I came here to mention exactly this. I can't believe how the article misses this fact, even when it includes pictures of her return to the crash site that were actually taken during the filming of Herzog's documentary. For all of HNers interested in this story, the documentary is highly recommendable if you like Herzog's deeply psychoanalytical take when he portrays real life characters and situations.

Other curious fact: Werner Herzog was supposed to take this flight. He missed it.

Haven't seen the Herzog documentary, but I remember seeing this story dramatized in a (West) German movie:

I was maybe 8 or 9 when it was shown on Japanese TV. Amazed it didn't scare me away from air travel for life.
