About the Company

Aether Aerospace

Hybrid hydrogen-electric eVTOL for personal aviation

Aether Aerospace is developing a personal eVTOL aircraft called Project Aether that uses a hybrid hydrogen-electric propulsion system and aims to achieve FAA MOSAIC certification. The aircraft uses batteries for hovering and hydrogen fuel cells for cruise, with the cells recharging the batteries in flight, to offer more than 250 miles of range. It features a tandem tilt-wing with eight ducted fans, fly-by-wire controls, and a whole-aircraft ballistic parachute for safety. The company targets two markets: individual owners who can store the aircraft in a two-car garage for about $195,000, and flight centers that would buy fleets of 10–20 aircraft to rent to Sport Pilots, supported by hydrogen fuel, maintenance, and a booking platform, with the goal of bringing a certificated, on-demand personal air vehicle to market and scaling through fleet-based services.
