Amazing Rescue

Wow!

Some quick thoughts:

Never give up (as the searcher or the searchee). Attitude is everything in these scenarios. Chances are that if this woman had given up, she would not have been found alive.

Lost people almost always travel further than you intuitively expect. For that reason, proper SAR techniques (which are used in surprisingly few places) will use past statistics to allocate search resources.

It's always an emergency, even after 3 weeks. Though she was in decent shape when the brothers came across her, she was severely hypothermic when the rescuers got to her. It's probably a good thing that the rescuers flew in as soon as they could.
