On our final part of the Andes Flight Disaster series, we cover the grim realities of survival cannibalism, a violent avalanche, and the miraculous rescue of the survivors of Uruguayan Air Force 571. How do you make the impossible decision to consume the body of another person, who you knew and loved? How do survive a natural disaster with no equipment or help? And after everything you've gone through, how do you gather the strength to hike 38 miles and try to find rescue? We'll learn the answers to all of these questions, straight from the accounts of people who lived through the experience. Tune into this week as Caroline and Alex finish the story of this death-defying journey.
