Diver killed on U-boat expedition

[DandyDon]

Hopefully some more information will become available, because although this incident is very tragic and nobody really wants to re-hash details, it is important to understand what happen, so we will hopefully learn from it and avoid it happening to anyone again in the future.

FYI: As for the previous comments about the use of a weight belt, I do not use a weight belt when diving my Dive Rite Rebreather.

And some backplate divers don't wear weights.

What good would be releasing his weights at 70 meters depth? Besides finding the body? You wouldn't help him at all.

We've got:

Medical issue
Overweighted
Ox Tox convulsions

Any other guesses

If a diver seems to be dying at depth and too negative to bring up, I'd would prefer to dump a weight pocket to start an ascent with him. One of my weight pockets typically holds 1/4 of my lead.

It may be futile, but the chances of survival without ascent are nil.

Yes, but no serious tech diver would use integrated weights so the belt would be an all or nothing approach. I also do not understand the phrase "too negative to bring up" at some point he was neutrally buoyant right? a couple of feet higher or a little air dumped and he is positive. I don't think you can make an argument for dumping a weight belt at depth unless you are trying to "make sure he is really dead" just my opinion and it is free

The moderator provided the insight that not all Germans were NAZIs, and that the NAZI party was the same as Republican and Democratic parties in the U.S.

This of course isn't a good insight. Having assumed total control of the state and military and having banned opposition parties, the German National Socialists were nothing like either the Democrats or Republicans. Also, one never saw the US Navy adopt wearing either a donkey or an elephant as part of official uniforms, as the German Navy adopted wearing the insignia of the Nazis, the swastika.

Though I get your point about some being mere "good Germans" and not blind adherents to the Nazi cause.

We are not given info on his kit here. Apparently he was "too negative to bring up" as they left him down.

To address your point specifically, ok - if he is wearing an all-or-nothing belt, or not wearing lead that can be dumped at all because his kit is not buoyant, then some inflation of his system would be the next reasonable approach if he could not be brought up otherwise - which they didn't, so I presume they couldn't. My suspicion is that he was negatively weighted and his gas supply failed, otherwise the divers who tried to help him would have ascended with him one way or another.

Possibly, but maybe they didn't bring him up because he was panicking and they didn't have the gas to stay down with him or couldn't approach him.

The SB moderator needed to do research on totalitarianism.

That's exactly what I was referring to........ie locating the body(easily)........
