H2FLY, a Stuttgart-based developer of hydrogen fuel cell technologies for aircraft, says it set a world record last week for hydrogen-powered passenger aircraft when its demonstrator aircraft, the HY4 flew at an altitude of 7,230 feet.
The company also said it successfully completed a flight between Stuttgart and Friedrichshafen on April 12. This feat marks the first time a hydrogen-electric passenger aircraft has been piloted between two major airports.
