Ernst Udet
At the Chamonix observatory down in the valley, an astronomer's daughter, Hella Armstrong (Leni Riefenstahl), gazes up at the night sky, helping her father with his work. Every evening she looks forward to Hannes' weather reports and messages—like hearing from a close friend even though they've never met. In addition to her scientific interests, Hella enjoys skiing with her friends in the mountains. One day while skiing with her friends, she meets Ernst Udet (Ernst Udet) in his small aircraft. Together they fly above the clouds to the upper reaches of Mont Blanc. As they approach Hannes' weather station, she drops a small evergreen tree down by parachute with a note introducing herself. Enchanted by the gesture, he carefully decorates his tree for Christmas.
