This solo hiker slipped in rugged terrain, broke her pelvis in a fall, and survived four days until SAR found her.

No-one knew she where she was going, or that she was missing, until her friends noticed a lack of Instagram postings.

Perhaps I'm old school; this does not strike me as a practical strategy. But a win is a win, period.
