Stbyrud - 1987 a Boeing 747 Helderberg search
In Johan Strümpfer's DEEP OCEAN SEARCH PLANNING - the search for the Boeing 747 of South African Airways Flight 295, he reported that ocean depth was in places over 5 km deep and very mountainous. The wreckage was located at a depth of 4.4 kilometres.
Three debris fields were found: 19°10'30?S 59°38'0?E? / ?19.175°S 59.633333°E? / -19.175; 59.633333? (SA Helderberg Debris Site1).
19°9'53?S 59°38'32?E? / ?19.16472°S 59.64222°E? / -19.16472; 59.64222? (SA Helderberg Debris Site2)
and 19°9'15?S 59°37'25?E? / ?19.15417°S 59.62361°E? / -19.15417; 59.62361? (SA Helderberg Debris Site3).
These locations are 1.5, 2.3 and 2.5 km apart, which indicates that the aircraft broke up before crashing into the Ocean. The extent of the wreckage field was attributed to dispersion of the wreckage during the estimated 80 or more minutes the wreckage took to sink. The aircraft wreckage was found some two months after the accident during the sonar search phase. A further photographic survey and recorder search phase was conducted one year later, at which time the CVR was located.
