Star Dust (registration G-AGWH) was a British South American Airways (BSAA) Avro Lancastrian airliner which disappeared in mysterious circumstances on 2 August 1947 during a flight from Buenos Aires, Argentina to Santiago, Chile. A comprehensive search of a wide area (including what is now known to have been the crash site) discovered no wreckage, and the true fate of the aircraft and its passengers and crew remained a mystery for over fifty years. Speculation about the cause and nature of the disappearance of Star Dust included theories of international intrigue, intercorporate sabotage, or abduction by aliens.
