Could condemned combi contact Cocos?

David Klatzow, the South African forensic scientist, has a new book out - 'Steeped in Blood.' One chapter deals with the SA Airways Helderberg crash, when a Boeing combi plunged into the sea near Mauritius, in 1987. He alleges that the Margo Commission which investigated the disaster was a cover up. According to him the fire which ultimately downed the plane started not too long after take-off in Taipei and the SA authorities instructed the pilot continue the flight towards Mauritius. The reason for this was that there was illegal rocket fuel on board (which had caused the fire). As such, if the pilot had landed at an Asian airport the illegal fuel would have been discovered and no insurance would have been paid out. Even though this was in the sanctions period, SA aircraft (designated 'Springbok') would typically call in to flight controllers along the route - aeradios like Lumpur, Darwin and Cocos were easy to hear in Cape Town. In addition, any instructions from SA would also have used an HF frequency and so could have been easily heard by amateurs and professionals. The truth is unlikely to come out but something strange happened on that flight. The QSL is from Cocos Aeradio on the tiny Cocos and Keeling Islands in the Indian Ocean. It refers to a contact with a Springbok flight, heard in 1986 in Cape Town.
