On October 13, 1972, a chartered turboprop carrying a Uruguayan amateur rugby team, their families, and supporters slammed into a remote ridge of the Andes Mountains. What followed was a 72-day ordeal of freezing temperatures, starvation, an active avalanche, and unimaginable psychological strain. Known worldwide as the Andes flight disaster or the Miracle of the Andes, this event remains one of the most astonishing records of human endurance in aviation history.
Understanding how sixteen people made it off that mountain alive requires looking past Hollywood dramatizations to examine the navigation errors, the grueling daily reality inside a shattered fuselage, and the ultimate 10-day mountain trek that broke the deadlock.
The Fateful Flight and Immediate Crash
The journey began in Montevideo, Uruguay, where the Old Christians Club rugby team chartered a Uruguayan Air Force Fairchild Hiller FH-227 to fly them across the Andes to Santiago, Chile. On board were 45 people, including five crew members and numerous young players in their late teens and early twenties.
Bad weather forced the plane to stop overnight in Mendoza, Argentina. The next day, the flight resumed, but heavy cloud cover obscured the pilots' vision. Compounding the danger, the co-pilot miscalculated their geographic position, believing they had already cleared the mountain range and reached Curicó, Chile. He radioed air traffic control for permission to descend.
Instead of descending into the valley, the plane plunged straight down into a treacherous, snow-choked valley deep inside the Argentine Andes.
- The Impact: The aircraft clipped a sharp ridge at roughly 11,500 feet, shearing off both wings and the tail section.
- Initial Casualties: The fuselage slid down a steep snow slope before coming to a stop. Twelve people died on impact or during the immediate aftermath, leaving 33 survivors, many with severe injuries like broken legs and internal trauma.
Surviving Inside the Fuselage
The remaining passengers found themselves stranded in a hostile sub-zero environment with virtually no alpine gear, minimal medical supplies, and almost no food. Their rations consisted of a few small bars of chocolate, some crackers, and several bottles of wine. Within days, those scraps were entirely gone.
With daytime temperatures dropping far below freezing and bitter winds howling through the broken aircraft shell, the group organized themselves under the leadership of natural leaders like Marcelo Pérez and medical students Roberto Canessa and Gustavo Zerbino. They converted the hollowed-out fuselage into a makeshift shelter, blocking the open end with luggage and seats.
The Grimmer Reality of Nutrition
By the tenth day, starvation set in. Surrounded by miles of barren snow and ice, hunting yielded zero results. Recognizing that death was certain without sustenance, the survivors faced a profound moral and psychological dilemma. Bound by their Catholic faith and deep friendships with the deceased, they debated the only available source of protein: the bodies of their fallen friends.
Canessa and others reasoned that consuming the flesh was a matter of pure survival rather than desecration. Over the coming weeks, this pragmatic decision kept the group alive, though the emotional weight remained heavy throughout their isolation.
The Search Called Off and the Avalanche Disaster
Unbeknownst to the passengers, multiple international search teams from Chile, Argentina, and Uruguay scanned the mountains. However, the white fuselage of the Fairchild merged invisibly into the snowpack, and the pilots' initial miscalculation meant rescue planes searched the wrong corridor.
On October 21—just eight days after the crash—authorities officially called off the aerial search, concluding that no one could have survived the impact and subsequent freezing temperatures. When the survivors heard a radio broadcast announcing that search efforts had ended, despair threatened to overwhelm them.
To make matters worse, a massive avalanche struck the fuselage on the night of October 29 while everyone slept. Snow filled the cabin, suffocating eight more people and trapping the remaining survivors in darkness for three days before they managed to dig a tunnel out.
The Epic Ten-Day Trek for Rescue
By December, the weather warmed slightly, melting the snowpack around the wreckage and convincing the group that waiting passively meant certain death. Realizing that someone had to walk out to find civilization, Fernando "Nando" Parrado and Roberto Canessa volunteered for a desperate expedition.
Equipped with makeshift sleeping bags crafted from insulation material and rugby socks, the two young men climbed out of the valley on December 12, 1972. They assumed they were near the border and that a short climb would reveal the green valleys of Chile. Instead, they discovered an endless expanse of towering mountain peaks.
- The Climb: Facing sheer exhaustion and altitude sickness, Parrado pushed relentlessly upward for three days until he reached the summit of a 15,000-foot peak, only to see more mountains stretching to the horizon.
- The Breakthrough: Refusing to quit, they descended toward a river valley where they finally spotted signs of human life—first trash, and then a Chilean muleteer named Sergio Catalán riding on the opposite bank of the roaring Rio Azopardo.
Because the river drowned out their voices, Catalán threw a rock with paper and a pen attached across the water. Parrado wrote a frantic note explaining that he came from a crashed plane and needed help. Catalán rode hours to the nearest police outpost, setting a military rescue operation into motion.
The Rescue and Legacy
On December 22 and 23, 1972, Chilean Air Force helicopters braved treacherous winds to reach the remote crash site. Because of payload limits at high altitude, the helicopters had to return twice, rescuing the remaining 14 survivors in two waves.
All 16 survivors were flown to safety in Santiago, where medical teams treated them for severe malnutrition, dehydration, and high-altitude frostbite. Their return triggered global media attention, transforming a local tragedy into an enduring symbol of human resilience. Detailed accounts of their experience can be explored further through historical documentation provided by Britannica and archival overviews from the History.com record of Flight 571.
Frequently Asked Questions
Why did the plane crash in the first place?
The crash was caused by a combination of heavy cloud cover, poor visibility, and pilot navigation error. The co-pilot mistakenly believed they had crossed the Andes ridge and requested permission to descend too early, causing the aircraft to strike a mountain slope.
How long were the survivors trapped in the Andes?
The survivors endured 72 days in the high-altitude wilderness, enduring freezing temperatures, an avalanche, and starvation before the final rescue on December 22 and 23, 1972.
How many people survived the ordeal?
Out of the 45 passengers and crew members on board, 12 died in the initial crash, several died from injuries or the subsequent avalanche, and exactly 16 people were rescued alive.
How did the public react to the revelation of cannibalism?
Initially, public reaction was deeply shocked and sensationalized. However, once the survivors held a press conference explaining that consumption of the dead was done strictly out of absolute necessity to preserve life, public understanding shifted, and Catholic authorities publicly absolved them.
