using hydrogen while doing electrical work. yeah, i dont think who got this idea

I asked a sat supervisor what happened to this..he repied...What oil or gas company wants the hindenburg sailing into their field!!

People comparing these guys to astronauts- are you kidding ? This is far more extreme - the ISS is at 1 atmosphere and they are breathing gases basically as they would on Earth (O2/N2) - these guys are a 500 atmospheres !!! The hydrogen/oxygen mix is very exotic but necessary . Also - God knows how long it takes to come back to 1 atmosphere from that pressure . Astronauts can lick these guy's boots imho ! Edit : 17 days decompress ! Films like these are true gems and it's fantastic we have access to them . Thanks for uploading & for whoever digitised it .

Sad story if you knew what happened to the crews afterwards

As a combat diver myself I can say that this is very easy.

Will anyone ever break the record again. I want to see the record at 32767ft. Or the bottom of challenger deep.

This is no different than working outside the space station

OMG how deep did you dive to see corals😍😍

But that was not the full audio of the radio calls between Estonia and others = other ships, nope!/. But there should be the whole radio transcrpit or something = full audio between the sinking Estonia and other ships. And sorry to say this, the truth, but the Estonia was sank by the NATO countries, all of them, I don't know, but at least the USA and probably Turkey and UK / GB aso = and so on where involved on this huge huge crime!/. The reason, why "They" sank the MS Estonia, was, that Russia might sank It and / or other ship / ships, and / or Russia starting a war, maybe the WW3 between the Sweden at least if not other Countries!/. Why, how so!?? Because Sweden was smugling old / older Soviet Union military stuff from the ex Soviet Union Countries, like probably from the Lithuania and Latvia and possible from Estonia too if not elsewhere!/. And also, there were about 150 Kurds = Kurd Refugees traveling inside in 1 or few Trucks, trying to get to the and in / on the Sweden and USA etc, that they were escaping from the Turkey, probably, for no reason, that I don't know why, but God knows for sure and so on = and they, those drowned Kurds and other people!/. So sorry, to tell you this, the truth, but actualy there is not just 852 dead people, mostly Estonian, but even more Swedish, but 10 Russian and 10 Finns and 1 African etc = aso = and so on, but altogether about 1000 if not little bit over that of dead people inside, yes, still inside the ship!/. Hmh!/. Sad, so so sad and wrong!/. ; /

Here, inhale this explosive mixture of hydrogen and Oxygen 😮

Just simply amazing. I have hundreds of sport/deco/wreck dives. This is a whole 'nother ball game. I always wished I had pursued a commercial diving career when I was able to in my 20s. I was a great welder, a degree in ME, and loved diving and mechanical work. Did a few deco air dives to 200'. Crazy. But I was young and invincible, LOL. My buddy and I got a mild hit diving the wrecks in Truk, first dive that day was the San Francisco I think, 160 or so, didn't tell anyone on the liveaboard because they would have probably req'd evac. Went diving the next day on more wrecks of course! We were "pushing" the tables. That convinced me to be a little more conservative with the tables. You do stupid stuff when you are young. This is not one of the things in life to be stupid with. 530msw = 53 bars = 769 psi! 1% O2 at that pressure gives a partial of 7.7 psi, 0.53 bars. O2 toxicity starts around 1.3 bar. So a safety factor of about 2.5 for that parameter. Then Comex did 701MSW in the chamber. 70 bars, 1015 psi!!! O2 partial of 0.7 bar assuming the same 1% O2 mix. Still a good safety factor. H2/O2 or H2/He/O2 mixes are the only way to do these dives. The thing that would worry the hell out of me is a failure of some sort with the topside mixing/regulating/safety etc etc etc equipment.

All white men. How inequitable could they be.

1971-1991 I was an Army Combat Diver

THANKS FOR THE ADD.

they gonna try to weld the titanic

Did you put this on for me? 😊

saules muzu latvijaj!

Tec dive??

nah bro, Im good.

How amazing

Now I wanna see what happens if you let the air out the diving chamber all of the sudden.

By the late 1980s, the commercial diving industry was already transitioning to robotics, especially for deep diving, due to the economics-it was far less expensive and safer to put a remotely operated vehicle (ROV) at depth for many tasks, instead of a diver. As a result, hydrogen was never “operationalized” as a diving gas, and has remained an exotic vestige of hyperbaric research in search of an application.

Muy bien

I wish I could take this training to improve my own diving skills. Nothing in the recreational diver training world even comes close to this level of intensity (and, thus, quality).

Only 1% oxygen?

no women divers hmmm..

Why dont they have comms

I’ve done a dive to 50 meters on 21%

Brave men who face death at every moment.I salute you all.

If you like this then I HIGHLY recommend reading “Sea Lab” by Ben Hellwarth.

yall in this comments are divers 💀🔫🫲

Das Boot im Video ist U 676. Sieht man am Turmaufbau (Badewanne).

Still looks amazing after over eighty years. My condolences to the families of the fifty two who went down with the vessel when it sank in July of ‘42

What is the depth ?

Nope

Lgbtq watching this: Lgbt can do better

534 meters is deep!!!😬

It takes less time to get back from the moon than it does to decompress from that depth

I’ve even heard passengers who were rescued getting abducted and struck off the survivors list never to be seen again

I wonder why they never continued with this? Is it because of flamability? Because helium is getting more and more expensif. And sure rebreather fix some of it. But diving this deep sounds awsome

А почему он бассейн не проплыл в обратном направлении??

I would be interested to know what bail-out system they used.

They should have left him alone 0:52

👍

👍

These soldiers do not deserve this, it's is painful to watch

The way humans treat each other is disgusting.

these people are true heroes. let us never forget that.

God bless these people, what a terrible ordeal
