I think that is a little unfair and I don't think you can make any correlation. It is a bit like saying that all cancer victims ate oranges therefore oranges give you cancer.
There is a nice saying about guiding. It goes:
Your client is trying to kill himself
Your client is trying to kill your other clients
Your client is trying to kill you
The fact there are so few accidents given the number of successful trips is probably more telling.
