Summary: Controlled flight into terrain due to severe weather conditions
Site: Mount Tupungato, Argentina
Coordinates: 33°22′15″S 69°45′40″W

Flight origin: Morón Airport, Buenos Aires, Argentina
Destination: Los Cerrillos Airport, Santiago, Chile

On 2 August 1947, Star Dust, a British South American Airways (BSAA) Avro Lancastrian airliner on a flight from Buenos Aires, Argentina, to Santiago, Chile, crashed into Mount Tupungato, in the Argentine Andes. An extensive search operation failed to locate the wreckage, despite covering the area of the crash site, and the fate of the aircraft and its occupants remained unknown for over 50 years, giving rise to various conspiracy theories about its disappearance.

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.

The last word in Star Dust's final Morse code transmission to Santiago airport, "STENDEC", was received by the airport control tower four minutes before its planned landing and repeated twice; it has never been satisfactorily explained.

Discovery of wreckage and reconstruction of the crash

In 1998, two Argentine mountaineers climbing Mount Tupungato—about 60 mi (100 km) west-southwest of Mendoza, and about 50 mi (80 km) east of Santiago—found the wreckage of a Rolls-Royce Merlin aircraft engine, along with twisted pieces of metal and shreds of clothing, in the Tupungato Glacier at an elevation of 15,000 ft (4,600 m).

In 2000, an Argentine Army expedition found additional wreckage—including a propeller and wheels (one of which had an intact and inflated tyre)—and noted that the wreckage was well localised, a fact which pointed to a head-on impact with the ground, and which also ruled out a mid-air explosion. Human remains were also recovered, including three torsos, a foot in an ankle boot and a manicured hand. By 2002, the bodies of five of the eight British victims had been identified through DNA testing.
