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.
That fan is the smell he had earlier, a fan normally gets an electrical smell before it fails. What they did wrong, They did not abort the mission the second they smelled an electrical problem
@@Paxmaxsure but making these hooks removable would b a minimal thing. Since they are just fixed and not robotic. It's kinda stupid to have hooks that you are not going to use in that dive and also can't see.
I'm a commercial diver who's been following you for a couple of years. I don't often say anything but I appreciate what you do and I always give your videos a like. In particular, if you don't know certain details like in this video, you say so. That's honesty and I appreciate that. Your admissions that you don't know every detail inspires trust, not mistrust. Keep up the great work.👍 The thorough dissection you've done of the events in this tragedy is top-shelf. Your channel is a useful learning resource for anyone working underwater at + 1 atmospheric pressure. There are things to be learned on your channel, even by an old veteran like myself.
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.
In 1985, I declined a very generous offer of employment as an underwater pipe welder. I talked to several people that told me horror stories from their time in that field. The pay, although quite substantial, was not enough for me. I nearly died several times during large land based pipe jobs. I later decided to join the U.S. Navy. I think I made the right decision. RIP to all those lost.
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.
The International Maritime Contractors Association states that 1 out of 20 offshore divers is killed on the job over a 10-year span. So bad.. but not no one makes it 5 yrs.. Also... only 10% of the deaths are from drowning. I guess the other risks are electrocution.. diving sickness.. things like that.
Trapped in a cage of metal slowly suffocating must be so demoralizing knowing you can’t really do anything about it other than wait and try and stay conscious while rescuers struggle to reach you in the depths
@@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.
@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. ;)
Never skip repairs, always have a backup system/plan. And if a more experienced crew member says grab a jacket/food/whatever, DO IT! So many of these incidents could be avoided, or not as severe, if people took logical precautions.
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.
@@mactep1 yep. take an engine for example. it can have all the high tech sensors to control detonation, air/fuel, temperature warning etc, but if the owner doesnt check them periodically to make sure they work, thats on them!
Albert Stover is a paternal relative who died shortly before I was born, and until recently I had no idea what happened. It's especially eerie because I've always had a deathly fear of suffocation and deep water for as long as I can remember, even as a small child; yet was also obsessed with Caribbean shipwrecks. But I grew up in the Midwest pretty far away from oceans & shipwrecks, so.... 🤷♂️
@@carolcamp4828 It's certainly given me a lot to think about, since I never really considered that reincarnation might happen along familial lines; I've always figured it was either random or karma-based. It would make more sense, to me at least.
There is a reason why safety protocols exist. They are for your safety. If you disregard them you effectively sign away your life in the event of an accident. Good job 👏
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.
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.
I don't think the scrubber killed them. Seems like time is what killed them. They had no plan or way to survive for being at that depth for that amount of time. Also it was never clear why the men were in the diving compartment in the first place. Was there any purpose for them going down along with the 2 pilots?
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.
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.
@@sujimaynebut didnt the crew also fail to report to the coastguard about the one failing fan making them think tvey had more time than they actually did?
The other guys were in a separate compartment because they were the ones going outside. They never expected to spend the entire time inside the vehicle. The other compartment was where the electronics and control equipment was.
I have watched every video of yours, and for some reason, this one felt hard to watch. From the 'eh' of overlooking the broken scrubber, to the 'suicide hook', to the many failed rescue attempts. Just heartbreaking for the two gents in the dive compartment.
Two guys in the dive compartment should have done the lockout dive when they had the chance. Never pass up any chance to get out in these situations. People have a tendency to down play how bad situations are, we need to learn from these mistakes. If you are ever in a life or death situation you must recognize your few options to make it out as they arise
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.
First impression: You’d think that a standard bit of “emergency equipment” would be some sort of simple bellows that could be fitted to the “fan” end of the scrubber and physically operated by the crew in the event of a fan failure or even a power failure. Edit: Second impression: Why aren’t there divers on the support ship? That’s so insane to me.
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.
@@dhawthorne1634 well said. hand cranking also increases calorie and h20 needs. the increased body temp would be a plus, but erased by the need for more h20 in short supply (ironically...being trapped in it)
It's click-bait-ish to say "this CO2 scrubber killed these men". The scrubber worked exactly ss designed. The CO2 absorber material worked exactly as expected. The air temp dropped more than predicted, faster than predicted, and nobody thought of a way to warm the CO2 absorbent THAT'S what killed everyone.
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.
@@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.
I recognized that square scrubber. That was from Apollo 13. It was the jury rigged way they fit the LEM scrubber filters to the command modules round filter compartment.
Slight issue with your thumbnail its the scrubber from Apollo 13 it did the exact opposite from what you say it saved the entire crew and enabled their return to earth safely it's one of the greatest emergency engineering improviseings in history
You too believe in that Hollywood thriller movie. As I recall it, they almost froze to death too. This while the space ship was exposed to direct sunlight all the time. How could it get so cold then really? Air condition was what they really needed. All kinds of nonsense in that Hollywood action thriller movie Apollo 13.
This shows the difficulty of conducting rescue operations at only 100m depth. My mind flashes to a certain tourist DSV operating near the Titanic, at about 3,500m. If it had gotten stuck on the seafloor with all alive, imagine how much longer it would take to mount a rescue. I don't think the DSV's reserve oxygen would have lasted long enough. -- Deep sea construction divers have suits they can put on to preserve body warmth for as long as possible. This vessel appeared to have nothing of the sort. I'm thinking they would have found them useful.
Those suits are $1.9 K alone; then there's the boots, gloves, hoses and water heater/pumps (on the surface support vessel) to consider. They probably didn't plan for that like a lot of things they obviously didn't plan for.
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.
I don't need other people to decide stuff for me all the time, but should I stop watching this guy? I see comments pointing out issues on all his videos, some of the minor, some of them not, and worry that I dismiss them too quickly being stuck in a sunk cost fallacy. 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.
What was the point of the people going down in the dive compartment? They can’t see much and they weren’t planning to dive (indeed they declined to dive even when it could have saved their lives).
@@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.
most times with episodes you do on folks stuck under water, i'm more upset at the mistakes that were made than scared or something. this event, every time the Tringa had to reposition or another setback added another hour, it just terrified me. i'm glad two of them were able to make it. many thanks as always.
I think sometimes stuff goes wrong in a series in a single event, is fate saying "not today" and we should give whatever were trying to do a go another time.
A smell of burning while underwater and with a faulty fan speaks of immediate danger! They should have mentioned the smell of burning, so the rescue team react with priority!
I see Waterline Stories has a new upload and I immediately grab a sweet tea and a hot meal for my own personal enjoyment for the day!! Best YT channel ever !! 🇷🇺🇬🇧🏴🇺🇸🇷🇺
Everything that could go wrong went wrong. The actual rescue using brute force to snap the hook and line was wonderful. Excellent coverage of this story.
from what he says, I'd say it wasn't the CO2 scrubber that killed anyone. The broken scrubber fan was in the cockpit and they survived fine by basically pulling a bit of an apollo 13 with the scrubber media. If anything, the "passengers" died because their compartment was aluminum and got too cold for the scrubber material to work properly. They were also dressed improperly (despite being warned) and refused to attempt to exit the sub and try to remedy the problem even when their own compartment was at equal pressure for the depth and would have afforded them no extra risk by that point. We all get lax with things we've done a bunch of times, and it was this laxness by the two in the rear chamber (because they weren't planning to dive) that ultimately sealed their fate.
Nice I was there in Key West on the Naval base I was about 6 yrs old and remember seeing that sub on the deck of the ship. After they retrieved it from the wreck. Great video
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."
@dhawthorne1634 No, the lesson is humans go where we please, and if an inferior species has a problem with that we’ll make them extinct. The dodo once complained we were stomping all over their island. Guess what? No more dodo. Hell, pandas are only still alive because they amuse us. So put on your top hat and do your best dance, shark-boys, or you’re next.
I've heard this story at least half a dozen times on youtube to the point where I almost skipped this. Glad I didn't, you somehow added details and story telling that none of the others did. That's genuinely impressive. Like I could gripe about some other videos, especially ones someone like Brick Immortar covered (though, to be fair, his depth on a topic is incredible). I don't want that to sound back handed, this is genuinely impressive to me. Maybe it means nothing to you, but to me, I'm impressed.
From all the sub rescue videos I’ve watch, it always takes ages and many attempts to rescue people.. I think subs need like a weeks worth of baralime and triple redundancy fans for that system.. it always takes at least a day or 2 or 3 to finally rescue a sub…
I love how there's a backups by design just in case because the people who built it cared enough but the operators see ones broken and decide it will be fine who needs a back up its never needed anyway and that's when you've tempted fate and your gonna regret it. If one fails what's stopping the other one failing its proof it happens don't be stupid and just get stuff fixed 99% of these diving accidents can be prevented by maintenance or if you don't feel safe just say your not doing it yeah might do your managers head in and someone else might take the risk and you lose that specific job but there's nothing they can legally do to you cant fire you or anything or if they do your better off get another place that might listen to you or you could probably file a lawsuit or rat to OSHA about it. Just take the reputation of being a pain and carry on living.
After watching the rest of the video, I'm struck at how many times the rescue attempts were aborted when, if the initial dive was aborted in the first place, everyone could have survived.
I myself almost killed a crew of three, while they were going into a deep dive down to 6000-feet, but had to abort at about 2000-feet. I had designed an underwater lamp/light controller, to allow dimming of 1000watt lamps, since they were too bright in many undersea applications. Unfortunately, the controller box was placed directly under an oil pressure line, which was leaking an dripping hydraulic fluid onto the box. The oil hit a couple of electrical components, reduced their heat transfer capacity, and resulted in hydraulic fluid being burned and vaporized. The crew thought they had an internal fire, donned breather masks, and emergency surfaced. Nonetheless, it took them 20+minutes to surface and get fresh air into this submersible. Had they been down at maximum depths, they probably would have run out of breathable air. The investigation cleared me, but the vehicle was rebuilt, to allow a full rise from 6000+feet, with full additional air/mix, and without heaters working, if electrical power was lost...
Production value has gone up. Man is hitting us with these visual transitions. This is sick. Whole little tv show on youtube. The tragedies are unfortunate but I feel like the respect is handled well and with stances focused on getting the facts across
Great story, but also horrific. Originally, I was wondering why the rising air pressure inside couldn't just be vented to the water outside until I realized that the exterior water was under even more pressure. Too bad they can't just put an air fitting on the outside so that it could be connected to an air hose running to the surface.
1.6 bar partial pressure of oxygen isn't quite as dramatic as you make it sound, I know divers who regularly breathe 1.6 bar during decompression, and some even do that during the active part of a dive. That should not have prevented them from going outside to free the vessel. The fact that the gas they brought is not suitable for the depth they are diving to is frankly simply stupid. I know divers who regularly dive to 100m depth (even inside caves) using rebreathers. Sending divers on surface supply gear is also incredibly stupid. Everything that happened is a massive disregard of common sense, safety engineering and procedures, and incredibly poor planning.
Honestly I'd rather go to space in a Boeing than more than about 20m underwater. Maybe some of that is being raised in the desert, maybe some of it's just wanting for a quick death.
I cannot believe how poor the rescue was from the get go. It seems like they just didn’t act well on the situation. Excellent recovery after some thought….
It is frustrating when you consider the billions the armed forces spend yet frequently their fancy equipment doesn't work when needed. Notice how no progress was made until a commercial salvage vehicle showed up.
Am I missing something? The scrubber whose fan failed was only for the pilots compartment, whose occupants survived. The divers compartment was a completely different system.
Noel Todd was on the ship when it first arrived saying it was a risking mission but hands went up by all to save fellow sea mates. No one cared about their own lives to save those men.
10 Atmospheres.... I can't believe they didn't want to just go for the dive. There just wasnt a way to reach them in time. It's tragic. I wonder if anyone had directly communicated the absoluteness of the math. Another excellent video. Thank you. May they rest in peace.
"They're on the north side of the Berry." Shows bow of the Titanic. Okay, so you didn't have a photo of the bow of the Berry. Dude, we woulda let you slide on that. Enough with those Tieffintanic images, lol.
Seems like there should be better systems for keeping people alive considering that every rescue attempt always takes an eternity longer than the air supply.
Why is one of the pics of the C02 Scrubber the pic from Apollo Space Capsule Co2 Scrubber they had to retrofit after the explosion that damaged their o2 supply. (That square box with tap on it was the fix NASA came up with and that picture is just mirror image of the picture taken in 1970's ) (Also Later the pic of large container with white liquid is from Stargate - Universe (tv series) )
Paul you make the most exciting, yet terrifying video's. I find myself holding my breath or wondering what the hell. Love listening to your voice, hope all is well. 😉❤😉❤
A lot of the stock footage/pictures in here have nothing to do with the incident in question, or even diving in general. It would be really neat to put some sort of a caption indicating what the picture is of (titanic, ISS, apollo 13 CO2 scrubber, etc.) to make it a bit easier to keep track of what's going on.
Proceeding without a backup for a Critical (aka 'thing' that keeps you alive) system and entering a trebly hazardous area (underwater/poor visibility/wreck site) is cavalier in the extreme. If a simple off the shelf fan was replaced this entirely avoidable situation could have been averted.
5:08 Lacking maintenance practices seem to be at the heart of many disasters, proceeding with equipment that isn't 100% functional is always rolling a dice.
Imagine designing a system that grabs hold of something, 104 metres under the sea, without having a means to release it! Imagine diving without a back-up fan! Imagine ignoring your skipper, when he advises you to wear warm clothing! Imagine having the means to save yourself but not being willing to leave the diving compartment!
One thing I am not getting, is the issue is the CO2 in your exhalations, and it works worse when it is cold, right? So, you have the pellets, and you wrapped it in a shirt, why not do that and breathe directly through the bundle of pellets? That way the source of the CO2 will go directly into them, also when you inhale, the air will get a second chance to interact with the pellets before entering your body, and the heat of your body/breath will keep the pellets at a good operating temp.
Wow, this highlights the incompetence I see every single day in the world around me as an adult. When younger, I thought adults were at least somewhat competent. Now, I shudder at the idea of my life being in the hands of another adult.
Am i only one think well just blow out your breathe into the filter? Swing it around so air flows etc? Grab 3 hoses tape to it an everyone csn breath in nose out mouth? Seriously odd marine diving doesnt use marines thinking of improvise or dont go home Edit 15:17 he did improvise! Shirt filled w scrubber material held over a ac vent
i really wish there wasn’t so much bad stock and obviously unrelated footage in these videos. if you don’t have footage it’s ok. and if you’re using something else as an example label it. but seeing the bow of the titanic, the diver with tanks fighting the current as you talk about how they have umbelicals was bad but then showing a clapped out ww2 submarine for the USS amberjack that was supposedly on the way to help???? did anyone review that???
On a different note, this is the very reason why no one is going to Mars and back alive, CO2 scrubbers. There are many other reasons as well, but this one appears unsurmountable.
@@pibyte It matters to some audiences. I know a good number of RU-vidrs (myself included) who pride themselves on accuracy on their videos, to the point of voluntarily making corrections. I'm guessing that might have been the first return in a Google image search. The image has now been changed.
Typical government branch is impressively under prepared for any task. It took 4 hours to secure the dive ship? The divers dropped to the wrong place TWICE! AMAZING
like with planes redundancy should be the rule... for everything critical there should be 2 ... so with the scrubbers they could have had a 2nd scrubber + replacements fans or even a hand driven fan...
So compancy and huburis killed them. The fan not working should have prompted a repair so you have 2 fans that way if that one failed you wouldn't be screwed. Two fan systems like this are NOT that complex if the men were able to open the panel locate the problem and even cobble together a replacement by using the scrubber material in front of the AC unit. They should have kept a few extra fans in a storage bin so they could hot swap the broken one out. Second this sub has a design flaw, there's no heater unit. They died because temps fell too low for the scrubbers to work, they should have had a small space heater or some type of heating unit onboard for this occasion lastly The divers were complacent and got themselves killed by NOT wearing their dive gear and only went in with t-shirts and shorts wtf? that was stupid. They'd be alive if they didn't do such a stupid thing because when pressed about diving they could have gotten out of the sub and used their hand tools to free the ship OR use the oxygen tanks attached to their suits to slowly surface themselves. Let this be a lesson to everyone that does a dangerous job that requires you wear PPE ALWAYS WEAR IT better to have it and not need it than to need it and not have it. If they brought their suits they'd be alive right now
LIKE THEY USED TO TELL US IN THE NAVY, COMPLACENCY KILLS, SADLY IT'S TRUE IN THIS INSTANCE. THEY SHOULD HAVE NEVER DECENDED WITH ONLY ONE SCRUBBER. CONDOLENCES TO THE FAMILIES OF THE LOST
