Mozambique and the Soviet Union rejected the findings of the Margo Commission, led by Justice Cecil Margo. The commission was instituted to investigate into the aircraft crash in which President Samora Machel of Mozambique had been killed. The commission found that the accident had been caused by an error of the crew and that the aircraft had not been lured off course by a decoy beacon as was alleged. Machel was on his way back from an international meeting in Malawi in the presidential Tupolev Tu-134 aircraft when the plane crashed in the Lebombo Mountains, near Mbuzini. Sources: Wallis, F.
