Something TERRIFYING Happened To This Submarine

So I assume that everyone else's mind was brought to the recent incident when that notification popped up?

You were 100% right. Of all of the horrors of the ocean, I've never imagined a submarine dragging a boat under by getting caught in a net

For anyone curious since the video author didn’t state it, the first story is about Chinese Submarine 372 in case you’d like to do further reading

It was discovered in the USS Thresher disaster that they were unable to blow the ballast tanks because the air lines for the emergency air became blocked with ice. There were filter screens inside the lines meant to keep debris out of the tanks. When they tried an emergency blow of the ballast tanks, the air moved through the filter screens so fast it caused condensation to form on them which accumulated and froze eventually becoming ice plugs. It's sad when a disaster is the result of misfortunate events.

Im a US Sub Sailor. I was told that the high pressure air lines that blow the balast tanks froze up after they blew the tanks and couldnt get the balast doors to close after that which aided in the Threshers sinking. There was moisture in the high pressure air lines and of course when high pressure air goes rapidly to low pressure, it gets very cold. Cold enough to freeze water in an instant. This is why dessicant is now used for the high pressure air lines in subs.

My father had an incident with a british submarine back in the 80s, he was trawling with another boat and towing the nets between the two vessels when it got snagged and both boats got pulled backward a few hundred feet. Tore the nets apart, and only for that, they would have both sunk. When he went a shore he was telling other fishermen what happened. Most thought he was cracked, but the story did the rounds, and someone he knew contacted him to say he suspected or had seen a british sub being cleard of or dragging fishing nets (not sure on this part), around the same time. The Sheralga was also an Irish fishing vessel sunk in the Irish sea by the birtish Navy. The crew had to be rescued by other vessels in the area and submarine left without lending assistance or acknowledgement of the event ever happening. Took the crew 4 years to receive anything by way of compensation for loss of the boat and livelihoods.

A member of my family was sadly part of the Antares crew. I was only a toddler at the time but growing up it was said the boat was pulled under in around 17 seconds. That's how little time they had. RIP to all lost ❤🏴󠁧󠁢󠁳󠁣󠁴󠁿

Holy crap...The last story is absolutely frightening. That the sub did not have any kind of equipment that would make it able to assess correctly the situation is frightingly shocking - I would never have thought this could happen.

My maternal grandfather, Lieutenant Merrill Collier, was one of the officers who went down with the Thresher. He left behind my grandmother and three young children, including my 6 year old mother and my unborn uncle. Thank you for covering this with such respect; it is a devastating accident that wounded my mother and her family for life, along with all the families of the crew. Edit: Thank you to everyone for your kind hearts and well wishes; they mean so much ♥️ And to those here who don't believe me; that's okay. I know it is true, that's all that matters, and I don't wish anyone ill for their cruel comments. I'm simply sharing my story. Best wishes to all!

Providing a narrative description of visuals for those listening, but not watching, is an exceptional, professional move. Well done.

I remember them doing tests back in the 90s, to figure out why certain ships were just 'lost' without any call for help. One of the reasons was methane gas bursts from the ocean floor. Methane is not as dense as water, and as such, a ship caught in a funnel (burst) of this gas, would sink as fast as if it were falling through air, and even a ship traveling next to it, would not be affected, nor would it hear the disappearance of that ship. There would be hardly a splash, and the unfortunate ship would be on the bottom, then crushed by the returning pressure.

If stranded in water, dont tread unless you have to. Backfloat is far more energy efficient.

As someone who lives on the west coast of Scotland overlooking the Isle of Arran I absolutely remember the boat getting dragged down by the submarine. My brother in law worked on the fishing boats & it brought it all home how awful this was. Those poor men on that boat. It was & is just heartbreaking ❤😢

1:08 can I just mention how thoughtful it was of you to give a little description there for the people who are only listening? I often just listen to stories like this while doing other things, it was very appreciated

Wow, this is crazy. I had no idea that eddies could get so big. That is terrifying. Also the fact that a submarine could drag a fishing boat under in seconds without even realizing.

I am a retired submariner, and spent the last several years of my career as a QA Supervisor at a submarine maintenance facility. You may know that the sinking of the Thresher brought about the SUBSAFE program which imposed strict controls on the construction and maintenance of seawater systems on submarines. Enforcing that program and its standards was my job. I can say that since the Thresher was lost and the SUBSAFE program was implemented, the US Navy has not lost one single boat due to a material failure or improper maintenance. I went to test depth in deep dive boats many times in my career, and I never felt I was in danger. The loss of the Thresher was not in vain. All who had loved ones on the Thresher have my condolences, but the safety of generations of submariners that followed is their legacy.

Just wanted to give you a “thanks” for describing what the picture of the eddy looked like. Most of the time, I’ve got you on while working (I’m an artist) and having a description really helps me follow along without having to put down what I’m doing and rewind.

My paternal grandfather, Lt. Philip Allen, was one of the unfortunate victims of this heartbreaking disaster. It still pains my dad up to this day. The pain of losing his father with little memory of him was one of his angst in his teenage years. Thank you for covering this case with much respect and dedication. You are giving justice to the families of the lost men on the thresher tragedy.

Was wondering when you’d cover the thresher. Was really rough reading the Navy report released a few years back on possible attempts to communicate distress from Thresher’s crew after losing power. Even with SUBSAFE making the sub force one of the safest in the world, the nerves it takes to be a submariner can’t be put into words.

The fact that the military makes mistakes like this trainings is ridiculous honestly how hard would it be to warn people that they are doing a training exercise
