South African Airways Flight 295 was a scheduled international passenger flight from Taoyuan International Airport, Taipei, Taiwan, to Jan Smuts International Airport, Johannesburg, South Africa, with a stopover in Plaisance Airport, Plaine Magnien, Mauritius. On 28 November 1987, the aircraft serving the flight, a Boeing 747-200 Combi named Helderberg, experienced a catastrophic in-flight fire in the cargo area, broke up in mid-air, and crashed into the Indian Ocean east of Mauritius, killing all 159 people on board. An extensive salvage operation was mounted to try to recover the aircraft's flight recorders, one of which was recovered from a depth of 4,900 metres (16,100 ft).

The official inquiry, headed by Judge Cecil Margo, was unable to determine the cause of the fire. This lack of a conclusion led to conspiracy theories being advanced and a subsequent post-apartheid investigation, in the years following the accident.
