The suggesting that participants accept the risks of an activity is a fiction.
It has nothing to do with the individual "accepting the risk"... See my earlier post.
The Court has decided on the evidence that a "reasonable person" would hold the view that recreational flying has an inherent level of risk associated with it such that, if something goes wrong, serious injury or death may result.
It is irrelevant whether the particular passenger "accepted" the risk.
