South African Airways Flight 295, flown by a Boeing 747 named Helderberg (Afrikaans: Bright Mountain or Clear Mountain, a mountain range in the SW Cape Province), was a commercial flight 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.
