The official ruling that it was faulty wiring in a fuel pump that caused a Boeing 747, 11 mins after take-off, to explode never seemed credible. That, plus eye witness accounts of a streak of light going up, towards the plane, were explained away with the most contorted reasoning.
The plane's altitude had not exceeded the range of a shoulder fired, "Stinger" missile which could easily have been fired from a boat. Other theories are that it was a US Navy missile. Whatever, something smells. We will probably never know, but I am convinced it was a cover up.
For an interesting overview of the incident, check out Nelson DeMille's book, "Night Fall".
A new documentary has brought the subject up again.
