Star Dust, a British South American Airways Avro Lancastrian, vanished on 2 August 1947 on a Buenos Aires–Santiago flight with 11 people aboard. Its wreckage first emerged from Tupungato Glacier in 1998, when climbers near the 15,000-foot level came across engine parts and metal debris.
The crash buried the aircraft under snow and ice. Over five decades, the glacier carried that debris downhill and concentrated it in a tight field before melt exposed it.
A mountain wreck doesn’t stay where it fell. Fifty-one years after the Star Dust crash, wreckage turned up on the Tupungato Glacier near 15,000 feet — not scattered where it struck, but collected downhill, where the ice had left it. That detail is the underreported part of the 1947 Avro Lancastrian disappearance. The 1998 find didn’t just end a mystery; it made the mountain itself part of the story.
Star Dust, a British South American Airways flight from Buenos Aires to Santiago, went missing on 2 August 1947 with 11 people aboard. For half a century, no crash site existed on any map — the flight simply vanished, and the absence of wreckage fed decades of speculation.
Then in 1998, two Argentine mountaineers climbing the Tupungato Glacier spotted debris. The disappearance became a physical site. But the more interesting story is what moved those pieces downhill, and why they finally surfaced.
What the mountain gave back
In 1998, two Argentine climbers making their way up Tupungato Glacier stumbled onto wreckage. No primary or mainstream source gives a specific calendar date for that find, and the climbers’ names remain unverified. The site sat on Mount Tupungato, about 50 miles east of Santiago — the first confirmed trace of Star Dust in five decades.
One piece identified itself quickly. The Rolls-Royce Merlin engine carried part of the maker’s name on a smashed casing: “OLLS-ROYCE.” That casing linked the debris to the missing Avro Lancastrian operated by British South American Airways.
The 2000 Argentine Army expedition sharpened the picture. The team recovered a propeller and wheels, and the hardware itself told a story. The wheels were still retracted, and the propeller showed engine speeds near cruising power. Nothing suggested an in-flight breakup. The tightly localized debris field pointed to a direct mountain impact — not an explosion — followed by snow burial.
Where the comparison actually gets thin
The glacier-conveyor story is not solely Star Dust’s. Two other aviation wrecks are the closest documented parallels, and both show the same slow downhill drift.
A C-53 Skytrooper Dakota crash-landed on Switzerland’s Gauli Glacier on 19 November 1946. By the time a propeller surfaced in summer 2012, the ice had carried the buried fuselage about four kilometres down-valley. Hot summers kept exposing engine blocks and wing sections years later.
On Alaska’s Colony Glacier, a C-124 Globemaster II that crashed in 1952 was moved roughly 12 miles by the ice. In 2012, melt exposed wreckage and human remains; by 2024, 48 of the 52 people aboard had been identified.

|---|---|---|---|---|
| BSAA Star Dust Avro Lancastrian | Tupungato Glacier, Argentine Andes | 1947 | 1998–2000 | Avalanche burial compacted wreckage into ice; glacier flow carried it downslope; 1998–2000 melt exposed engine, propeller, wheels near 15,000 feet. |

That’s the full, verifiable short list — and it stays short on purpose. Beyond the cases in the table, candidate glacier-recovered crashes usually come with no dependable recovery year and no description of how the ice moved them. Rather than pad the comparison with unsourced examples, we’ve kept it to what primary and mainstream material can actually support.

How ice moves a crash downhill
An aircraft that hits a high snowfield doesn’t just stop — it gets buried. The impact and the avalanche it triggers bury the wreck in loose snow. Season after season, that snow compresses into ice and joins the body of the glacier. Star Dust, wherever it first struck, likely became part of the glacier itself.
From there, the ice does the heavy lifting. A valley glacier flows downhill under its own weight, and debris embedded in it gets carried along — often gathered into medial moraines, the dark bands that form where two ice streams merge. That’s glacial transport of aircraft wreckage in slow motion: the pieces aren’t blasted apart, the ice simply delivers them.
The final step happens downhill, where the ice is warmer and thinner. Glaciologists describe an emergence velocity that pushes buried material back toward the surface, and melt carves out concentrated clusters. Compare C-124: a tire and a shredded yellow life raft eventually sat out in the open on Colony Glacier, each resting on its own pedestal of ice after one hot summer stripped away the cover that had hidden them for decades.
What the ice hasn’t given back yet
Between 1998 and 2000, roughly ten percent of Star Dust’s expected wreckage emerged from the glacier. No new official investigation report or major recovery has been published since the early 2000s. The rest of the aircraft — the bulk of it — is still somewhere in the ice, and more debris could surface as flow and warming continue.
The deeper lesson is operational, not forensic. In 1947, pilots had at best a shaky grasp of high-altitude jet-stream winds, and investigators concluded a miscalculated position likely put the crew into terrain. Today’s crews cross the Andes and the Himalayas with wind models feeding flight-management systems and terrain-awareness warnings. The glacier preserved Star Dust’s remains for half a century; the planning tools that would have kept it from crashing arrived later.
Questions? Answers.
What happened to the Stardust plane?
Star Dust disappeared on 2 August 1947 while flying from Buenos Aires to Santiago. Its wreckage first emerged from Tupungato Glacier in 1998, and by 2000 about ten percent of the expected wreckage had surfaced.
How fast does Tupungato Glacier move?
No published study gives a direct measured surface-flow velocity for Tupungato Glacier. Typical mountain-glacier flow rates range from under 10 metres a year to more than 500 metres a year in exceptional cases. The specific Tupungato rate remains an open question.
Which other glacier-recovered wrecks are comparable to Star Dust?
Two aviation wrecks are the closest documented parallels. A C-53 Dakota crash-landed on Switzerland’s Gauli Glacier on 19 November 1946, and ice carried the wreckage about four kilometres before a propeller surfaced in 2012. A C-124 Globemaster II that crashed in Alaska in 1952 was moved about 12 miles by Colony Glacier before wreckage and remains emerged in 2012.
When is the Gauli Glacier Dakota wreckage expected to reappear?
A propeller from the Dakota first appeared on the glacier in summer 2012. Modelling indicates the fuselage will reappear between 2027 and 2035, and salvage work in 2018 recovered about 2.4 tons of material.
