      It was an incredible series and I really enjoyed it. I looked you up on Wiki. I thought I could hear a little Southern in your accent. And what do you know? Huntsville! Home folks! I'm from just across the river! Lots of buddies who went to UAH to school. You do great videos and I look forward to seeing more of them! Take care -- and ROLL TIDE!

    I think that the real reason some of the screens are censored is that the US doesn't want us to know that their Navy personnel do nothing but play Solitaire on their screens.

    I just got done watching the how to surface a submarine video and I have to tell you that this is possibly the best and most interesting video I have ever watched. Having an engineering background I understand some of what you and the men and women of featured in the video were saying. I am amazed that you were allowed to video some of the things that you were. You did a great job at simplifying some of the more complicated things and to convey just how well trained the people on the boat are. It gave me a great sense of pride at the job that these men and women are doing everyday to advance our knowledge of the world and to keep us safe. Thank you!

    That string drooping had NOTHING to do with AIR pressure in the sub, it started drooping because the sides of the sub it was attached to were LITERLALLY being compressed inward making the inside of the sub literally smaller. The hull tensile strength of the Titanium Alloy 6A1-4V used in the construction of most subs is at about 120,000 PSI, so in order for the hull to compress, there have got to be some SERIOUS pressure on the outside of the sub, someone could actually figure out an approximation of their depth simply by calculating the amount of pressure needed in order to compress the hull to make that string droop, just

    Such a cool, calm, confident captain. Then again, I guess the Navy wouldn't want an insecure, overcompensating, FOMO type of personality in command of the deadliest weapons platform on Earth.

    These were great! The combo of people and people skills with science and engineering and people interacting with engineering was outstanding. Love to see you do one or two with David Marquet author of Turn the Ship Around to talk about leadership. That Chief was a brilliant people person. Watching him interact with people was constantly instructive.

  • STSGuitar16

    subs have got to be one of the most complex thing ever built by humans. To think how these things existed nearly 100 years ago (all analog with no computers, mind you) is mind-boggling. I look around and see all these valves, switches, pipes running absolutely everywhere, panels with a million buttons on them, etc. and think how all of those many, many elements must work flawlessly to make it a viable and relatively safe machine/vehicle used on a daily basis. Such an amazing feat of engineering. SO glad destin did this series; I have learned so much and have enjoyed every minute of it. Now we just gotta find a way to get Destin onto the ISS for a couple days and make a vid series on that lol.

  • STSGuitar16

    lol if you think about it, when there is no war going on, these guys are literally just playing like the pinnacle of all make believe "army" games we played as kids

    Incredible footage I'm surprised the us navy even allowed any of that to happen. That was experience of life time for you. Very very few people outside of navy that work on subs ever get to see that.

    best series on yt

  • Hippoatemyzebra

    I work nuclear on land, and I get more mRem per day on accident than this guy did. Literally blown away. One of our people *accidently* had a monitor on when we went on a patio in the sun for 2 hours and got 0.3 mRem. Like, what?!

    The crew referred to “the ship” in the Royal Navy they refer to “the boat” in the Royal Navy the fleet consists of “vessels of the line” ships float on the surface and can carry boats, boats sail below the surface or can be carried on ships.
