Based on the title of this thread and all that has been posted in the past,I think you should say were Hansie and the two Pilots Murdered..
Sounds like the Conspiracy Theorists are at it in full force. It happens all the time. They are still looking for who killed President Kennedy. KGB? CIA?
It makes for books and movies.
I think after all is said and done it will prove to be just an unfortunate accident with a high profile person involved.
Just another opinion........
