ON CHRISTMAS EVE 1971,German teenager Juliane Koepcke was sitting next to her mother on a plane. Juliane had Just graduated from high school in Lima,Peru,and was on her way to Pucallpa in the Amazon region of Peru, where she and her mother would meet up with her father, biologist Hans Koepcke. But the plane never made it. It was struck by lightning, and when the 17-year-old girl looked out the window,she saw the right wing on fire. The last thing Juliane remembered was feeling herself whirling in her seat in midair and then landing in soft vegetation.She ended up on the ground two miles from the crash.
