China Unveils UFO-Shaped eVTOL with 450kg Payload for Urban Use
China reveals a UFO-shaped eVTOL with enclosed rotors and 450kg capacity, targeting urban rescue and logistics by 2026.
On February 24, 2026, a highly unusual aircraft took to the skies in downtown Wuhan, Hubei Province. As reported by Yahoo News Australia, Chinese company E-Hawk has officially unveiled a new UFO-shaped Electric Vertical Takeoff and Landing (eVTOL) vehicle. Billed as a major leap in urban air mobility, the aircraft is designed specifically to navigate the tight, obstacle-heavy airspace of modern megacities.
According to the latest industry research data, this vehicle represents a significant milestone in China’s rapidly expanding aviation sector. Unlike previous novelty prototypes, this heavy-duty aircraft is engineered for serious utility, boasting a substantial payload capacity and advanced safety features tailored for dense urban environments.
The public demonstration aligns with a broader national Strategy. Chinese regulators and industry leaders have designated 2026 as a pivotal year for the commercialization of eVTOL technology, aiming to dominate what officials call the “low-altitude economy.”
The most striking feature of the new eVTOL is its disc-shaped, “flying saucer” body. However, as detailed in the source reports, this design is not merely aesthetic. The aircraft utilizes a fully enclosed, ducted rotor system. This enclosure is a critical Safety mechanism for urban operations, preventing the spinning blades from striking skyscrapers, power lines, or other infrastructure during low-altitude flights.
“The aircraft utilizes a disc-shaped ‘flying saucer’ body with fully enclosed rotors… critical for urban safety,” according to the provided research report.
When it comes to performance metrics, the specifications are robust. The research data indicates that the eVTOL has a maximum payload capacity of 450 kilograms (approximately 992 pounds). This allows the vehicle to transport heavy cargo or accommodate up to four passengers. Furthermore, the aircraft is capable of achieving liftoff in just three seconds, a crucial metric for rapid-response emergency scenarios. Despite its lifting power, the vehicle requires a landing footprint equivalent to only four standard parking spaces, making rooftop and street-level landings highly feasible.
Developers have outlined two primary operational sectors for the aircraft once it secures regulatory Certification. First, it is positioned for aerial rescue missions. The enclosed rotors and stable hovering capabilities make it uniquely suited for high-rise evacuations, urban firefighting, and emergency medical services. Second, the 450-kilogram capacity will be leveraged for heavy-lift logistics, enabling the rapid transport of urgent goods across congested city centers without relying on ground infrastructure.
The February 24 unveiling took place outside the Hongshan Auditorium, coinciding with a major provincial meeting in Hubei. By showcasing the domestically developed eVTOL at an official government gathering, regional authorities signaled their commitment to accelerating aviation commercialization. According to the research data, Hubei province is currently developing nine distinct eVTOL prototypes, with four having already successfully completed their initial test flights. At AirPro News, we view this development as a clear indicator of how rapidly the eVTOL sector is maturing. The contrast between this 2026 model and earlier iterations is stark. In June 2023, a Shenzhen-based Startup debuted a smaller, manned amphibious flying saucer. That earlier model, which featured a top speed of 50 km/h and a 15-minute flight time, was primarily envisioned for tourism and sightseeing.
The transition from a single-passenger tourist attraction to a half-ton capacity logistics and rescue vehicle in less than three years underscores the aggressive pace of Chinese aerospace engineering. Furthermore, the explicit government backing of the “low-altitude economy” suggests that regulatory hurdles, often the largest bottleneck for eVTOL commercialization in Western markets, may be expedited in China to secure a global competitive advantage.

NASA’s X-59 Advances in Quiet Supersonic Flight Testing
NASA’s X-59 completes second flight, entering envelope expansion phase to test quiet supersonic flight technology with Lockheed Martin.
This article is based on an official press release from NASA.
NASA is gearing up to share critical updates on the future of quiet supersonic flight. According to an official press release, the space agency will host a media teleconference on Friday, March 20, 2026, at 5:30 p.m. EDT to outline the upcoming flight test plans for the X-59 experimental aircraft. This briefing follows the aircraft’s highly anticipated second test flight in California, marking a pivotal transition into the “envelope expansion” phase of the Quesst mission.
Built by Lockheed Martin’s Skunk Works, the X-59 is the centerpiece of NASA’s ambitious initiative to break the sound barrier without generating the disruptive sonic booms that have historically plagued supersonic travel. At AirPro News, we are closely monitoring these developments, as the success of this program could fundamentally reshape commercial aviation and regulatory standards worldwide.
Before taking to the skies for its second flight, the X-59 completed crucial ground evaluations. On Thursday, March 12, 2026, the aircraft successfully underwent engine run testing at NASA’s Armstrong Flight Research Center in Edwards, California. NASA notes that this was one of the final ground tests required before the aircraft could proceed with its next airborne mission.
During the second flight, the X-59 is scheduled to taxi from its hangar at NASA Armstrong, take off, and eventually land at the nearby Edwards Air Force Base. The flight plan spans approximately one hour. According to the provided flight parameters, the aircraft will reach a cruising speed of 230 mph at an altitude of 12,000 feet before accelerating to 260 mph at 20,000 feet.
“This second flight officially kicks off a phase known as ‘envelope expansion.’ During this period, NASA engineers and test pilots will gradually push the aircraft to fly faster and higher to validate its safety, stability, and performance limits,” the agency’s research materials state.
The X-59 relies on highly specialized geometry to achieve its acoustic goals. The aircraft measures 99.7 feet in length with a wingspan of 29.5 feet. Notably, a full third of its length consists of an elongated, thin nose cone engineered specifically to break up shockwaves before they can merge.
Powering the experimental plane is a single General Electric F414-GE-100 engine, a model commonly utilized in F/A-18 Super Hornets. In a departure from traditional aircraft design, this engine is mounted on top of the fuselage. NASA explains that this top-mounted configuration directs shockwaves upward, preventing them from reaching the ground and disturbing communities below.
Because the elongated nose forces the cockpit to sit low within the fuselage, the X-59 lacks a forward-facing window. To compensate, NASA developed the eXternal Vision System (XVS). This forward-facing multi-camera system feeds a 4K monitor in the cockpit, providing pilots with an augmented reality display of the airspace, traffic, and graphical flight data. The X-59’s inaugural flight took place on October 28, 2025. During that debut, the aircraft flew for about an hour, reaching a maximum speed of 230 mph at 12,000 feet. Following the flight, NASA conducted extensive maintenance and inspections, which included removing the engine and over 70 panels to verify the aircraft’s structural integrity.
The ultimate goal of the Quesst mission is to reach a top cruising speed of Mach 1.4, approximately 925 mph, at an altitude of 55,000 feet. When traditional aircraft break the sound barrier, merging shockwaves create an explosive sonic boom. The X-59 is designed to separate these shockwaves, reducing the noise to a quiet sonic “thump.” NASA estimates this thump will register at around 75 perceived decibels, which is comparable to the sound of a car door closing.
Once the aircraft’s performance is fully validated, NASA plans to fly the X-59 over select U.S. communities. The resulting public response data will be shared with regulators, including the FAA and ICAO, to potentially establish new noise thresholds and lift the decades-old ban on overland commercial supersonic travel.
The retirement of the Concorde in 2003 marked the end of an era for commercial supersonic flight, largely because noise regulations restricted the aircraft to transoceanic routes. If NASA’s Quesst mission succeeds, it could pave the way for a new generation of airliners capable of cutting cross-country or international flight times in half. However, we must emphasize patience in this testing phase. The X-59 is not breaking the sound barrier yet; the current envelope expansion phase is strictly focused on safety and system validation. Actual supersonic acoustic tests remain further down the program’s timeline.

Frequently Asked Questions (FAQ)
The X-59 is an experimental aircraft built by Lockheed Martin’s Skunk Works for NASA’s Quesst mission. It is designed to fly faster than the speed of sound without producing a loud sonic boom.
The aircraft is currently in its “envelope expansion” phase, flying at subsonic speeds (up to 260 mph at 20,000 feet in its second flight). It will gradually be pushed to its ultimate goal of Mach 1.4 (approx. 925 mph) at 55,000 feet in future tests.
The aircraft’s elongated nose, which is necessary to break up sonic shockwaves, obstructs forward visibility. Pilots use a 4K augmented reality camera system called the eXternal Vision System (XVS) to see ahead.Sources
