The Story
On August 2, 1947, BSAA Lancastrian Star Dust departed Buenos Aires for Santiago and disappeared over the Andes. The final Morse code message 'STENDEC' was never deciphered. In 1998, climbers found wreckage on Mount Tupungato, revealing the aircraft had been buried in a glacier. All 11 aboard died on impact.
