Uruguayan Flight 571 Crashes in the Andes

Context

In the early 1970s, amateur rugby clubs in Uruguay often organized international matches across South America despite limited commercial air service. The Old Christians Club of Montevideo arranged a game in Santiago, Chile, and chartered a military turboprop to transport the team along with family members, friends, and supporters. The flight was one of several such trips that reflected growing regional sports exchanges at the time.

The aircraft, a Fairchild FH-227D operated by the Uruguayan Air Force, departed Montevideo on October 12. Poor weather forced an overnight stop in Mendoza, Argentina, on the eastern side of the Andes. The following morning, with conditions appearing suitable, the plane continued toward its destination across the mountain range that forms the border between Argentina and Chile.

What Happened

On the afternoon of October 13, the plane began its approach to Santiago but descended too soon amid limited visibility. At approximately 3:30 p.m., it struck a remote peak at roughly 11,500 feet in Argentina’s Mendoza Province, losing both wings on impact before sliding into a snowy valley. Twelve people died immediately or within hours from injuries and exposure.

The 33 remaining passengers and crew faced immediate hardships. Many suffered broken bones or other wounds, and the group possessed only the plane’s wreckage for shelter along with scant supplies. Over the following days, additional deaths occurred from injuries, and an avalanche on October 29 killed several more. The survivors organized themselves into teams for tasks such as melting snow for water and searching the debris.

Aftermath

Initial search efforts by Uruguayan and Argentine authorities failed to locate the wreckage because of the plane’s deviation from the expected route and the rugged, high-altitude terrain. With no radio contact and winter conditions setting in, the group was presumed lost. After more than two months, two survivors trekked westward over the mountains, reaching a remote Chilean settlement on December 21 and alerting rescuers.

Helicopters airlifted the remaining survivors to safety on December 22 and 23. The 16 who endured the ordeal returned to Montevideo amid widespread media attention.

Legacy

The episode, soon labeled the Miracle of the Andes, became a widely recounted example of human endurance under extreme isolation and deprivation. Accounts published in books such as Alive and later adapted into films shaped public understanding of group survival dynamics and high-altitude physiology.

The disaster also prompted reviews of navigation procedures for flights over the Andes, contributing to stricter protocols for mountainous routes. It remains a reference point in studies of resilience, decision-making under stress, and the ethical questions that arise in prolonged survival scenarios.
