It is impossible to acuratly analyze an accident without facts of the event.
If the participants here want to discuss hypotheticals then why not just make up some scenarios and then discuss the causes and events involved with this scenario until you've beaten the horse to death.
So far this death has been pinned on; full boats, night diving, lack of equipment maintenance, inexperience, tired crew, bad buddies, distractions etc. For all we know the guy could have had a seizure.
I just find it odd how much effort people put into guessing.
I don't find it odd at all. If you've spent any time in this forum at all, you would know that that's most of what goes on in here. There is usually little to go on until long after the event - so we have no choice but to guess. It's either that, or not talk about it at all.
You are correct that without the actual, verified, facts, we can't
accurately analyze it. But is there value in these types of discussions, even without all the facts? Clearly many of us think so.
As for why we do it - I can't speak for everyone, but I can say for myself, it boils down to: I don't want to die diving. When we talk about all the things that can and do lead to diver fatalities, we are learning, gaining understanding, and in at least some measure, reducing the likelihood that it will happen to us.
As for all the things this death has been "pinned on" - none of us in THIS thread have "pinned" it on anything. We've speculated, postulated, guessed, and discussed. All of those issues CAN lead to diver accidents. Did they lead to this one? We don't know. But just by virtue of reminding each other, and ourselves, that these things CAN lead to accidents, we have taken one more step towards reducing the cases in which it DOES.
If you don't have any interest in these types of discussions, this might not be a good forum for you to spend time in. It seems to bother you. But if you read the rules for this forum, and scroll through the threads in here, you will see that this is primarily what goes on here.
If you find it to be of no value...don't read it! Many of us do.
