They should have just called it "The Snag O' Matic"

I’m not going on a sub.

Multifunctionality comes at a cost in development and dare I say at a price in use.

You and me both 😨

It seems a bit like riding a motorbike on a 0.5m wide I-beam 500m up in the air at 100m/s between two cliffs. Technically doable, but you have to be 1000% switched on from the first stage of planning right up until you're safely at the other end. Or, y'know... you die. If you're cave diving, add to this night time with only your headlight to light the way, random bends in said I-beam, and the cliffs are far enough apart that you're at the very edge of your fuel capacity. If you're rescue cave diving, add rain, narrow the beam to 0.2m... Yeh, not exactly the safest of jobs.

What gives you that idea? 🫣/sarcasm

Who wouod have thought having to rely on fairly old tech to be in an atmosphere that you shouldn't be in would be dangerous....

That's why we get big Bucks for it..and chick's love a good diver. 😂

Critical fans should be replaced on a schedule.

@@naughtiusmaximus830 no, new parts fail more often than working parts could add an hour limit workload

@@GrandDukeMushroom A burn in would be ideal.

Redundancy probably better. Fans are pretty compact these days. I deal with burnt out power supplies from when the fan fails if you want my “take”.

what is needed is back up fans

Thanks mate. It's really encouraging to hear from a professional. I'm having to learn about humility and it's great to see that it's recognised.

I can’t tell you how much I appreciate your comment. I’m not a diver, but a professional pilot. I’ve flown a lot and instructed a lot and have always tried to be humble and realize someone else may know something I don’t. It is a sign of strength, not weakness, to say “I don’t know” rather than to build a decision on false information or misunderstandings. Much respect and thanks again.

@@HEDGE1011 ​ Thank you so much. I subscribe to a couple of ATC/pilot channels. I find pilot/ATC interactions interesting - sometimes tragic, sometimes funny, and sometimes just downright interesting. In spite of the fact that I'm a nervous flyer and I get scared when I stand on a chair to change a lightbulb, I think there are definite similarities between our two professions. Have a plan. One needs the temperament. You need to be level-headed, and not prone to panic. When all hell is breaking loose you need to keep your wits about you. That has saved my life. Keep your equipment in good working order. Not having your equipment in good working order is your fault. Being injured or killed due to poor equipment is avoidable. Drugs and alcohol can kill you, and probably in your case, others too. I think we probably share all of those traits and more. Thanks again. 👍

@@waterlinestories Great video ! Well done. Just for the info, those tanks are usually 12 or 15 liter tanks filled at 200 bars or up to 300 bars (depending on metal - aluminium vs steel). From a french prof. diver, always a real pleasure to watch your videos.

awesome of you as a professional saying that more people like you are needed in this world

You know what I've already had two panic attacks today, maybe I'll skip this one

@sarasmr4278 3's a charm

@@sarasmr4278 Yeeaaah back when I had anxiety problems I could not watch anything like this. Just honestly skip it, even if it sounds interesting. Keep it together and I hope it gets better mate.

Well they could've just figured out how to use the tried and true "Byford Dolphin" method.

@whatevernamegoeshere3644 much appreciated 💜 I had a recent scare -- turned out fine, but things are all stirred up. I had a panic attack on the climbing wall for the first time today and I sat there in my harness and did my breathing and told myself I was absolutely fine and then I finished the bloody climb so now I am officially a badass thank you very much. ;)

indeed you did!

Holy crap. My uncle very nearly got me started in this industry, and never once warned me. Was he just trying to get a replacement!? Jesus I love the ocean and I find diving so interesting, but I'm honestly glad I stayed away from it. I don't trust myself to not panic, even though I've been through some high pressure emergency situations and done well... being underwater changed all of that. 0 control over your fate.

I met an underwater pipe welder that had been in the gig for 40 years. They had to make new plaques for him every 5 years of service because nobody had ever survived that long. He always told me that safety was the absolute priority in these dire conditions.

Seems like for something like CO2 scrubbers, they should at least have one that's hand cranked considering that mechanical and electrical systems aren't that reliable.

@@ryelor123 Any system is unreliable if you actively choose not to address faults.

Agreed! Knowing one scrubber was faulty, declaring it out loud, and then continuing anyway... It's amazing how quickly people can normalise a hostile environment, and let basic safety standards slip.

That's the problem. They didn't have any safety protocols. No need for a full inspection prior to launch. No need to repair faulty to life support systems before launch. No need to wear diving suits when riding down in the dive compartment. They simply didn't care in the first place. Now the recent Titan sub implosion, that was pure negligence. Which, in my opinion, is even worse than ignorance.

That’s because it is.

Well spotted! :)

The event occurred in 1973 and im guessing no pictures of the exact thing

Came here to say that. That's exactly what that is

but how do you fit a round peg into a square hole again? some duct tape and the cover of the flight manual, right?

Because it’s never used in anger until it is

Lack of maintenance and professionalism.

Because sea farers secretly identify as fish and believe they don't need it!

Goes to show you how likely a Space rescue will be successful!

@@michaelreid2329 Space Travel is much easier than Deep Sea Travel. Hardest part is getting the rocket to space at 28,000 MPH+

That's wild.

It sounds like they were suffering from hypothermia, so their ability to free the Sealink from the cable would have been very difficult, especially wearing just shorts and t shirts. The partial pressure of the oxygen at 1.62 might have killed them anyway. If you are thinking of ascending to the surface, that would be out of the question. From 100 meters they would have to do a decompression ascent like the navy divers. That would be impossible without the proper diving equipment.

I'm confused,we're there wetsuits to perform a lockout dive? R.I.P. but they didn't show respect for task and the pilots advice to dress properly.It just seems strange to be so nonchalant. How much did this rescue cost?

Totally agree. Been in some crazy situations and had to act quick, I remember questioning myself for a minute and saying fuck it and did something I didn't think was going to work. If I didn't make the move I did then there's a good chance I wouldn't still be existing.

@@boathousejoed1126 Yeah as a recreational diver myself, it seems crazy that it spiraled out of control so fast at 300' depth. I would have thought there would be a technical diver or two on the support vessel who could dive down 300' and feet and untangle them with a Trimix setup. They could have been down there in like 10 minutes. Sure it would probably be many hours of deco stops depending on how long they took to untangle it and require quite a few tanks of Trimix. But with the cost of that underwater vessel you would think you would have some sort of rescue plan in place in case something went wrong.

I don't think they even realized they were in a life-or-death situation until it was too late to perform the lockout dive. In hindsight, they obviously should have attempted it despite the risk. They made the fatal assumption that help would arrive long before they depleted their oxygen supply, making it seem like a lockout dive was an unnecessary risk that could potentially make their situation even worse.

The problem is the sheer incompetence of the Coast Guard. If you look into the incident more, it is just obvious that they didn't even need to go there, they were useless and repeatedly failed to get to the submersible because of their lack of organization.

Funsies

That's essentially saying the same thing. Scrubbers don't have infinite capacity. There's only so much CO2 they can absorb. And the scrubbing ability slows with time as the active material is used up. So saying it was the scrubber or saying it was the time, is really the same thing, although saying it is the scrubber makes it sound like it was a catastrophic failure, rather than the inevitable one.

Nope, it was one thing after next.

Keep in mind, this is the early 1970's. We were still using diving bells and pressure suits with air lines and brass helmets. We'd only known how to safely surface from a deep dive for about 50 years and only found out how to treat decompression sickness about a decade prior. The equipment needed to perform deep dives from a surface ship was prohibitively expensive for research vessels and the air supply they had access to, to pump down there would have been toxic at those depths. That's why they had to call in military divers for the rescue attempt. The USCG and USN have a comparatively limitless budget and all of the best equipment of the time already on hand. Ideally, they would have forced anyone in the dive compartment to be ready to leave the compartment in case they needed to address some external issue on the sub, rather than letting them dive in shorts and a t-shirt. "Better to have it and not need it", type of scenario. Unfortunately, they fell on the "need it and not have it" side of that saying. On your first point, a hand cranked fan with gear reduction MIGHT have worked, but the work you'd put in to pumping bellows would increase your CO2 output more than the benefit you'd gain from increased flow through the absorption medium. It would have been more prudent to repair the redundant systems prior to launch and add a resistive heating element on the intake that would have kicked on if the temperature fell near to the minimum effective temperature.

@@dhawthorne1634 - Well said! Thank you for such a thorough and thoughtful response. I agree with your “have it and not need it” SOP being the actual way this emergency could have been averted; having divers in the aft compartment who were ready and able to exit the vehicle to free it from the entanglement is the way. Coming from an aerospace background, I sometimes lose sight of the fact that deep-sea diving is such a recent development and a discipline whose techniques and technologies were driven by government agencies in the same was that space activity was. In so many ways, the deep ocean is a more challenging environment than space. Anyway, thanks again for your insight.

Why not have backup oxygen candles? They were invented in 1945 so they should be good during this time period. Sure they burn super hot... but when freezing with little O2 you might like the temperature increase.

@@ViroMad My guess is because of either cost, stowage or toxicity. They are still rather expensive today. My guess would be a military-only thing back then. They are rather bulky and require a dedicated burn chamber; which a small, deep-dive research vessel couldn't afford the space for. They are meant to be used in larger subs with lower internal pressure and a higher volume of air; which would run you into the same issue of oxygen toxicity as using the inappropriate diving gas that they had on board.

I see what you're saying, but the CO2 scrubber was faultily designed... or else the temp wouldn't have led it to stop scrubbing CO2. Also the fan stopping didn't help either.

It's faulty because the scrubber doesn't have a heater in it.

@@youtubehandlesux The lack of some sort of pre-heater not the same as "faulty". It's an unfortunate design choice with terrible consequences, but that's not the same as "broken." They just never thought of the chamber might get that cold.

Seconded, this really needs to be fixed.

This reminded me of a Randy Feltface joke. "You know, when sharks eat people it's fucked; but it shits me how they immediately go out and kill the shark, like: 'It's gone rogue! It's gone rogue!' "No it hasn't! It's just doing what millions of years of evolution have programed it to do; fucking, swim around eating shit. "'Yeah, but... It came into our bit. This is our bit of the ocean'. "Wha? No. See that bit there, the big, fuckin' wet bit. That's it's bit. "This bit here, this dry bit, that you're standing on WITH YOUR LEGS; you're legs that have evolved to stand on the dry bit. That's you're bit. "You go into it's bit, you're going to GET bit. That's the lesson."

Tell that to whales and dolphins, who came up on to land, went "fuck this" and got back in the ocean.

Because of something that's best described as safety creep. The more often you do procedures, the less dangerous those procedures seem to become and therefore many people get casual with safety procedures. This trip to retrieve that fish trap should have been a breeze and it was, until the unforeseeable happened. And even then it should have been survivable, if not for the very casual disregard of procedures and safety measures, especially by the two men in the diving compartment. Had they been properly dressed and prepared to make an emergency dive if necessary, all of them would probably have survived.

That exact phrase, figuratively, hit me at work today. Changing encoder backup batteries in a Fanuc robot arm. Should take 5 minutes in theory; remove 7 easily accessible screws, pop off a cover, extract 2 battery packs, unplug, plug and slide in 2 new packs, attach cover. In practice, the cover was so stuck on to the robot that we couldnt work it loose. More than 30 minutes later with 2 people, numerous tools and a bit of violence we gave up as not to damage the robot or the cover.

Idiots. That's why. Either in the creation, maintaining or operating or all.

Complacency.

Why were the divers even there, when no dive was planned?

🤣 I'll do my best to not let you wait too long.

@@waterlinestories The way you tell their stories, sometimes I feel claustrophobic, the cave diving stories truly give this affect!! Any loss of life is sad.

I don't need other people to decide stuff for me all the time, but should I stop watching this guy?

I have probably seen every video this guy has put out, and do not want to walk away with an incorrect assessment of any situation, much less one that has cost lives.

You find a picture of a submersible CO2 scrubber then. One that you can freely use in a for profit video. It's not exactly a stock photo you can go and buy the rights to. It's good enough and at least it's a real photo and not some AI creation.
