Having first flown in 2016, the demonstrator plane has conducted more than 90 test flights and is being used as a development platform for a planned 40-seater hydrogen-electric Dornier 328, which H2FLY says will be introduced in 2025. Alongside claiming the altitude record, in the past week HY4 also carried out a 77-mile journey between Stuttgart and Friedrichshafen, the first time such a flight has been made between two major airports, according to H2FLY.

“This is a remarkable achievement for H2FLY, as no other hydrogen-powered passenger aircraft has flown between two commercial airports to date,” said Prof Dr Josef Kallo, co-founder and CEO of H2FLY.

“We are also thrilled to have set what we believe to be a new world record by reaching an altitude of over 7,000 feet with our HY4 aircraft. We want to thank our long-time partners Stuttgart Airport, University of Ulm, DLR Stuttgart, Friedrichshafen Airport, and AERO Friedrichshafen, for supporting us in our mission to make sustainable travel a reality."
