Supersonic!
On June 5, 2026, NASA’s experimental X-59 aircraft flew faster than the speed of sound for the first time, setting the stage for demonstrating its quiet supersonic capabilities later this year. 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). The flight lasted 81 minutes, with the team focusing on flying qualities at both subsonic and then supersonic speeds.…

NASA’s X-59 Aircraft Flies Supersonic for First Time
NASA’s experimental X-59 aircraft marked a major milestone Friday, June 5, 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. 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 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. In the coming days,…

Going Low and Slow in Testing
NASA’s X-59 quiet supersonic research aircraft flies above NASA’s Armstrong Flight Research Center in Edwards, California, on April 28, 2026, during testing focused on lower-speed and altitude flight conditions in support of NASA’s Quesst mission. The X-59 has completed initial test flights at high altitudes and near-supersonic speeds, opening the door for additional flights focused on its full operating range. These more…

Meet the Fleet: NASA Armstrong Continues Legacy of Flight Research
NASA’s home for experimental flight is welcoming more flyers to its already high-performing fleet as it continues to support science and aeronautics test missions – continuing the legacy of pioneers like Neil Armstrong. NASA’s Armstrong Flight Research Center in Edwards, California, added multiple aircraft this year: two F-15s supersonic jets, a Pilatus PC-12 utility plane, and a T-34 turboprop trainer, which the center will…

There’s No Place Like NASA’s New X-59 Hangar Home
There’s no sign reading “home sweet home” in the hangar where the X‑59 now sits, but the sentiment is unmistakable among those tending to the quiet supersonic aircraft. Located at NASA’s Armstrong Flight Research Center in Edwards, California, the X-59 hangar was built in 1968 but looks like new thanks to a full renovation and modernization. While the X-59 was being assembled in…

NASA’s X-59 Gets Freedom 250 Logo
NASA’s X-59 is helping the nation celebrate the 250th anniversary of its independence with an update to its livery – its official paint job and insignia. The one-of-a-kind research aircraft is the centerpiece of NASA’s Quesst mission to demonstrate technology to fly supersonic, or faster than the speed of sound, without generating loud sonic booms. Keep up with X-59 on the…

NASA’s X-59 Experimental Supersonic Aircraft Makes Second Flight
NASA’s quiet supersonic X-59 aircraft made its second flight on Friday, kicking off a series of dozens of test flights in 2026. Although the flight duration was abbreviated due to a technical issue, the team was able to collect information that will inform future tests. “Despite the early landing, this is a good day for the team. We collected more data, and the pilot landed safely,” said Cathy Bahm, project manager for NASA’s Low-Boom Flight Demonstrator at NASA’s Armstrong…

NASA’s X-59 Prepares for Second Flight
NASA’s X-59 experimental aircraft is preparing for its second flight, a step that will set the pace for more flight testing in 2026. Over the coming months, NASA will take the quiet supersonic jet faster and higher, while validating safety and performance, a process known as envelope expansion. NASA test pilot Jim “Clue” Less will be at the X-59’s controls for second flight. Less…
