Why Did the Uruguayan Plane Crash?

The crash of the Uruguayan Air Force Flight 571 is one of the most harrowing survival stories in aviation history. The Fairchild FH-227D aircraft was carrying 45 passengers, including members of a Uruguayan rugby team, their friends, and family. On October 12, 1972, the plane departed from Carrasco International Airport in Montevideo, Uruguay, bound for Santiago, Chile. Tragically, the flight ended in disaster.

The Flight Path and Weather Conditions

The route from Montevideo to Santiago required crossing the Andes mountain range. This is a hazardous passage due to the high altitudes and unpredictable weather patterns. On this particular day, the weather conditions were far from ideal. Storms and turbulence made the journey difficult. The flight crew had to navigate these obstacles while ensuring the plane remained on course.

The Crash

The combination of poor visibility and insufficient navigational aids led the pilots to misjudge their location. They believed they had cleared the Andes when they were still deep within the mountain range. As a result, the aircraft collided with a peak, causing significant damage. The impact tore off the right wing, followed by the tail section, and then the left wing. The fuselage slid down the mountain slope before coming to a stop in a remote area, high in the snow-capped Andes.

Initial Survival

Of the 45 people on board, 12 died immediately from the crash or shortly thereafter due to injuries. The survivors faced an incredibly harsh environment. They had limited food supplies, inadequate clothing, and no way to call for help. The bitter cold and high altitude added to their suffering. The survivors were forced to take extreme measures to stay alive, including rationing the little food they had and melting snow for water.

Waiting for Rescue

The survivors anticipated a swift rescue. Unbeknownst to them, search teams were looking for the wreckage far from the actual crash site, misled by the misreporting of the plane’s location. As days turned into weeks, the survivors came to realize they were on their own.

Radio News

A turning point came when one survivor found a transistor radio in the wreckage. They managed to get it working and tuned in to news broadcasts. It was then they learned that the search had been called off after eight days. This news was demoralizing but also galvanized the group to take matters into their own hands.

Extreme Measures for Survival

Faced with dwindling resources, the survivors made the heart-wrenching decision to resort to cannibalism. They ate the bodies of the deceased passengers preserved in the snow. This drastic measure was essential for their survival in the harsh conditions of the Andes.

The Trek for Help

Nando Parrado and Roberto Canessa, determined to find help, embarked on a perilous trek across the mountains. On December 20, after ten days of navigating treacherous terrain, they encountered a Chilean shepherd. The shepherd informed the authorities, which ultimately led to the rescue of the 14 remaining survivors on December 23, 1972, more than two months after the crash.

Aftermath and Analysis

The crash of Flight 571 resulted from a tragic combination of navigational errors, poor weather, and the challenging topography of the Andes. In examining the causes, aviation experts highlighted the need for better training in mountain flying and improvements in onboard navigational tools to prevent similar tragedies.

Overall, the story of Uruguay Flight 571 stands as a stark reminder of the unpredictability of air travel over mountainous regions and the extraordinary lengths people will go to when driven by the instinct to survive.
