H2FLY, a subsidiary of Joby Aviation, has successfully completed the world's first piloted flight of a liquid hydrogen-powered electric aircraft. The flights demonstrate the viability of using cryogenically-stored liquid hydrogen, which enables significantly lower tank weights and volume, leading to longer range. The successful installation and demonstration of flight with liquid hydrogen is believed to increase the range of H2FLY's HY4 demonstrator aircraft from 466 mi to 932 mi. The successful flights are the culmination of Project HEAVEN, a European-government-supported consortium led by H2FLY.
