In the late 1990s, pieces of wreckage from the missing aircraft began to emerge from the glacial ice. It is now believed that the crew became confused as to their exact location while flying at high altitudes through the (then poorly understood) jet stream. Mistakenly believing they had already cleared the mountain tops, they started their descent when they were in fact still behind cloud-covered peaks, and Star Dust crashed into Mount Tupungato, killing all aboard and burying itself in snow and ice.
