ABC Primetime Deep, Deep Diver Story

[PerroneFord]

Warren, we talked about hastened breakthrough a bit in class and it really seemed that overbreathing the rig did cause earlier breakthrough. Given what we saw in the video, clearly it wasn't an oxtox. Looked like either hypercapnia, or hypoxia. I agree with you that the oxygen molecules would be more dense at extreme depth, so maybe it wasn't hypoxia that got him. That really doesn't leave many other explanations...

Could he have drained his o2 bottle? Seems unlikely, even though he overstayed his bottom time a bit. Seems he would have had PLENTY left given the amonut of deco he had ahead of him, unless he planned on doing OC deco.

Whoops, my bad. Yes, breakthrough as in the lack of dwell time leading to CO2 laden breathing gas passing through the scrubber - I was thinking about channeling, which is another way breakthrough can happen.

As for the oxygen bottle getting used up, not likely unless he kept bleeding his loop for whatever reason or he burst a hose or something. Oxygen useage again should be based on workload and not depth. Given that he wasn't down for long, I find that unlikely too.

Primetime did the Dave Shaw story last night and his tragic death at Bushman's Hole South Africa. The story and video are here

Really well done show done with proper respect.

Does anyone know of a way to see the whole Video. I am only able to see about 5 minutes.

Thanks
Chris

I'm working on it... should be available middle of next week. I'm taking the commercials and stuff out.

Thanks Perrone

It was an excellent presentation. I thought it was interesting when his wife said she really thought his body should have stayed there for eternity. She didn't want anybody to bring him up but he and the body came up any way.

Heroic? How so? As I was watching it unfold, I was thinking they were making lots of really bad choices.

I make no comment on the "heroic" part, but regarding the choices they made, I think I ought to make a point or two.

I met Dave Shaw a couple of times in Hong Kong. First time he spotted me wearing a polo shirt advertising a tech dive shop and came over to talk (I should just clarify that my tech diving is limited to Adv. Nitrox & rebreathers, neither of which I've used for a while - so I am nowhere near the league of Dave and Don).

From just two discussions with him, I got the feeling that he was probably among the most intensely driven men I'd ever met. He was also deeply religious (although I'm not sure that's related).

Funny thing is that I also knew Jon Bennett reasonably well too, and had a similar feeling with him. He was also an incredibly unassuming and helpful man for his achievements, but you couldn't help notice the quiet confidence he had.

Basically I suppose I'm saying that whilst you're right, Walter, both of these men would have taken the decisions they did based on hundreds of other dives where Murphy hadn't been so close.

These guys would have believed fervently in their own capabilities, and relied on these to get them out of trouble.

Simply put, they were writing some of the rules we are talking about. Changing what they did would mean changing them, which wasn't going to happen.

Well put. This helps us all better understand and connect to people who are, as you say, "writing the rules".

It is a pity that a major news agency does not know their geography as to know the difference between the kalahari and the Karoo desert.

Sorry for opening an old thread but I was wondering if anyone had the full video to watch??

Thanks
