Wrote a review of a very fascinating book on Andes crash of 1972, and survival of 16 out of 45 people on board. They were stranded for 72 days in extreme conditions, resorted to cannibalism in order to survive and made a miracle escape. There have been numerous documentaries on this topic, a movie called Alive (1993) starring Ethan Hawke, and some books. https://www.aloksharma.me/blog/book-review-miracle-in-the-andes-by-nando-parrado
