The British South American Airways (BSAA) Avro Lancastrian airliner (registration G-AGWH) took off from Buenos Aires, Argentina enroute to Santiago, Chile on August 2, 1947.
Star Dust’s final Morse code transmission to Santiago airport, S T E N D E C, was received by the control tower four minutes prior to its planned landing and repeated twice:
… – . -. -.. . -.-.
… – . -. -.. . -.-.
The Morse transmission sounded just like this:
Star Dust — like Malaysian Airlines Flight MH370 and Argentina’s Cadet Flight — was never heard from again.
And what does S T E N D E C mean? No one knew then, no one knows now.
