Chimbu Chuck has said, and I quote...
"You DO NOT know that. I can tell you what they were NOT doing and that is tooling along in IMC and then whacked into 'a mountain' sticking up in front of them.
I do have an idea what MIGHT have happened because it has happened to me - I HAVE seen EXACTLY what they saw in their last seconds but I got away with it. THAT is why I WILL NOT be drawn into any more of your inane posts and why I won't do anything other than help people to understand the challenges they faced."
Do you think you might be "up yourself" a bit, Chuck?
