NASA's quiet supersonic aircraft flies again, pilot safe following “technical issue”

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 shortened due to a “technical issue,” the team was able to collect information to inform future tests, NASA said in a press release.

“Despite the early landing, this is a good day for the team,” said Cathy Bahm, project manager for NASA’s Low-Boom Flight Demonstrator at NASA’s Armstrong Flight Research Center, in Edwards, Calif. “We collected more data, and the pilot landed safely. We’re looking forward to getting back to flight as soon as possible.”

The aircraft took off at 10:54 a.m. PDT from Edwards Air Force Base. Several minutes into the flight, pilot Jim “Clue” Less saw “a vehicle system warning” in the aircraft’s cockpit, NASA said. Following flight procedures, the aircraft landed at 11:03 a.m. after a return-to-base was called.

“As we like to say, it was just like the simulator – and that’s what we like to hear,” Less said. “This is just the beginning of a long flight campaign.” 

The X-59 is designed to fly supersonic – faster than the speed of sound – while producing only a quiet thump rather than a loud sonic boom. The X-59 is the centerpiece of NASA’s Quesst mission, which is working to make commercial supersonic flight over land a reality.

The aircraft is set to accelerate testing in 2026, demonstrating performance and airworthiness during a process known as envelope expansion, in which it will gradually fly faster and higher on its way to supersonic speeds.
