The aircraft was a Fokker F27 Friendship 400M, registered TC-72 and built in 1981, operated by LADE, the air service run by Argentina's Air Force. As the crew prepared to leave Villa Reynolds, a thunderstorm rose across the route ahead. The departure was delayed and nearly called off. The families, eager to reach the ceremony, hoped to press on, and the flight was cleared to continue along an altered path - lower than usual, swinging south of the storm front over the city of Río Cuarto. It was the kind of choice that looks fatal only in hindsight, made by people weighing a celebration against an inconvenience, with no way to see what waited in the dark.

Around half past eight in the evening, air traffic control in Córdoba lost contact. At nearly the same moment, people living below the aircraft's last known position looked up to see a plane flying low, then watched it strike the mountainside and burst into flame. Flight 072 had hit Cerro Los Linderos at roughly 2,400 metres. Investigators would later classify it as controlled flight into terrain - an aircraft in working order, flown by a capable crew, that simply was not high enough to clear the ground rising in front of it. The captain, Luis Ibarra, and first officer, Daniel Zarza, died with their passengers, along with three other Air Force crew members.

More than 150 people and two helicopters joined the search through the rugged Altas Cumbres. The terrain that had brought the plane down now fought the rescuers at every step; steep ground and foul weather meant it took over eight hours to reach the wreckage, scattered across the dark mountainside. Not every victim could be brought home. The bodies that were recovered were flown back to Comodoro Rivadavia, the Patagonian city many of them had left only that morning, full of plans for the ceremony ahead. More than a thousand mourners gathered for the funeral, and the region observed a day of public mourning. For the towns of Comodoro Rivadavia and Río Gallegos, far to the south, the loss cut deep and lasting - a generation of soldiers, spouses, parents, and children gone in a single evening, families that would carry the absence for decades.

Three decades on, the mountain still holds the memory. On the crash site stands a memorial: a cross five metres tall, fragments of the broken aircraft, and plaques carrying the photographs and names of the dead. What began as a place of grief has slowly become a destination for trekkers, who climb the Sierras to stand among the wreckage and read those names aloud. It is a quiet kind of remembrance - not a polished monument in a city square, but a hard walk into high country, ending at the spot where fifty-three people who had set out for a celebration came to rest instead. The mountain that took them now asks visitors to make an effort to reach them, and in that effort the dead are remembered as what they were: not a statistic, but soldiers and families with names, faces, and a graduation they never saw.
