Author of “Stratonauts: Pioneers Venturing into the Stratosphere”

Manfred “Dutch” von Ehrenfried

« The quest for stratospheric flight is not one to be considered lightly as it is fraught with perils as many have discovered. To attempt it with solar power alone would have been considered folly not too many years ago. But now, there are a few who have captured the sun’s rays with sufficient efficiency that it is now possible to challenge the stratosphere. I will be with the team in spirit and follow your progress with envy. »
