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.
When a family survived a wilderness crash in California in 1967 in their Cessna 195, only to die while waiting for rescue that never came, their story brought home the need for general-aviation aircraft to carry ELTs, says Alaska author Ross Nixon.
