Thalassamania:
Would you accept the concept that the level of freak accident that is required to kill someone by-and-large varies directly with the diver's training and experience?
As I said, preparation is good.
Thankfully, although obviously heart-rending, sohnje has shared some details of this accident and it appears his friend had good preparation and experience and those around her made every effort to assist when she got into difficulty.
Again, this appears to have been a "freak" (uncommon) accident of aspiration, which caused panic.
With sufficient water aspiration, panic could happen to
any of us.
Speaking generally, in these accident discussions, training, experience and judgment are often important, but hubris is what leads so many to quickly indict the victims as deficient. Sometimes the speculation is informative and instructive, sometimes it's just preening and posturing at the expense of the victim.
From the beginning reports of this accident, it seemed pretty clear this victim and others involved in the accident should have been discussed with a little more humble and reasonable and
caring approach.
