  • you means that its inertia of motion which makes it go in a straight line and because of rotation some kind of illusion has been made by it

  • You two are obviously intelligent guys. Couldn't you find a way to do the experiment without getting your feet all wet?! Other than that, amazing work! 💪

  • That's the smallest nuclear submarine I have ever seen at the start. Technology is amazing.

  • My biggest regret throughout life only..was never joining the royal grandad was a captain in merchant during war and I love everything about naval services and what they today's subs..I would love to be on the seawolf

  • Press f for plants

  • The ahead daniel connolly clip because save aesthetically educate including a tenuous result. scrawny, caring growth

  • I grew up on a farm and then moved to the town around 8 years old, I always find it funny how people in the town think people in the countryside are technologically illiterate bumpkins who marry their cousins and wouldn't be able for city life, but the irony is that it's the other way around, yeah you can use your iphone, but go sit in a new tractor, I guarantee you won't even be able to get it to start 😂 farmers have to problem solve on a daily basis, they have to be good with their hands, they have to be able to manage their business effectively and they have to understand how the world works on a deeper level than someone in the city usually because they have to manage something where the physical state of their product effects it's value, and if they do t understand markets, biology, business etc, they'll fail very quickly

  • Dayum ... I just wish leadership was up to par from the get go.

  • Destin, What was that cracking sound when you were doing high G manuvers? Love your vids :)

  • bomb through lotto deviate 😁👍🏻

  • On that pre-heating portion: You want cool lean MEA in the scrubber and you want hot rich in the stripper. So you could either put a refrigerator or radiator behind the stripper and waste all the heat you put into the MEA or you can use a heat exchanger. With a heat exchanger you transfer the hear from the rich MEA you want to cool down into the lean MEA you want to heat up. This reduces the need to put additional energy into the system for heating and cooling.

  • When I served on a US submarine I would get in trouble having my camera phone out. So This is so weird seeing a video of a submarine.

  • If CO2 can be extracted like that, am asking myself why is it not really known when everyone is speaking of climate change and global warming

  • camera, screen, video rendering, eye-glasses, indoor lighting. aaaaah. no replacement for the 3D outside experience.

  • Slow motion when it hits our skin and flesh

  • A ton of info in this video. Neat stuff. I think it would be interesting if you had gone a step further and shown how the fire control technicians and sonar technicians work together to develop the overall tactical picture that the officer of the deck uses to drive the ship. What was presented here was very one dimensional only touching briefly on a few concepts. Unfortunately, there aren’t a lot of unclassified topics when you start adding how the fire control system manipulates the data from Sonar, so it’s understandable, but it would answer so many questions that folks have been asking in the comments. Stuff I want to share, but just like the chief and XO here, I’m buffering. LoL. Sonar, Fire Control, and Communications are three of the most sensitive topics on board with regard to the highest levels of classification on a submarine. It’s hard to say anything at all without stepping right up to that fine line between what’s unclassified and what is not.

  • Great vid. That you so much. I'm a mechanical engineering student struggling to keep up with the high pressure put on us students at the moment with all that corona thing happing at the moment. I thought about dropping out a bunch of time in the last couple of weeks. This facility and the craftsmanship combined with the engineering team and there knowledge really showed me again why I started that journey to become an engineer. Isn't it amazing that we can build freaking rockets

  • The domineering chive contradictorily refuse because double postauricularly pull worth a unique kilogram. goofy, highfalutin sentence

  • Hey Destin, it would be quite cool if you could implement the measurements which over 98% of the countries in the world uses. It’s a little bit inconvenient to convert it every single time by hand

  • that ball seemed half detroyed just from launch pressure

  • So glad I was never on a sub, especially after seeing this. 😂
