Within the government , Aquino de Bragança was nicknamed " the submarine " , apparently because of his ability to work behind the scenes . Asked about his political creed , he described himself as an " anti-anti-communist . " Aquino de Bragança died on 19 October 1986 in a Tupolev Tu-134 plane crash in the Lebombo Mountains , near the border between Mozambique and South Africa . With him on board the plane were President Samora Machel and 33 other senior officials of the country he chose to live in and be part of . The causes of the crash were still unclear . Before his death , Bragança worked on the preparations for a meeting between South African Foreign Minister Pik Botha and Samora Machel , which could have resulted in a reduction of conflicts between the two countries
