While the Margo Commission could not determine a definite cause of the fire in the cargo hold that caused the Helderberg disaster, its findings resulted in changes that have reduced the risks of fires on international airliners and enhanced safety of aircraft that carry both passengers and cargo . Rumours about a cover-up of the cause of the Helderberg crash abounded for years - including the suggestion that the fire was caused by illicit cargo of rocket fuel and ammunition. But the credibility of the Margo Commission and its international panel of experts, including Astronaut and Eastern Airlines CEO Frank Borman, suggested otherwise. So did the fact that Margo insisted that the Helderberg's cockpit voice recorder be recovered from the wreckage, which lay on the ocean floor at a depth greater than that of the "Titanic". Years later, South Africa's Truth and Reconciliation Commission extensively investigated the findings of the Margo Commission and found that there was no evidence to justify repudiating the findings.
