The saddest part about this whole story is that it seems if she had searched for her mother she might have saved her. It was probably worse finding out she was still alive after the crash.
"I had nightmares for a long time, for years, and of course the grief about my mother's death and that of the other people came back again and again. The thought Why was I the only survivor? haunts me. It always will." A quote from her in 2010 from http://en.wikipedia.org/wiki/Juliane_Koepcke
How would you get your orientation to know where the other bit of the aircraft was? It's enough of a challenge simply not to walk around in circles when you're isolated.
Yeah, but as far as I can understand they could have been on very remote locations. How do you even search for someone in an unknown, dark, dense forest ?
