On August 2, 1947, the airliner Star Dust, an Avro Lancastrian carrying six passengers and five crew over the Andes range, crashed into a steep glacier high on the Argentine side of Tupungato. The plane was quickly buried in the resulting avalanche and heavy snowfall that was taking place at the time. The plane lay undetected deep beneath the snow and glacial ice for over 50 years. Its remnants finally re-emerged at the glacier terminus in 2000. Shortly thereafter, an Argentine army expedition discovered the scattered debris and wreckage, collecting some of the evidence for investigation.
