It is one of the most astonishing survival tales of all time. On October 13, 1972, a young rugby team from Montevideo, Uruguay, boarded a plane for a match in Chile--and then vanished into thin air. Two days before Christmas, 16 of the 45 passengers miraculously resurfaced. They had managed to survive for 72 days after their plane crashed on a remote Andean glacier. Thirty-five years later, the survivors returned to the crash site--known as the Valley of Tears--to recount their harrowing story of defiant endurance and indestructible friendship.
