You are quoting out of contest with the results that people get a wrong impression. The study conclusions are:

I would advice against this ... First it would be quite difficult to undo the top part of the scrubber without disturbing the rest of it unless you also add a retaining nut. Second and most important the reacting section of the scrubber is function of gas density and, therefore, depth. It would...

You are correct, in my haste to reply I should have said the only failure in the decision making ... So I believe you should have stayed on BO. If you have enough gas and not a too big deco obligation why would you go back on the loop? OC is safer. But staying on the loop is the focus of...

Thanks for sharing. Hindsight being always 20/20 I don not see how at the time of starting the chain of events you would have prevented it. The only fail inthe decision making process I see (and only in hindsight) is the will to stay on the loop after initially bailing out. This is normal...

To be precise, helium is an element and cannot be produced (short of nuclear fusion which opens another class of issues), only extracted. Also being so light (2 protons and 2 neutrons) once free in atmosphere tends to migrate to higher layers and once in thermosphere, due to thermodynamic...

This is, in the flying business, akin to tell a recreational private pilot to watch out for the Liquid Oxygen converter leaks when flying inverted and exceeding -4Gs or the hydraulically actuated and electronically stabilised aileron when flying near HIRTAs (High Intensity Radiation Towers Areas).

Are you using this an example of an untrue story? And why this would be "concocted"? Just asking, I am curious. Cheers

“Experience is a dear teacher and fools learn by no other” - Benjamin Franklin. Accident analysis is a tool used in multiple disciplines to identify why people make mistakes. We cannot pretend to do all the mistakes ourselves even because some of them would kill us as they did kill some of the...

Technically those are contributing factors. The cause of the incident was failure to surface before air exhaustion due to ... being unable to exit the overhead environment.

Thanks Ken, would you think it will be made available also after the fact or will it be only live streaming? Cheers

I do not want to derail the thread on boating issues so I will stop commenting on boat styles ... after this :-) You know as well as I do that a fast boat is designed well differently to a boat able to hold any decent sea state ... being 90 miles away with weather that turned sour, 1200 HP will...

Right, that's why putting guns in supermarket makes the US the country with the most people shot (intentionally or by accident). You can put as many HP you want on a boat but the idea should be that it would depend upon the purpose of the boat. A recreational, good weather day out on a 7 meters...

In Italy is law and it is enforced, when they see you. Internationally it is the Alpha flag that means diver down. In costal water depends on jurisdiction on international waters is upon the flag state of the vessel .... (so it is unenforced). But diving in international waters is rare and...

1200 HP on a 12 meters boat? I have to agree with this. BTW I am a licensed boat captain and yacth master I can navigate the world. In this part of the world boating at less than 200 mtrs (600+ feet) from shore has to be done at reduced speed (minimum steerage) and perpendicularly to shore...

Me, you and @beester should meet sometime for an apericena or a spritz. I come at least twice a year in Brescia to fly ... Italy is known for a variety of great food! :D

I beg to differ. As Bob says above, rational thinking is what separates us from (the majority) of other species (there are a few species that show rational thinking caèabilities albeit to a lower level of abstraction). The problem is we have different modalities of making decisions. When we...

I was diving next to it early September in Ponza Italy. Not sure about the chamber but there was a big chopper on top and many water toys ...

Keep in mind that people with far more experience went down to 70 meters bounce dive after the two preceding ones, just to retrieve a grappling hook. If such a lack of judgement can be seen in 2 accomplished tech divers (one is dead and the other now has so many legal problems that is not much...

Yes, and also that at the end they would stay in loose vicinity of earth since, otherwise, we would loose the whole atmosphere and end up like the moon ....

Not really. Each molecule would have a speed which is function of temperature (thermodynamical temperature) which would be non zero if T>0K which is -273 C (wont calculate in F) so as long as you are above absolute 0 degrees ... the gas will keep expanding. Especially if helium. I am not...
