|Stopover||Mendoza International Airport|
Uruguayan Air Force Flight 571 was a chartered flight that crashed on a glacier at an elevation of 3,570 metres (11,710 ft) in the remote Andes. Among the 45 people on board, 28 survived the initial crash. Facing starvation and death, the survivors reluctantly resorted to cannibalism. After 72 days on the glacier, 16 people were rescued.
The flight carrying 19 members of a rugby team, family, supporters, and friends originated in Montevideo, Uruguay and was headed for Santiago, Chile. While crossing the Andes, the inexperienced co-pilot who was in command mistakenly believed they had reached Curicó, Chile, despite instrument readings indicating otherwise. He turned north and began to descend towards what he thought was Pudahuel Airport. Instead, the aircraft struck the mountain, shearing off both wings and the rear of the fuselage. The forward part of the fuselage careened down a steep slope like a toboggan and came to rest on a glacier. Three crew members and more than a quarter of the passengers died in the crash, and several others quickly succumbed to cold and injuries.
On the tenth day after the crash, the survivors learned from a transistor radio that the search had been called off. Faced with starvation and death, those still alive agreed that should they die, the others might consume their bodies in order to live. With no choice, the survivors ate the bodies of their dead friends. Seventeen days after the crash, 27 remained alive when an avalanche filled the rear of the broken fuselage they were using as shelter, killing eight more survivors. The survivors had little food and no source of heat in the harsh conditions. They decided that a few of the strongest people would hike out to seek rescue. Passengers Nando Parrado and Roberto Canessa, lacking mountaineering gear of any kind, climbed from the glacier at 3,570 metres (11,710 ft) to the 4,670 metres (15,320 ft) peak blocking their way west. Over 10 days they trekked about 24 kilometres (15 mi) seeking help. The first person they saw was Chilean arriero Sergio Catalán, who gave them food and then rode for ten hours to alert authorities. The story of the passengers' survival after 72 days drew international attention. The remaining 16 survivors were rescued on 23 December 1972, more than two months after the crash.
The survivors were concerned about what the public and family members of the dead might think about their acts of eating the dead. There was an initial public backlash, but after they explained the pact the survivors made to sacrifice their flesh if they died to help the others survive, the outcry diminished and the families were more understanding. The incident was later known as the Andes flight disaster and, in the Hispanic world, as El Milagro de los Andes (The Miracle of the Andes).

Members of the amateur Old Christians Club rugby union team from Montevideo, Uruguay, were scheduled to play a match against the Old Boys Club, an English rugby team in Santiago, Chile. Club president Daniel Juan chartered an Uruguayan Air Force twin turboprop Fairchild FH-227D to fly the team over the Andes to Santiago. The aircraft carried 40 passengers and 5 crew members. Colonel Julio César Ferradas was an experienced Air Force pilot who had a total of 5,117 flying hours. He was accompanied by co-pilot Lieutenant-Colonel Dante Héctor Lagurara. There were 10 extra seats and the team members invited a few friends and family members to accompany them. When someone cancelled at the last minute, Graziela Mariana bought the seat so she could attend her oldest daughter's wedding.
The aircraft departed Carrasco International Airport on 12 October 1972, but a storm front over the Andes forced them to stop overnight in Mendoza, Argentina. Although there is a direct route from Mendoza to Santiago 200 kilometres (120 mi) to the west, the high mountains require flight levels of 25,000 to 26,000 feet (7,600 to 7,900 m), very close to the FH-227D's maximum operational ceiling of 28,000 feet (8,500 m). Given that the FH-227 aircraft was fully loaded, this route would have required the pilot to very carefully calculate fuel consumption and to avoid the mountains. Instead, it was customary for this type of aircraft to fly a longer 600 kilometres (370 mi), 90-minute U-shaped route from Mendoza south to Malargüe using the A7 airway (known today as UW44). From there aircraft flew west via the G-17 (UB684) airway, crossing Planchón Pass, to the Chilean town of Curicó, and from there north to Santiago.
The weather on 13 October also affected the flight. On that morning, conditions over the Andes had not improved but changes were expected by the early afternoon. The pilot waited and took off at 2:18 PM on Friday 13 October from Mendoza. He flew south from Mendoza towards Malargüe at flight level 180 (FL180, 18,000 feet (5,500 m)). Lagurara radioed the Malargüe airport with their position and told them they would reach 2,515 metres (8,251 ft) high Planchón Pass at 3:21 PM. The pass is the hand-off point for air traffic control from one side of the Andes to the other. At the pass, controllers in Mendoza transfer flight tracking to Pudahuel air traffic control in Santiago, Chile. Once across the mountains in Chile, south of Curicó, aircraft turn north and initiate descent into Pudahuel Airport in Santiago.
Cause of the crash
Pilot Ferradas had flown across the Andes 29 times. On this flight he was training co-pilot Lagurara, who was pilot in command. As they flew through the Andes, clouds obscured the mountains. The aircraft FAU 571 was only four years old and had only 792 airframe hours. The aircraft was regarded by some pilots as underpowered, and had been nicknamed by them as the "lead-sled."
Given the cloud cover, the pilots were flying under instrument meteorological conditions at an altitude of 18,000 feet (5,500 m) (FL180), and could not visually confirm their location. While some reports state the pilot incorrectly estimated his position using dead reckoning, the pilot was relying on radio navigation. The aircraft's VOR/DME instrument displayed to the pilot a digital reading of the distance to the next radio beacon in Curicó. At Planchón Pass, the aircraft still had to travel 60–70 km to reach Curicó. Inexplicably, at 3:21 PM, shortly after transiting the pass, Lagurara contacted Santiago and notified air controllers that he expected to reach Curicó a minute later. The flight time from the pass to Curicó is normally eleven minutes, but only three minutes later the pilot told Santiago that they were passing Curicó and turning north. He requested permission from air traffic control to descend. The controller in Santiago, unaware the flight was still over the Andes, authorized him to descend to 11,500 feet (3,500 m) (FL115). Later analysis of their flight path found the pilot had not only turned too early, but turned on a heading of 014 degrees, when he should have turned to 030 degrees.
As the aircraft descended, severe turbulence tossed the aircraft up and down. Nando Parrado recalled hitting a downdraft causing the plane to drop several hundred feet and out of the clouds. The rugby players joked about the turbulence at first, until some passengers saw that the aircraft was very close to the mountain. "That was probably the moment when the pilots saw the black ridge rising dead ahead."
Roberto Canessa later said he thought the pilot turned north too soon, and began the descent to Santiago, Chile while the aircraft was still high in the Andes. Then, "he began to climb, until the plane was nearly vertical and it began to stall and shake." The aircraft ground collision alarm sounded, alarming all of the passengers.
The pilot applied maximum power in an attempt to gain altitude. Witness accounts and evidence at the scene indicated the plane struck the mountain either two or three times. The pilot was able to bring the aircraft nose over the ridge but at 3:34 pm, the lower part of the tail cone may have clipped the ridge at 4,200 metres (13,800 ft). The next collision severed the right wing. Some evidence indicates it was thrown back with such force that it tore off the vertical stabilizer and the tail cone. When the tail cone was detached, it took with it the rear portion of the fuselage, including two rows of seats in the rear section of the passenger cabin, the galley, baggage hold, vertical stabilizer, and horizontal stabilizers, leaving a gaping hole in the rear of the fuselage. Three passengers, the navigator, and the steward were lost with the tail section.
The aircraft continued forward for a few more seconds when the left wing struck an outcropping at 4,400 meters (14,400 ft), tearing off the wing. One of the propellers sliced through the fuselage as the wing it was attached to was severed. Two passengers were sucked out of the rear of the open fuselage. The front portion of the fuselage flew straight through the air before sliding down the steep slope at 350 kilometres per hour (220 mph) like a high speed toboggan for about 725 metres (2,379 ft) before colliding with a snow bank. The impact against the snow bank crushed the cockpit and the two pilots inside, killing Ferradas.
The plane fuselage came to rest on a glacier at Malargüe Department, Mendoza Province. The unnamed glacier (later named Glaciar de las Lágrimas or Glacier of Tears) is between Cerro Sosneado and 4,280 metres (14,040 ft) high Volcán Tinguiririca, straddling the remote mountainous border between Chile and Argentina. It is south of 4,650 metres (15,260 ft) high Cerro Seler, the mountain they later climbed and which Nando Parrado named after his father. The aircraft was 80 kilometres (50 mi) east of its planned route.at an elevation of 3,570 metres (11,710 ft) in the
Of the 45 people on the aircraft, three passengers and two crew members in the tail section were killed when it broke apart: Lt. Ramón Saúl Martínez, Orvido Ramírez (plane steward), Gaston Costemalle, Alejo Hounié, and Guido Magri. A few seconds later, Daniel Shaw and Carlos Valeta were sucked out of the fuselage as it fell. Valeta actually survived his fall, but stumbled down the snow-covered glacier, fell into deep snow, and was asphyxiated. His body was found by fellow passengers on 14 December.
At least four died from the impact of the fuselage hitting the snow bank, which ripped the remaining seats from their anchors and hurled them to the front of the plane: team physician Dr. Francisco Nicola and his wife Esther Nicola; Eugenia Parrado and Fernando Vazquez (medical student). Pilot Ferradas died instantly when the nose gear compressed the instrument panel against his chest, forcing his head out the window; co-pilot Laguarara was critically injured and trapped in the crushed cockpit. He asked one of the passengers to find his pistol and shoot him, but the passenger declined.
Thirty-three remained alive, although many were seriously or critically injured, with wounds including broken legs which had resulted from the aircraft's seats collapsing forward against the luggage partition and the pilot's cabin.
Gustavo Zerbino and Roberto Canessa, both second-year medical students, acted quickly to assess the severity of people's wounds and treat those they could help most. Nando Parrado had a skull fracture and remained in a coma for three days. Platero had a piece of metal stuck in his abdomen that when removed brought a few inches of intestine with it, but he immediately began helping others. Both of Arturo Nogueira's legs were broken in several places. None of the passengers with compound fractures survived.
Search and rescue
The Chilean Air Search and Rescue Service (SARS) was notified within the hour that the flight was missing. Four planes searched that afternoon until dark. The news of the missing flight reached Uruguayan media about 6:00 PM that evening. Officers of the Chilean SARS listened to the radio transmissions and concluded the aircraft had come down in one of the most remote and inaccessible areas of the Andes. They called on the Andes Rescue Group of Chile (CSA). Unknown to the people on board or the rescuers, the flight had crashed about 21 kilometres (13 mi) from Hotel Termas, an abandoned resort and hot springs that might have provided limited shelter.
On the second day, eleven aircraft from Argentina, Chile and Uruguay searched for the downed flight.  The search area included their location and a few aircraft flew near the crash site. The survivors tried to use lipstick recovered from the luggage to write an SOS on the roof of the aircraft, but they quit after realizing they lacked enough lipstick to make letters visible from the air. They saw three aircraft fly overhead, but were unable to attract their attention, and none of the aircraft spotted the white fuselage against the snow. The harsh conditions gave searchers little hope they would find anyone alive. Search efforts were cancelled after eight days. On October 21, after searching a total of 142 hours and 30 minutes, the searchers concluded there was no hope and terminated the search. They hoped to find the bodies in the spring when the snow melted.
The survivors found a small transistor radio jammed between seats on the aircraft, and Roy Harley improvised a very long antenna using electrical cable from the plane. He heard the news that the search was cancelled on their 11th day on the mountain. Piers Paul Read's book Alive: The Story of the Andes Survivors described the moments after this discovery:
|“||The others who had clustered around Roy, upon hearing the news, began to sob and pray, all except Parrado, who looked calmly up at the mountains which rose to the west. Gustavo [Coco] Nicolich came out of the aircraft and, seeing their faces, knew what they had heard… [Nicolich] climbed through the hole in the wall of suitcases and rugby shirts, crouched at the mouth of the dim tunnel, and looked at the mournful faces which were turned towards him. 'Hey boys,' he shouted, 'there's some good news! We just heard on the radio. They've called off the search.' Inside the crowded aircraft there was silence. As the hopelessness of their predicament enveloped them, they wept. 'Why the hell is that good news?' Paez shouted angrily at Nicolich. 'Because it means,' [Nicolich] said, 'that we're going to get out of here on our own.' The courage of this one boy prevented a flood of total despair.||”|
During the first night, five more people died: co-pilot Lagurara, Francisco Abal, Graziela Mariani, Felipe Maquirriain, and Julio Martinez-Lamas.
The passengers removed the broken seats and other debris from the aircraft and fashioned a crude shelter. The 27 people crammed themselves into the broken fuselage in a space about 2.5 by 3 metres (8 ft 2 in × 9 ft 10 in). To try to keep out some of the cold, they used luggage, seats, and snow to close off the open end of the fuselage. They improvised in other ways. Fito Strauch was the inventor of the group. He devised a way to obtain water in freezing conditions by using sheet metal from under the seats and placing snow on it. The solar collector melted snow which dripped into empty wine bottles. To prevent snow blindness, he improvised sunglasses using the sun visors in the pilot's cabin, wire, and a bra strap. They removed the seat covers which were partially made of wool and used them to keep warm. They used the seat cushions as snow shoes. Marcelo Perez, captain of the rugby team, assumed leadership.
Nando Parrado woke from his coma after three days to learn his 17-year-old sister Susana Parrado was severely injured. He attempted to keep her alive without success, and during the eighth day she succumbed to her injuries. The remaining 27 faced severe difficulties surviving the nights when temperatures dropped to −30 °C (−22 °F). All had lived near the sea; most of the team members had never seen snow before, and none had experience at high altitude. The survivors lacked medical supplies, cold-weather clothing and equipment, food, and only had three sunglasses among them to help prevent snow blindness.
Reluctant turn to cannibalism
The survivors had extremely little food: eight chocolate bars, a tin of mussels, three small jars of jam, a tin of almonds, a few dates, candies, and dried plums, and several bottles of wine. During the days following the crash, they divided this into very small amounts to make their meager supply last as long as possible. Parrado ate a single chocolate-covered peanut over three days.
Even with this strict rationing, their food stock dwindled quickly. There were no natural vegetation or animals on the glacier or nearby snow-covered mountain. The food ran out after a week, and the group tried to eat parts of the airplane like the cotton inside the seats and leather. They got sicker from eating these.
Survivor Roberto Canessa described the decision to eat the pilots and their dead friends and family members:
|“||Our common goal was to survive — but what we lacked was food. We had long since run out of the meagre pickings we’d found on the plane, and there was no vegetation or animal life to be found. After just a few days we were feeling the sensation of our own bodies consuming themselves just to remain alive. Before long we would become too weak to recover from starvation.
We knew the answer, but it was too terrible to contemplate.
The bodies of our friends and team-mates, preserved outside in the snow and ice, contained vital, life-giving protein that could help us survive. But could we do it?
For a long time we agonised. I went out in the snow and prayed to God for guidance. Without His consent, I felt I would be violating the memory of my friends; that I would be stealing their souls.
We wondered whether we were going mad even to contemplate such a thing. Had we turned into brute savages? Or was this the only sane thing to do? Truly, we were pushing the limits of our fear.
The group survived by collectively deciding to eat flesh from the bodies of their dead comrades. This decision was not taken lightly, as most of the dead were classmates, close friends, or relatives. Canessa used broken glass from the aircraft windshield as a cutting tool. He set the example by swallowing the first matchstick-sized strip of frozen flesh. Several others did the same later on. The next day more survivors ate the meat offered them, but a few refused or could not keep it down.
In his memoir, Miracle in the Andes: 72 Days on the Mountain and My Long Trek Home (2006), Nando Parrado wrote about this decision:
|“||At high altitude, the body's caloric needs are astronomical ... we were starving in earnest, with no hope of finding food, but our hunger soon grew so voracious that we searched anyway ... again and again we scoured the fuselage in search of crumbs and morsels. We tried to eat strips of leather torn from pieces of luggage, though we knew that the chemicals they'd been treated with would do us more harm than good. We ripped open seat cushions hoping to find straw, but found only inedible upholstery foam ... Again and again I came to the same conclusion: unless we wanted to eat the clothes we were wearing, there was nothing here but aluminum, plastic, ice, and rock.:94–95||”|
They consumed the bodies of the pilot and co-pilot first, because they didn't know them. Parrado protected the corpses of his sister and mother and they were never eaten. They dried the meat in the sun, which made it more palatable. They were initially so revolted by the experience that they could eat only skin, muscle and fat. When the supply of flesh was diminished, they also ate hearts, lungs and even brains. They knew without rescue that their time was limited.
All of the passengers were Roman Catholic. Some feared eternal damnation. According to Read, some rationalized the act of necrotic cannibalism as equivalent to the Eucharist, the Body and Blood of Jesus Christ under the appearances of bread and wine. Others justified it according to a Bible verse found in John 15:13: "No man hath greater love than this: that he lay down his life for his friends".
Some initially had reservations, though after realizing that it was their only means of staying alive, changed their minds a few days later. Javier Methol and his wife Liliana, the only surviving female passenger, were the last survivors to eat human flesh. She had strong religious convictions and only reluctantly agreed to partake of the flesh after she was told to view it as "a kind of Holy Communion".
Avalanche buries fuselage
Near midnight on 29 October, an avalanche cascaded down on the survivors as they slept, filling the fuselage and killing eight people: Enrique Platero, Liliana Methol, Gustavo Nicolich, Daniel Maspons, Juan Menendez, Diego Storm, Carlos Roque, and Marcelo Perez. The deaths of Perez, the team captain and leader of the survivors, and Liliana Methol, who had nursed the survivors "like a mother and a saint", were extremely discouraging to those remaining alive.
The avalanche completely buried the fuselage and filled the interior to within 1 metre (3 ft 3 in) of the roof. The survivors trapped inside soon realized they were running out of air. Nando Parrado found a metal pole from the luggage racks and was able to poke a hole in the fuselage roof, providing ventilation. With considerable difficulty, on the morning of October 31 they dug a tunnel from the cockpit to the surface, only to encounter a furious blizzard that left them no choice but to stay inside the fuselage.
For three days the remaining survivors were trapped in the extremely cramped space within the fuselage with about 1 metre (3 ft 3 in) headroom, buried alive under several feet of snow with the corpses of their friends. With no other choice, on the third day they resorted to eating the flesh of their newly dead friends.
With Perez dead, cousins Eduardo and Fito Strauch and Daniel Fernández, assumed leadership. They took over harvesting flesh from their deceased friends and distributing it to the others.
Before the avalanche, a few of the survivors became insistent that their only way of survival would be to climb over the mountains and search for help. Because of the co-pilot's dying statement that the aircraft had passed Curicó, the group believed the Chilean countryside was just a few miles away to the west. They were actually more than 89 kilometres (55 mi) to the east, deep in the Andes. The snow that had buried the fuselage gradually melted as summer arrived. Survivors made several brief expeditions in the immediate vicinity of the aircraft in the first few weeks after the crash, but they found that altitude sickness, dehydration, snow blindness, malnourishment, and the extreme cold during the nights made traveling any significant distance an impossible task.
Expedition explores area
The passengers decided that a few members would seek help. Several survivors were determined to join the expedition team, including Roberto Canessa, one of the two medical students, but others were less willing or unsure of their ability to withstand such a physically exhausting ordeal. Numa Turcatti and Antonio Vizintin were chosen to accompany Canessa and Parrado. They were allocated the largest rations of food and the warmest clothes. They were also spared the daily manual labor around the crash site that was essential for the group's survival, so they could build their strength. At Canessa's urging, they waited nearly seven days to allow for higher temperatures.
They hoped to get to Chile to the west, but a large mountain lay west of the crash site, initially persuading them to try heading east first. They hoped that the valley they were in would make a U-turn and allow them to start walking west. On November 15, after several hours walking east, the trio found the largely intact tail section of the aircraft containing the galley about 1 mile (1.6 km) east and downhill of the fuselage. Inside and nearby they found luggage containing a box of chocolates, three meat patties, a bottle of rum, cigarettes, extra clothes, comic books, and a little medicine. They also found the aircraft's two-way radio. The group decided to camp that night inside the tail section. They built a fire and stayed up late reading comic books.
They continued east the next morning. However, on the second night of the expedition, which was their first night sleeping outside, they nearly froze to death. After some debate the next morning, they decided that it would be wiser to return to the tail, remove the aircraft's batteries, and bring them back to the fuselage so they might power up the radio and make an SOS call to Santiago for help.
Upon returning to the tail, the trio found that the 24 kilograms (53 lb) batteries were too heavy to take back to the fuselage, which lay uphill from the tail section. They decided instead that it would be more effective to return to the fuselage and disconnect the radio system from the aircraft's frame, take it back to the tail, and connect it to the batteries. One of the team members, Roy Harley, was an amateur electronics enthusiast, and they recruited his help in the endeavour. Unknown to any of the team members, the aircraft's electrical system used 115 volts AC, while the battery they had located produced 24 volts DC, making the plan futile from the beginning.
After several days of trying to make the radio work, they gave up and returned to the fuselage with the knowledge that they would have to climb out of the mountains if they were to have any hope of being rescued. On the return trip they were struck by a blizzard. Harley lay down to die but Parrado wouldn't let him stop and brought him back to the fuselage.
Three more deaths
On November 15, Arturo Nogueira died, and three days later, Rafael Echavarren died, both from gangrene due to their infected wounds. Numa Turcatti, who couldn't stomach the idea of eating human flesh, died on day 60 (December 11) weighing only 55 pounds (25 kg). Those left knew they would inevitably die if they didn't find help. The survivors heard on the transistor radio that the Uruguayan Air Force had resumed searching for them.
Making a sleeping bag
It was now apparent that the only way out was to climb over the mountains to the west. They also realized that unless they found a way to survive the freezing temperature of the nights, a trek was impossible. The survivors who had found the tail came up with an idea to use insulation from the rear of the fuselage, copper wire, and waterproof fabric that covered the air conditioning of the plane to fashion a sleeping bag.
Nando Parrado described in his book, Miracle in the Andes: 72 Days on the Mountain and My Long Trek Home, how they came up with the idea of making a sleeping bag:
|“||The second challenge would be to protect ourselves from exposure, especially after sundown. At this time of year we could expect daytime temperatures well above freezing, but the nights were still cold enough to kill us, and we knew now that we couldn't expect to find shelter on the open slopes.
We needed a way to survive the long nights without freezing, and the quilted batts of insulation we'd taken from the tail section gave us our solution ... as we brainstormed about the trip, we realized we could sew the patches together to create a large warm quilt. Then we realized that by folding the quilt in half and stitching the seams together, we could create an insulated sleeping bag large enough for all three expeditionaries to sleep in. With the warmth of three bodies trapped by the insulating cloth, we might be able to weather the coldest nights.
Carlitos [Páez] took on the challenge. His mother had taught him to sew when he was a boy, and with the needles and thread from the sewing kit found in his mother's cosmetic case, he began to work ... to speed the progress, Carlitos taught others to sew, and we all took our turns ... Coche [Inciarte], Gustavo [Zerbino], and Fito [Strauch] turned out to be our best and fastest tailors.
After the sleeping bag was completed and Numa Turcatti died, Canessa was still hesitant. While others encouraged Parrado, none would volunteer to go with him. Parrado finally persuaded Canessa to set out, and joined by Vizintín, the three men took to the mountain on 12 December.
On 12 December 1972, two months after the crash, Parrado, Canessa, and Vizintín began to climb the mountain to their west. Based on the aircraft's altimeter, they thought they were at 7,000 feet (2,100 m) when they were actually at about 11,800 feet (3,597 m). And given the pilot's dying statement that they were near Curicó, they believed that they were near the western edge of the Andes. They brought only a three-day supply of meat.
Parrado wore three pairs of jeans and three sweaters over a polo shirt. He wore four pairs of socks wrapped in a plastic shopping bag. They had no technical gear, no map or compass, and no climbing experience. Instead of climbing the saddle to the west that is 1,670 metres (5,480 ft) lower than the peak, they climbed straight up the steep mountain. They thought they would reach the peak in one day. Parrado took the lead and the other two often had to remind him to slow down, although the thin oxygen made it difficult for all of them. During part of the climb, they sunk up to their hips in the snow softened by the summer sun.
It was still bitterly cold, but the sleeping bag allowed them to live through the nights. In the film Stranded, Canessa described how on the first night during the ascent, they had difficulty finding a place to put down the sleeping bag. A storm blew fiercely, and they finally found a spot on a ledge of rock, on the edge of an abyss. Canessa said it was the worst night of his life. The climb was very slow. The survivors at the fuselage watched them climb for three days. On the second day, Canessa thought he saw a road to the east, and tried to persuade Parrado to head in that direction. Parrado disagreed and they argued without reaching a decision.
On the third morning of the trek, Canessa stayed at their camp. Vizintín and Parrado reached the base of a near-vertical wall more than one hundred meters (300 feet) tall encased in snow and ice. Parrado was determined to hike out or die trying. He used a stick from his pack to carve steps in the wall. He gained the summit of the 4,650 metres (15,260 ft) high peak before Vizintín. Thinking he would see the green valleys of Chile to the west, he was stunned to see a vast array of mountain peaks in every direction. They had climbed a mountain on the border of Argentina and Chile, meaning the trekkers were still tens of kilometres from the green valleys of Chile. Vizintín and Parrado rejoined Canessa where they had slept the night before. At sunset, sipping cognac they had found in the tail section, Parrado said, "Roberto, can you imagine how beautiful this would be if we were not dead men?" The next morning, the three men could see that the hike was going to take much longer than they had originally planned. They were running out of food, so Vizintín agreed to return to the crash site. The return was entirely downhill, and using an aircraft seat as a makeshift sleigh, he returned to the crash site in one hour.
Parrado and Canessa took three hours to climb to the summit. When Canessa reached the top and saw nothing but snow-wrapped mountains for miles around them, his first thought was, "We're dead." Parrado saw two smaller peaks on the western horizon that were not covered in snow. A valley at the base of the mountain they stood on wound its way towards the peaks. Parrado was sure this was their way out of the mountains. He refused to give up hope. Canessa agreed to go west. Only much later did Canessa learn that the trail he saw would have gotten them to rescue.
On the summit, Parrado told Cannesa, "We may be walking to our deaths, but I would rather walk to meet my death than wait for it to come to me." Cannesa agreed. "You and I are friends, Nando. We have been through so much. Now let's go die together." They followed the ridge towards the valley and descended a considerable distance.
Parrado and Canessa hiked for several more days. First, they were able to reach the narrow valley that Parrado had seen on the top of the mountain, where they found the source of Río San José, leading to Río Portillo which meets Río Azufre at Maitenes. They followed the river and reached the snowline.
Gradually, there appeared more and more signs of human presence, first some signs of camping, and finally on the ninth day, some cows. When they rested that evening they were very tired, and Canessa seemed unable to proceed further. When he saw some men on the other side of the river, Parrado wrote the following note and threw it across, tied to a rock:
|“||Spanish: Vengo de un avión que cayó en las montañas. Soy uruguayo. Hace 10 días que estamos caminando. Tengo un amigo herido arriba. En el avión quedan 14 personas heridas. Tenemos que salir rápido de aquí y no sabemos cómo. No tenemos comida. Estamos débiles. ¿Cuándo nos van a buscar arriba? Por favor, no podemos ni caminar. ¿Dónde estamos?
English: I come from a plane that fell in the mountains. I am Uruguayan. We have been walking for ten days. I have a wounded friend up there. In the plane there are still fourteen injured people. We have to get out from here quickly and we don't know how. We don't have any food. We are weak. When are you going to come to fetch us? Please, we cannot even walk. Where are we? SOS
The man who found them, Sergio Catalán, read the note and gave them a sign that he understood. He rode on horseback westward for ten hours to bring help. During the trip he saw another arriero on the south side of Río Azufre, and asked him to reach the boys and to bring them to Los Maitenes. Then, he followed the river to its junction with Río Tinguiririca, where after crossing a bridge he was able to reach the narrow route that linked the village of Puente Negro to the holiday resort of Termas del Flaco. Here, he was able to stop a truck and reach the police station at Puente Negro.
They relayed news of the survivors to the Army command in San Fernando, Chile, who contacted the Army in Santiago. Meanwhile, Parrado and Canessa were brought on horseback to Los Maitenes de Curicó, where they were fed and allowed to rest. Unknown to them, they had hiked about 59 kilometres (37 mi) over 10 days. Canessa had lost 44 kilograms (97 lb), almost half of his body weight.
The news that people had survived the crash of Uruguayan Air Force Flight 571 on 13 October had reached the international press, and a flood of reporters who had walked several kilometers began to appear along the route from Puente Negro to Termas del Flaco. The reporters were clamoring to interview Parrado and Canessa about the crash and their survival ordeal.
The Chilean army provided three Bell UH-1 helicopters to assist with the rescue. They flew in heavy cloud cover under instrument conditions to Los Maitenes de Curicó where the army interviewed Parrado and Canessa. When the fog lifted at about noon, Parrado volunteered to lead the helicopters to the crash site. He had brought the pilot's flight chart and guided the helicopters up the mountain to the location of the remaining survivors. One helicopter remained behind in reserve. The pilots were astounded at the difficult terrain the two men had crossed to reach help.
On the afternoon of 22 December 1972, the two helicopters carrying search and rescue personnel finally reached the survivors. The steep terrain only permitted the pilot to touch down with a single skid. Due to the altitude and weight limits, the two helicopters were able to take only half of the survivors. Four members of the search and rescue team volunteered to stay with the seven survivors remaining on the mountain.
The survivors slept a final night in the fuselage with the search and rescue party. A second flight of helicopters arrived the following morning at daybreak. They carried the remaining survivors to hospitals in Santiago for evaluation. They were treated for a variety of conditions, including altitude sickness, dehydration, frostbite, broken bones, scurvy, and malnutrition.
Under normal circumstances, the search and rescue team would have brought back the remains of the dead for interment. But given the circumstances, including that the bodies were located in Argentina, the Chilean rescuers left the bodies at the site until authorities could make the necessary decisions. The Chilean military photographed the bodies and mapped the area. A Catholic Church priest heard the survivors's confessions and told them that they were not condemned for anthropophagy (eating the dead), given in extremis the nature of their survival situation.
Upon being rescued, the survivors initially explained that they had eaten some cheese and other food they had carried with them, and then local plants and herbs. They planned to discuss the details of how they survived, including their cannibalism, in private with their families. But on December 23 news reports of cannibalism were published worldwide, except in Uruguay. On December 26 two pictures taken by members of Cuerpo de Socorro Andino (Andean Relief Corps) of a half-eaten human leg were printed on the front page of two Chilean newspapers, the Chilean newspapers El Mercurio and La Tercera de la Hora, who reported that all survivors resorted to cannibalism. Rumors circulated in Montevideo immediately after the rescue that the survivors had killed some of the others for food.
The survivors held a press conference on 28 December at Stella Maris College in Montevideo, where they recounted the events of the past 72 days. Alfredo Delgado spoke for the survivors. He compared their actions to that of Jesus Christ at the Last Supper, during which He gave his disciples the Eucharist.
Remains buried at site
The authorities and the victims' fathers decided to bury the remains near the site of the crash in a common grave. Thirteen bodies were untouched, another 15 were mostly bone. Twelve men and a Chilean priest were transported to the crash site on 18 January 1973. Family members were not allowed to attend. They dug a grave about .25 to .5 miles (0.40 to 0.80 km) from the aircraft fuselage at a site they thought was safe from avalanche. Close to the grave they built a simple stone altar and staked an orange iron cross on it. They placed a plaque on the pile of rocks inscribed:
El MUNDO A SUS HERMANOS URUGUAYOS
[English: The world to its Uruguayan brothers
They doused the remains of the fuselage in gasoline and set it alight. Only the charred air frame remained. The father of one victim had received word from a survivor that his son wished to be buried at home. Unable to obtain official permission to retrieve his son's body, Ricardo Echavarren mounted an expedition on his own with hired guides. He had prearranged with the priest who had buried his son to mark the bag containing his son's remains. Upon his return to the abandoned Hotel Termas with his son's remains, he was arrested for grave robbing. A federal judge and the local mayor intervened to obtain his release, and Echavarren later obtained legal permission to bury his son.

† Javier Methol was the first survivor to pass away on the 4th of June 2015, 43 years after the crash 
The survivors' courage under extremely adverse conditions were "a beacon of hope to my generation, showing what can be accomplished with persistence and determination in the presence of unsurpassable odds, and set our minds to attain a common aim".
The sixteen survivors remain very close. They have a reunion each year that includes their families.
In 1973, the mothers of the young people who died in the plane crash founded the Our Children Library in Uruguay to promote reading and teaching.
The crash location attracts hundreds of people from all over the world who pay tribute to the victims and survivors and try to understand how they survived.
The trip to the location takes three days. Four-wheel drive vehicles transport travelers from the village of El Sosneado to Puesto Araya, near the abandoned Hotel Termas del Sosneado. From there travelers ride on horseback, though some choose to walk. They stop overnight on the mountain at El Barroso camp. On the third day they reach Las Lágrimas glacier, where the remains of the accident are found.
In March 2006, the families of those aboard the flight had a black obelisk monument built at the crash site memorializing those who lived and died.
In 2007, Chilean arriero Sergio Catalán was interviewed on Chilean television during which he revealed that he had leg (hip) arthrosis. Robert Canessa, who had become a doctor, and other survivors raised funds to pay for a hip replacement operation.
In popular culture
Over the years, survivors have published books, been portrayed in films and television productions, and produced an official website about the event.
- Blair, Clay, Jr. (1973). Survive!. American Heritage Center – Virtual Exhibits. Retrieved 14 October 2012.
- Read, Piers Paul (1974). Alive: The Story of the Andes Survivors. Read's book, based on interview of the survivors and their families, was a critical success and remains a highly popular work of non-fiction. In the book's opening, the survivors explain why they wanted it to be written:
|“||We decided that this book should be written and the truth known because of the many rumors about what happened in the cordillera. We dedicate this story of our suffering and solidarity to those friends who died and to their parents who, at the time when we most needed it, received us with love and understanding.||”|
- Harper published a reprint in 2005, re-titled: Alive: Sixteen Men, Seventy-two Days, and Insurmountable Odds—The Classic Adventure of Survival in the Andes. It includes a revised introduction as well as interviews with Piers Paul Read, Coche Inciarte, and Álvaro Mangino.
- 34 years after the rescue, Nando Parrado published the book Miracle in the Andes: 72 Days on the Mountain and My Long Trek Home (with Vince Rause), which has received positive reviews. In this text, Parrado also touches upon public reaction to this event::247–8
|“||In fact, our survival had become a matter of national pride. Our ordeal was being celebrated as a glorious adventure… I didn't know how to explain to them that there was no glory in those mountains. It was all ugliness and fear and desperation, and the obscenity of watching so many innocent people die. I was also shaken by the sensationalism with which many in the press covered the matter of what we had eaten to survive. Shortly after our rescue, officials of the Catholic Church announced that according to church doctrine we had committed no sin by eating the flesh of the dead. As Roberto had argued on the mountain, they told the world that the sin would have been to allow ourselves to die. More satisfying for me was the fact that many of the parents of the boys who died had publicly expressed their support for us, telling the world they understood and accepted what we had done to survive... despite these gestures, many news reports focused on the matter of our diet, in reckless and exploitive ways. Some newspapers ran lurid headlines above grisly front-page photos. (247–8)||”|
- Canessa, Roberto (Survivor) (2016). I Had to Survive: How a Plane Crash in the Andes Inspired My Calling to Save Lives. In this book, Canessa recalls how the plane crash helped him learn many life lessons about survival, and how his time in the mountains helped renew his motivation to become a doctor. Today, Canessa is a successful pediatric cardiologist in Uruguay.
