On October 13th, 1972, Uruguayan Air Force Flight 571 crashed in the Andes while carrying 45 passengers and crew, most of them members of the Old Christians rugby team from the Christian Brothers College of Montevideo, headed to Santiago, Chile for a match. Sixteen survivors would spend up to 72 days in the most harrowing of conditions, resorting to two months of cannibalism to survive. No one should have lived - their story is both horrific and inspiring.
