THIS. A lot of people don't know that. It happened due to two steel cables breaking while it was being transported, causing it to fall into the water with the hatch open. Three crew members were inside but they escaped. Once they found it the Aluminaut sub was used to attach cables and nets to it and it was lifted up to 50 feet where it was slowly carried back to Woods Hole. In other words, it sank...but it got better.

[@stephenthompson6982]

When the Alvin sunk the crew had left sandwiches behind & what they discovered was that at the depth the Alvin sunk, the sandwiches were well preserved, which led researchers to believe that the Titanic could also be in a good state of preservation (which due to the iron eating bacteria, Halomonas titanicae, is not the case).

Thank you for an amazing video. I've been interested in this sub since I was a boy in the 80's and with the finding of the Titanic. In awe of what it could do then and even all these years later it still makes my jaw drop after seeing this video. It's a truly stunning work of engineering with no thought missed for safety, even though nothing is without danger or problems. After recent events it has hit home again what an unforgiving environment it is in the depths of the ocean, it's not meant for casual tourism. The amount of dives Alvin has made shows what can be done when there thorough thought and careful maintenance involved. Love the attitude of the guy as well. Top notch. Cheers.

​@@ser_igel It's also smaller, only holding 2 people instead of 3 on Alvin. That alone makes it less capable as a research sub, and therefore means it's also less likely to be supported by the scientific community.

[@gecko-sb1kp]

Apparently less was more...

[@fixman88]

While I was watching this I noticed something that I thought was darkly ironic: Both the Titan and the Alvin have/had devices by Logitech on board. In the case of the Titan it was the infamous game controller that was used to actually control the sub. In the case of the Alvin it's the little white keyboard with integrated trackpad he's using to click on things on the screen where the touch screen was being finicky (I have a slightly fancier version with auto backlit keys). The difference being while the controller was the only thing controlling the Titan the keyboard in the Alvin is completely secondary (as is the computer it's connected to) since all the Alvin's systems are analog and can be controlled by switches.

[@fdsman]

The controller likely had nothing to do with why the Titan imploded, it was merely a symptom of the cost cutting and cavalier attitude Rush took to engineering and safety practices.

[@sparrowlt]

the controller wasnt all that was steering Titan.. they controled the thrusters throught at least one computer.. the controller was just an interface with that that could be moved arround in the cockpit.. you still could pilot it from the computer or other controller (as they had spares). Imagine had they also installed a fancy Thrustmaster warthog joystick

[@fixman88]

[@HydroSnips]

They’d x-ray the heck out of it to ensure no air-pockets or voids etc, and if they found one then they might make a whole new one(?). They weld hull components on nuke subs too and QC-check every millimetre.

[@tomsmith3045]

I think they had to weld it, because it's titanium. As I understand it, each half was hot formed from flat plate into a hemisphere, and then welding together. Tricky to do, but easier and probably more consistent and stronger than trying to cast titanium. Believe titanium has to be vacuum cast because it's so reactive when heated.

[@zackakai5173]

A properly done weld should (in theory, anyway) be as strong as the material around it. I would think the viewing windows would be the weaker points.

[@xmlthegreat]

It's electron beam welded. This type of welding has the weld sometimes stronger than the material around it. The windows are made of really thick acrylic and cone shaped so the pressure pushes them inwards and strengthens the seal.

The Titan iirc had both Titanium and Carbon Fiber for its pressure hull. It sounds good on paper - combine two lightweight yet tough materials - but there's a reason no one in the DSV community recommends using both materials in combination: because their different properties combined actually makes for a hull that doesn't withstand repeated dives under deep sea pressure that well. And since the CEO was cheapskate enough to not perform hull integrity inspections on the submersible after every dive the hull weakened with each dive until it led to the implosion.
