South African Airways Flight 295, flown by a Boeing 747 named Helderberg was a commercial flight from Taiwan to South Africa that suffered a catastrophic in-flight fire in the cargo area and crashed into the Indian Ocean east of Mauritius on 28 November 1987, killing everyone on board. An extensive salvage operation was mounted to try to recover the flight data recorders, one of which was recovered from a depth of 4,900 metres (16,100 ft)—the deepest successful salvage operation ever conducted. The official inquiry, headed by Judge Cecil Margo, was unable to determine the cause of the fire, leading to a number of conspiracy theories being advanced in the following years.
South African Airways Flight 295 was a Boeing 747-244B Combi, named The Helderberg (registration ZS-SAS; serial number 22171) that was delivered to the airline in 1980. The aircraft took off on 27 November 1987 from Taipei Chiang Kai Shek International Airport, on a flight to Johannesburg via Mauritius. Dawie Uys served as the captain of the flight.
