First 4-seat, hydrogen-cell airplane flies
A four-seat airplane powered by hydrogen fuel cells completed a first test flight this week in Germany, reaching milestones in both size and emissions-free technology. Researchers at the German aerospace center, the DLR, have been developing the HY4 model with a mission to prove that hydrogen can be a viable aviation fuel. The flight from Stuttgart Airport lasted for 10 minutes, with two pilots and two dummies on board, according to an Associated Press report.
