While many other companies in the industry are focusing on designing and developing hydrogen-fueled aircraft from scratch, ZeroAvia is gearing up to test its retrofitted Dornier 228 this summer.

The company has partnered with its strategic investor, Shell, to design and build two commercial-scale mobile hydrogen refuelers for use at ZeroAvia’s research and development site in Hollister, California. At ZeroAvia’s test facility in Hollister, Shell will also provide compressed, low-carbon hydrogen supply to the facility and other locations in the Western U.S.

This strategic collaboration will support the development of ZeroAvia’s flight testing program in the U.S. following the arrival of its second Dornier 228 at Hollister last month and will advance the company’s Hydrogen Airport Refueling Ecosystem (HARE) on a larger scale.

NASA and Lockheed Martin’s X-59 is nearing its first flight.

A new video from Lockheed Martin provides a new update on the X-59 aircraft it is developing in collaboration with NASA — and the development seems to be ticking along nicely.

The unnamed passenger can be heard in recordings with air-traffic control saying he had “no idea how to stop the airplane”.
