I think the accident you and Rich Lee are referring to was the Japanese lady student, am I right? Frank Robinson discussed that one at the course I was on in the mid-90s. They spent thousands of man-hours analysing the tape and the rest of the evidence and never did come up with an answer.
I think you'll find that if you ask questions, they'll give you a straight answer. Worth emailing Cox or Tim Tucker.
