1947: BSAA Star Dust

British South American Airways Star Dust disappeared in the Argentine Andes after leaving from Buenos Aires bound for Chile. The plane and 11 occupants have never been found in the subsequent 50 years.

In 1998 an Argentine rock climber found debris from the plane engine at a possible crash site. Imaginative theories of an alien abduction were finally invalid dated in 2000, when more remains and wreckage of the plane were found buried deep in a glacier. But the last communication that the Star Dust sent to air traffic control – the word “STENDEC” in Morse code - has never been deciphered.
