No, experience has taught me what's acceptable and what's not.
I do understand your point of view, albiet blunt. I very much appreciate bluntness as opposed to fluff. I don't do anything in the water.. but I ride a motorcycle, and I'm interested in skydive, they are all similiar in philosphy. You are in charge of yourself, always, and you train, and you train, and you train, and you train, and you train, so that when you are <whatever extreme life threatening situation in whatever sport>, your body responds correctly, regardless of all else. Regardless of starving of oxygen 30 feet under water, you know to release your belt and come up, and not panic. In motorcycling, it means so you can obviously react quickly and instantly without hesitation when the situation needs, etc etc etc. Clearly, he should have never been in there, and if you look at the straight facts very specific to his death, ie, you remove how he got in the tank (employed, certain expected precautions taken.. you expect help to be there when you ask for it), you remove any number of things that should have prevented him from getting into the tank in the first place.. perhaps the odds are high that he directly caused it on himself, ie, he did something he shouldn't have done. (obviously, but still you can do everything you are supposed to and die..), be it not release his belt and come up for air, or whatever. But he did probably do the one thing he was taught - if you need help, ask for it via your communication.. the line he was attached to. So maybe he focused his energy on asking for help where he expected to get it, and by that time it was too late for someone without the training for their body to respond appropriately when starved of oxygen in a panic situation.
So why wasn't help there immediately... that is my question.
What was everyone else off doing? How many people were off doing other things, was it just Diver 2, and therefore obviously short handed, and that is why? Or, did someone have the sole task of monitoring this line, and didn't? I am also confused - was this a 3 man team, or a 2 man team? Or was it a 4 man team? Was it only Diver 1 and 2? Is it true or false that someones entire task is to monitor that communication? Or is that one of 100 things going on? What is your take on why this was not a near-miss... shouldn't it have been...
I understand equipment fails.. and **** happens.. but everything should have happened just like it did - except.. shouldn't he have had the help he needed..
