All on the aircraft perished from a fire started in the cargo portion of this Boeing 747 "combi" and the focus of the subsequent investigations was on the cargo, as I suppose it should have been. The Boeing 747 combi went the way of the dinosaurs and the case was closed. But there is more to consider here, perhaps it could have been survivable. The aircraft crashed nineteen minutes after the first report of fire. They might have made it to land had they placed a priority on getting the airplane on the ground as soon as possible.

The crew could have benefitted from a good Emergency Vision Assurance System (EVAS) and better "Speed is Life" procedures. Remember, if you don't put the fire out in eight minutes or less, you probably won't. If you don't get the airplane on the ground in fifteen minutes or less, you may not be able to on your own terms.

South African flight 295 took off from Taipei at 14:23, carrying 159 occupants and 6 pallets of cargo in the main deck cargo hold. At 23:49 the crew reported Mauritius Approach control they had a fire on board. An emergency descent to FL140 was carried out. Mauritius ATC cleared the aircraft to FL50, followed by a approach clearance. The captain's response was the last radio contact with SA295. It appeared that a fire had started in the cargo pallet at position PR. The aircraft had somehow lost control, broke up and crashed into the Ocean.
- More than nine hours into the flight and only about 45 minutes before expected arrival in Mauritius, the flight crew reported smoke to Mauritius Approach Control (MRU) and proceeded to declare an emergency. The airplane's fire detection system had detected smoke in the Class B cargo compartment, and an audible alarm was provided in the cockpit. This alarm could be heard on the airplane's cockpit voice recorder (CVR) tape, which was reviewed after the accident. The alarm likely occurred shortly before Flight 295 contacted MRU to report the smoke. Unfortunately, the CVR and the wiring to it were located in the vicinity of the Class B cargo compartment, and damage from the fire rendered the CVR inoperable within eighty seconds after the audible alarm can be heard on the tape. As such, determining precisely how much time elapsed between the alarm and when contact with MRU was made was not possible because the contact with MRU was made after the CVR failed. The time was probably a matter of minutes, during which the flight crew was likely involved in emergency procedures associated with detection of a cargo fire (Emergency checklist for main deck fire smoke) and control of smoke. (Emergency checklist for main deck smoke evacuation)
- Flight 295's initial report of smoke to MRU was made at about 11:49pm. Communications between Flight 295 and MRU continued for about fifteen minutes before contact was lost. These fifteen minutes of communications between Flight 295 and MRU that were recorded by MRU, along with the limited recording from the damaged CVR, provide information about crew activities in the last minutes of the flight. The flight data recorder (FDR) was not recovered from the crash site, but like the CVR was located in the vicinity of the Class B cargo compartment and would have been susceptible to the same kind of fire damage as the CVR.
- Review of the CVR tape and the communications recorded by MRU indicate that the emergency on board developed quickly. Within four seconds of the audible smoke detection warning in the cockpit, an intercom chime can be heard on the CVR tape, possibly indicating that the flight attendants in the passenger cabin had become aware of the fire nearly simultaneously. Another intercom chime occurred about one minute later, possibly a further attempt by the flight attendants to contact the flight crew. Many of the communications with Flight 295 recorded by MRU were related to plans for an emergency landing at Plaisance Airport, but the recording also picked up some of the communications within the cockpit between crewmembers. About two minutes after the first communication with MRU regarding smoke, the pilot reported, "we've lost a lot of electrics, we haven't got anything on the aircraft now," an indication that the fire was likely affecting airplane systems.

Fire of an unknown origin had possibly: 1) incapacitated the crew; 2) caused disorientation of the crew due to thick smoke; 3) caused crew distraction; 4) weakened the aircraft structure, causing an in-flight break-up.; 5) burned through several control cables; 6) caused loss of control due to deformation of the aircraft fuselage.
