Throughout history, the most harrowing stories of human survival–like that of the Donner Party in the 1840s–have involved people whose only means of staying alive was to cannibalize the deceased around them. On Friday the 13th of October, 1972, just such a story began when a charter plane carrying 45 rugby team members crashed in the remote Andes Mountains. For 72 days, the world thought they were dead. But what 16 survivors endured was far worse than death, driven to what would become headline-making acts of cannibalism in their struggle for life.
