Boeing has successfully flown the very first hydrogen fuel cell-powered airplane in Madrid, the company announced.
A two-seat Dimona motor-glider with a 16.3 meter (53.5 foot) wingspan was used as the airframe. Built by Diamond Aircraft Industries of Austria, it was modified by BR&TE to include a Proton Exchange Membrane (PEM) fuel cell/lithium-ion battery hybrid system to power an electric motor coupled to a conventional propeller.
Is there a cooler industry R&D shop name than "Phantom Works"? I doubt it.
