We started this project in the course of the "Global Space Balloon Challenge" 2015 ( http://www.balloonchallenge.org). The balloon reached an altitude of 31'150 m (102'131 ft). Do to a power failure of the board computer the glider has not been released in the stratosphere, so we could not find his camera so far! By the way: we've won the second rank for: "Best Photograph"
