Today Boeing has announced the first hydrogen-powered manned flight in aviation history. The aircraft climbed to 3,300 feet over Madrid, Spain, using only electricity and probably several bottles of yummylicious Ribera del Duero wine and Iberian Pata Negra ham rations. The airplane then cruised for 20 minutes at 62mph using only hydrogen cells.
