Happy Takeoff is building a sub-scale prototype of a planned hydrogen-powered eVTOL aircraft and intends to begin remote-controlled flight tests by March 2021. The Kansas-based startup is working with Oklahoma State University on the 150-pound model as it pursues an ambitious plan to bring a fixed-wing aircraft called Prism to market in 2023.

The company’s engineering team is now defining the design for the Prism based on fresh input it has gathered from prospective customers and also on the latest advances in hydrogen fuel propulsion systems. The aircraft is expected to feature significant differences from an earlier design being developed under the name CitiFlex, which it has now discontinued.
