Two of greatest real life survival stories;
In the heart of the sea, the true story of the stove in whale ship Essex, the tale that inspired Melville to write Moby Dick.
Endurance, Earnest Shackleton and his crews almost two year struggle for survival after being shipwrecked in Antarctica. The ships photographer managed to document much of their struggle with chilling (no pun intended) clarity.
Fiction, IIMHO, it's hard to find any survival story to top Jack London, Love of Life.
Enjoy...
