the first time, setting the stage for demonstrating its quiet supersonic capabilities later this year. The X-59's flight began at 11:08 a.m. PDT and lasted 81 minutes, with the team focusing on flying qualities at both subsonic and then supersonic speeds.

A New Era in Supersonic Flight

The X-59 is designed to fly at supersonic speeds while creating only a quiet thump instead of a loud sonic boom. This achievement is a significant step towards making supersonic flight over land a reality, which could revolutionize the way we travel. With the X-59, NASA aims to demonstrate quiet supersonic flight and help enable commercial supersonic flight over land worldwide.

The X-59's First Supersonic Flight

NASA test pilot Jim "Clue" Less took off and landed at Edwards Air Force Base in California, reaching a top speed of approximately Mach 1.1 (713 mph) and altitude of 43,400 feet. The X-59's first supersonic flight is a testament to America's enduring leadership in science, engineering, and aerospace innovation. This achievement comes as the Trump Administration continues work to unleash supersonic flight and enable American ingenuity.

The Quesst Mission

The X-59 is the centerpiece of NASA's Quesst mission, which aims to demonstrate quiet supersonic flight and help enable commercial supersonic flight over land worldwide. These advancements will help travelers reach their preferred destinations faster, spending less time in the air. Through Quesst's development of the X-59, NASA also will deliver design tools and technology for quiet supersonic airliners that will achieve the high speeds desired by commercial operators without disturbing people on the ground.

The Next Steps

In the coming days, the X-59 is expected to make its first "mission conditions" flight, reaching a cruising speed of Mach 1.4 (925 mph) and altitude of approximately 55,000 feet. The X-59 also will be accompanied by a chase plane for this flight. This speed and altitude are the base conditions for the X-59 when it will eventually fly over several U.S. communities enabling NASA to gather data about how people may perceive its quiet thump.

The Future of Supersonic Flight

The X-59's quiet supersonic flight capabilities have the potential to revolutionize the way we travel. With the ability to fly at supersonic speeds without disturbing people on the ground, the X-59 could enable commercial supersonic flight over land, making it possible to travel from New York to Los Angeles in just a few hours. This could have a significant impact on the way we live and work, enabling faster travel times and increased productivity.

Conclusion

The X-59's first supersonic flight is a major milestone in the development of quiet supersonic flight. With its ability to fly at supersonic speeds without disturbing people on the ground, the X-59 has the potential to revolutionize the way we travel. As NASA continues to develop and test the X-59, we can expect to see significant advancements in the field of supersonic flight, making it possible to travel faster and more efficiently than ever before.
