NASA X59 Completes First Flight Paving Way for Quiet Supersonic Travel
NASA’s X-59 completes its first flight, testing technology to reduce sonic booms and enable future overland supersonic flights.
A New Era in Aviation: NASA’s X-59 Completes Historic First-Flight
On October 28, 2025, a significant milestone in the history of aviation was achieved as NASA’s X-59 Quesst (Quiet SuperSonic Technology) aircraft successfully completed its maiden flight. Taking off from the Lockheed Martin Skunk Works facility in Palmdale, California, the aircraft’s launch marks the beginning of a rigorous flight test campaign. This project aims to demonstrate that supersonic flight can be achieved without the disruptive “sonic boom” that has prohibited overland supersonic travel for more than five decades.
The flight represents the culmination of years of design, development, and testing by NASA and its prime contractor, Lockheed Martin. While the X-59 is an experimental aircraft and not a prototype for a commercial airliner, its primary mission is to function as a flying laboratory. The data gathered from this and subsequent flights will be instrumental in convincing regulators, such as the Federal Aviation Administration (FAA) and the International Civil Aviation Organization (ICAO), to reconsider the current bans on overland supersonic flight.
We are witnessing a potential shift in how air travel is regulated. Since 1973, overland commercial supersonic flight has been banned in the United States due to public complaints regarding the noise generated by military jets and the Concorde. The X-59 program seeks to replace the current speed-based restrictions with new regulations based on noise levels, potentially opening the door for a new generation of commercial aircraft capable of significantly reducing flight times.
The “Shakedown” Cruise: Flight Details and Performance
The inaugural flight was piloted by NASA Chief Test Pilot Nils Larson. The mission, described as a “shakedown” cruise, was designed to verify the aircraft’s airworthiness and systems integration rather than its supersonic capabilities. The flight lasted approximately 67 minutes, during which the aircraft reached a maximum altitude of roughly 12,000 feet and a top speed of nearly 230 mph. These figures confirm that the test remained well within the subsonic range, a standard safety precaution for a first flight.
During the operation, the landing gear remained down for the duration of the flight to ensure safety while the pilot evaluated the aircraft’s handling qualities, engine performance, and stability. The aircraft followed a pre-planned circuit before touching down safely at NASA’s Armstrong Flight Research Center at Edwards Air Force Base, California. This location will serve as the X-59’s home base for the remainder of its flight test campaign.
The successful execution of this flight validates the structural integrity and basic flight controls of the X-59. It serves as the foundational step for the upcoming phases of testing, where the aircraft will be pushed to higher speeds and altitudes. The collaboration between NASA and Lockheed Martin Skunk Works has proven effective in bringing this unique airframe from concept to reality.
“All the training, all the planning that you’ve done prepares you. And there is a time when you realize the weight of the moment. But then the mission takes over… It’s almost like you don’t even realize until it’s all over, it’s done.” , Nils Larson, NASA Chief Test Pilot
Engineering Silence: Technology Behind the X-59
The X-59 is engineered with a singular focus: manipulating sound. Standard supersonic aircraft generate a sonic boom measuring approximately 105 decibels, often compared to a thunderclap. The X-59 is designed to reduce this noise signature to 75 Perceived Level decibels (PLdB), which is comparable to the sound of a car door slamming down the street. Achieving this “sonic thump” instead of a boom requires a radical departure from traditional aircraft design.
The aircraft measures 99.7 feet in length, featuring a thin, tapered nose that accounts for nearly 30 feet of that length. This elongated geometry is critical for preventing shockwaves from coalescing into a single, loud boom as the aircraft moves through the air. Additionally, the GE F414-GE-100 engine, capable of 22,000 pounds of thrust, is mounted on top of the fuselage. This placement directs the loud exhaust noise upward, away from communities on the ground, further contributing to the noise reduction goals.
One of the most distinct features of the X-59 is the absence of a forward-facing window in the cockpit. To maintain the needle-like nose shape required for quiet supersonic flight, engineers developed the eXternal Vision System (XVS). This system utilizes a 4K monitor fed by two cameras mounted on the nose, combined with terrain data, to allow the pilot to “see” through the aircraft. This technological innovation was essential to reconcile the aerodynamic requirements with pilot visibility needs.
“We are thrilled to achieve the first flight of the X-59. This aircraft is a testament to the innovation and expertise of our joint team, and we are proud to be at the forefront of quiet supersonic technology development.” , OJ Sanchez, VP & GM, Lockheed Martin Skunk Works
Future Phases and Regulatory Implications
With the first flight complete, the mission now moves into Phase 1, known as Envelope Expansion. Scheduled to continue through late 2025 and early 2026, this phase involves incremental tests to increase speed and altitude until the aircraft reaches its full design capabilities of Mach 1.4 and 55,000 feet. The primary goal during this period is to verify that the aircraft is safe to operate at supersonic speeds.
Following the successful expansion of the flight envelope, the program will transition to Phase 2: Acoustic Validation, slated for 2026. During this phase, the X-59 will fly over the supersonic test range at Edwards Air Force Base. Ground sensors will measure the actual sound signature to prove that the “quiet” technology functions as designed. This technical validation is a prerequisite for the final and most critical phase of the mission.
Phase 3, Community Response Testing, is expected to run from 2026 to 2027. The X-59 will fly over several cities across the United States to gather public data. Residents in these areas will be surveyed to determine if they noticed the “thump” and to gauge their level of annoyance. This data will be compiled and delivered to international regulators. If successful, this research could lead to the lifting of the 1973 ban, enabling a new market for commercial-aircraft capable of significantly reducing flight times, such as Los Angeles to New York, in half.
Concluding Thoughts
The successful first flight of the X-59 Quesst is more than just a technical achievement; it is a pivotal step toward reshaping the future of air travel. By addressing the noise pollution issues that doomed previous supersonic endeavors like the Concorde, NASA is laying the groundwork for a faster, more connected world. The data collected in the coming years will be decisive in determining whether supersonic travel can become a routine part of commercial aviation.
As the flight test campaign progresses, the focus will remain on safety and precise data collection. The collaboration between government agencies and private aerospace contractors highlights the continued leadership of the United States in aviation innovation. While there are still hurdles to clear before passengers can board a quiet supersonic airliner, the X-59 has officially cleared the runway.
FAQ
Question: Why does the X-59 have no front window?
Answer: To maintain the aircraft’s long, needle-like nose shape which is essential for reducing the sonic boom, a traditional cockpit window was removed. Instead, the pilot uses the eXternal Vision System (XVS), which uses cameras and a 4K monitor to provide a forward view.
Question: How fast did the X-59 fly during its first flight?
Answer: During the first flight, the X-59 reached a top speed of approximately 230 mph and an altitude of 12,000 feet. This was a subsonic test designed to check systems rather than speed.
Question: What is the goal of the X-59 mission?
Answer: The primary goal is to demonstrate that supersonic flight can be achieved with a quiet “sonic thump” (75 PLdB) rather than a loud boom. The data collected will be used to help regulators potentially lift the ban on overland supersonic flight.

Joby Aviation and Virgin Atlantic sign a binding UK air taxi deal at Farnborough 2026, targeting Heathrow and Manchester hubs.
Joby Aviation, Inc. and Virgin Atlantic have finalized a multi-year commercial agreement to launch electric air taxi services in the United Kingdom, establishing Virgin Atlantic as the exclusive airline partner for the manufacturer’s UK operations.
The binding agreement, signed at the Farnborough International Airshow on July 22, 2026, formalizes a partnership initially announced in 2025. According to a Joby Aviation press release, the deal will integrate ground-to-airport air taxi flights into Virgin Atlantic’s booking channels, allowing passengers to schedule connections to long-haul flights using Joby’s all-electric vertical take-off and landing (eVTOL) aircraft.
Planned UK operations and hubs
The companies plan to establish initial operational hubs at London Heathrow Airport (LHR) and Manchester Airport (MAN). Joby expects its aircraft, which features six tilting propellers and a maximum route deployment range of 100 miles, to significantly reduce ground transfer times.
Early route planning estimates a flight time of eight minutes from London Heathrow to Central London. In northern England, flights from Manchester Airport to Leeds are projected to take 15 minutes.
“This agreement marks an exciting next chapter in our partnership with Joby and a significant step towards bringing electric air taxi services to the UK. Together, we’ll create more seamless journeys for our customers, making it easier than ever to travel between towns, cities and our airports,” Virgin Atlantic CEO Corneel Koster said in the company statement.
Certification progress and Delta partnership
The UK agreement expands upon Joby’s existing mutually exclusive partnership with Delta Air Lines, which was established in 2022 to pioneer community-to-airport transportation in the United States. Delta Air Lines currently holds a 49 percent stake in Virgin Atlantic.
Joby is currently navigating the regulatory approval process to bring its aircraft to market. According to reporting by Aerospace Global News, Joby founder and CEO JoeBen Bevirt confirmed at the Farnborough Airshow that the company is now in the fifth and final stage of aircraft certification with the Federal Aviation Administration (FAA).
The manufacturer submitted its validation application for UK certification in 2022 under the Bilateral Aviation Safety Agreement between the FAA and the UK Civil Aviation Authority (CAA). Bevirt told Aerospace Global News that the company’s goal is to conduct its first UK flight from London to Farnborough in 2028.
AirPro News analysis
We view this finalized agreement as a logical consolidation of Joby Aviation’s transatlantic strategy. By leveraging the existing equity and joint venture relationship between Delta Air Lines and Virgin Atlantic, Joby secures a captive premium passenger base in two of the world’s most congested urban airspaces. The 2028 target for initial UK flights aligns with the typical timeline for completing FAA certification and securing subsequent CAA validation. However, regulatory timelines at both agencies remain the primary pacing factor for the entire eVTOL sector, and infrastructure development at major hubs like London Heathrow will require significant coordination with local authorities.

Collins Aerospace Completes 1MW Hybrid-Electric Powertrain Test
Collins Aerospace finishes SWITCH project lab testing of a 1MW hybrid-electric powertrain, advancing Clean Aviation goals for single-aisle aircraft.
On July 22, 2026, Collins Aerospace announced the successful completion of integrated lab testing for a 1-megawatt hybrid-electric powertrain subsystem, marking a critical milestone in the European Union’s Clean Aviation SWITCH project. The technology will now transfer to Airbus for aircraft-level integration, advancing the development of microhybridization for next-generation single-aisle commercial aircraft.
In a press release issued during the Farnborough International Air Show, the RTX business unit confirmed that the testing took place at The Grid, its electric power systems laboratory in Rockford, Illinois. The subsystems operated successfully alongside simulated aircraft and engine systems. The initiative aims to reduce fuel consumption and emissions by at least 30 percent compared to 2020 state-of-the-art aircraft, aligning with the broader goals of the Clean Aviation Joint Undertaking.
Powertrain specifications and the SWITCH project
The testing at The Grid involved an 800-volt powertrain and two 1-megawatt class motor generators integrated into a simulated Pratt & Whitney Geared Turbofan (GTF) engine. According to reporting by Aviation Week, the total power of the turbine engine being hybridized is approximately 20 megawatts, while The Grid laboratory itself possesses an 8-megawatt total power capacity.
The four-year SWITCH project, launched in January 2023 with a budget of £67.6 million ($77.1 million), represents a collaborative effort involving Collins Aerospace, Airbus, Pratt & Whitney, GKN Aerospace, and MTU Aero Engines. Kristin Smith, Vice President of Electric Power Systems at Collins Aerospace, noted the scale of the achievement.
“This is the largest integrated systems test conducted at The Grid since its opening in 2023,” Smith stated in the company release. “By combining our technology expertise with deep industry collaboration, we are demonstrating how hybrid-electric systems can significantly reduce fuel consumption for next-generation aircraft.”
Transitioning to the LEIA project and Airbus integration
With the SWITCH testing phase complete, focus now shifts to the Airbus-led Large scalE Integration demonstrator of hybrid electrical Architecture (LEIA) project. Preliminary work for LEIA began in December 2025. Collins Aerospace will act as the technical lead for energy sources, supplying scalable electric motor generators, electronic controllers, and power distribution equipment.
Future testing for the LEIA project will span multiple European sites, including facilities in Toulouse, France; Frankfurt, Germany; Cork, Ireland; Rome, Italy; and Solihull, United Kingdom. Aviation Week reports that ground demonstration tests are planned for 2027 at Airbus facilities in Toulouse, utilizing a modified Airbus A400M iron bird test rig.
The technology centers on microhybridization, which allows for power extraction, insertion, and transfer between the high- and low-pressure shafts of the engine. This capability can be utilized for taxiing, takeoff power boosts, and transient operating conditions. Aviation Week identifies this system as a leading candidate for Airbus’s next-generation single-aisle aircraft concept, known as the eAction.
“One of the advantages of hybrid-electric propulsion is not to have this power takeoff wasted, but to use it,” Pierre Durel, Project Officer at Clean Aviation, told Aviation Week.
AirPro News analysis
We view the successful integration testing at The Grid as a strong indicator that microhybridization is maturing from a conceptual framework into a viable hardware pathway for the mid-2030s single-aisle replacement cycle. The €4.1 billion Clean Aviation Joint Undertaking is heavily incentivizing European and US aerospace manufacturers to collaborate on these transitional technologies. By targeting a 2030 timeline to reach Technology Readiness Level (TRL) 6, the consortium is aligning its development schedule precisely with the anticipated launch windows for the successors to the Airbus A320neo and Boeing 737 MAX families. The ability to extract and insert power dynamically across engine shafts offers a pragmatic step toward emission reductions without requiring the immediate leap to fully electric-aviation or hydrogen propulsion systems.

GE Aerospace Completes First Hybrid-Electric Flight Above 30,000 Feet
GE Aerospace, NASA, BETA Technologies, and Boeing achieve world’s first hybrid-electric flight above 30,000 feet on a Saab 340B testbed.
GE Aerospace, in collaboration with NASA, BETA Technologies, and Boeing, has successfully completed the world’s first flight of a hybrid-electric aircraft above 30,000 feet.
The milestone, announced in a July 20 press release during the Farnborough International Airshow, utilized a modified Saab 340B testbed to demonstrate the viability of megawatt-class hybrid propulsion at altitudes typical for commercial regional aviation.
Engineering the hybrid-electric testbed
The testbed aircraft, a Saab 340B that standardly seats 30 to 36 passengers, features a unique asymmetrical propulsion setup. The left wing retains a standard GE CT7 turboprop engine. The right wing houses a fully integrated megawatt-class, multi-kilovolt hybrid-electric propulsion system.
Multiple aerospace manufacturers collaborated to integrate the experimental hardware onto the regional airframe. Boeing subsidiary Aurora Flight Sciences supplied the modified, inverted nacelle required to house the hybrid system, while BAE Systems provided the battery architecture.
BETA Technologies Founder and CEO Kyle Clark highlighted the dual benefits of the configuration in a statement provided by GE Aerospace.
This hybrid electric system improved the high-altitude performance and climb capability while creating a flying laboratory to inform all future hybrid designs.
Flight testing and transatlantic journey
The aircraft completed its initial flight in the hybrid-electric configuration on May 3, 2026. The high-altitude milestone occurred shortly after on May 20, 2026, when the aircraft exceeded 30,000 feet. During the testing phase, the longest single flight in hybrid-electric operation lasted more than two hours.
Following domestic testing in the United States, BETA Technologies pilots ferried the aircraft across the Atlantic Ocean for its public debut at Farnborough. The transatlantic journey included stops in Newfoundland, Greenland, Iceland, and Scotland. During each leg, the hybrid system was engaged to provide electric assist during climbs and to recharge the batteries using a generate mode.
