Apartheid and the Helderberg air disaster

David Klatzow is a forensic scientist who was hired to investigate the 1987 Helderberg air disaster, widely considered one of the most covered up in aviation history.

He knows more than anyone in the world about what happened, and says the official story is bunk.

In short, the aircraft was carrying rocket fuel which caught alight mid-air, but the South African government is hiding the truth.

Boeing changed their planes after this crash.
