Depicted above are the 16 survivors of the Infamous Andes plane crash in 1972. The passengers had to resort to eating their passed away co-passengers to survive 72 days without help. Also in the photograph is a human rib-cage...
I saw this image again yesterday after a few years and got so intrigued by it that I read the entire Wikipedia page, kept reading up on the subject for the past 24 hours, and I just finished watching the I Am Alive: Surviving the Andes Plane Crash documentary (which got recommended everywhere as the best documentary about the events). Can confirm the documentary was really, really good. Go watch this.

There's also a movie and a book about the event, but I haven't read/seen those.
