    @SmarterEveryDay Completely understand that! I know several veterans myself from earlier times, who are greatly wise from their experiences. As an aside note, working in the Oil & Gas and maritime industries; I see a lot of very bright younger people as well. Complete respect and wish all our younger generation possessed this type of knowledge and experience. Our country would be so much better off!

    22:46 Who even uses such low quality ice in 2021? We are living in the future, good people, and in the future we can create crystal clear ice. There is NO reason whatsoever to use cloudy ice to cool a drink in 2021. Where did he even get an ice-machine that produces such low quality product? I mean: one, the ice is opaque (causing a reduced cooling-to-watering-down ratio) and two, the ice is some sort of sausage-shape instead of crisp cubes (causing a visually sub-par drink presentation). It is 2021, humans. We need to up our game! Crystal clear perfect cubes or bust. I hope I never again see cloudy ice-sausages illustrating “ice” in a NOlocal-video. It should at least be marked as “viewer discretion advised”, or more reasonably “this has been identified as disturbing content - do you wish to proceed?”.

    I wonder if you think a contact could be in the shadow zone - you could use some kind of very sensitive hydrogen detector to see hydrogen being released from a sub due to the electrolysis on board - or a sensitive CO2 sensor to see where there's more of that than there should be... but they're probably released in bursts so you could never get a constant position... or something... loving this series!!

    I had a friend that worked at the portsmouth naval shipyard on the reactors. he used to tap hydrogen off the reactor, put it in a trashbag, tie it off and attack a tinfoil hatch cover to it. then he'd let it go. the local air force base would send out interceptors to figure out what these weird radar reflections were..strong when the foil was facing the radar, nothing when edge on. they never found anything and the people at the shipyard had a good laugh over it...

    I get that the military prioritizes reliability over almost everything else (much like the Apollo computer), But the UI on that CAMS system looks seriously frustrating to use, not to mention how slow it was to update readings. Honestly, I'm a little surprised that they only have one backup system each for oxygen and CO2, though I suppose most of the time surfacing acts as your final backup. I do like that they are essentially passive, though.
