The South African Airways passenger jet that went down in that region turned out to be an elaborate case of sabotage since it had on board plutonium and rocket fuel (contraband being acquired by agents of the SA government from China and Korea). As it turned out, the rocket fuel got configured as an incendiary device since the US gov and the UN were aware of both materials and that it was destined for SA which had embargoes at the time. Who exactly "modified" the rocket fuel to rig it to explode during the flight is not clear, but thats what happened with the loss of the crew and all passengers as a fire broke out and the cabin filled with smoke over the open ocean.
