MUNICH, Germany (CNN) -- Juliane Koepcke is not someone you'd expect to attract attention. Plainly dressed and wearing prescription glasses, Koepcke sits behind her desk at the Zoological Center in Munich, Germany, where she's a librarian.

Yet this unassuming middle aged woman has one of the most exciting and unbelievable stories of tragedy and survival to tell.

It was Christmas Eve, 1971, when Koepcke, then aged 17, and her mother boarded a Lockheed Electra turboprop for a flight from Lima, Peru, to Pucallpa in the Amazonian rainforest. Her parents, both famous zoologists, ran a research station in the jungle studying wildlife.

"Then we flew into heavy clouds and the plane started shaking. My mother was very nervous. Then to the right we saw a bright flash and the plane went into a nose dive. My mother said, 'This is it!'"

An accident investigation later found that one of the fuel tanks of the Lockheed Electra had been hit by a bolt of lightning which had torn the right wing off.
