Competing visions for electric propulsion advance.
Bye Aerospace reported that the eFlyer 2 test flight program is advancing with an eye on propeller selection, while ZeroAvia made its first hydrogen-powered flight in the United Kingdom, and Tecnam unveiled a hybrid-electric concept. … …
A new electric mission in mind - Airbus alumni turn attention to eSTOL
Most of the aircraft concepts being designed for urban air mobility take off and land vertically, like helicopters. But a California startup launched in 2019 by five former Airbus staffers who worked on that firm’s Vahana project aims to build something much more like a traditional airplane. … ...

) are short-hop and 500lb cargo - i dont know if we have enough delivery time-critical items to justify this effort. Hydrogen - this is brilliant - as far i remember it was tested and dropped at least twice time in aviation history - last time it was in 1980s - according to theory forged by one of my friends (our industry memory is no longer than just one generation, than we are keep repeating the same trials with similar conclusions) we are approaching time to try this once again. Hydrogen is option positively resonating with my imagination - i see just two small problems: first - source of fuel - right now most effective process accessing hydrogen in large quantity is catalityc decomposition of hydrocabons... doesn't sounds good and environmental friendly, isnt it? Second - something i remember from chemistry lessons in my elementary school - "hydrogen has tendence to leak through most of the seals and after creating stachiometric mixture with air (which is almost every kind of proportion for this material) exploading with characteristic sound"
