    Hey ! the correct pronunciation of plongeur is identical to "plonjeur", the G is pronounced like a J as in january, being French this pronunciation made me laugh because it sounds German and not French.

    This was crazy interesting, and incredible that Naval leadership would approve this type of educational material being filmed, produced, and released for public consumption. Very cool! I'm wondering if you've considered videos similar to this one, but in analysis of different military aircraft? As a military and aviation nerd, I feel like a SmarterEveryDay video on military aircraft would be something amazing!

    Immensely interesting! I am glued to the screen. The questions you ask are so intelligent and help you to get more information while you are talking with the guy explaining things. Second takeaway: these nuclear boats are marvels of engineering, containing so many different technologies to make the boat operational. Thirdly the process of extracting CO2 from the air is just as exciting as generating oxygen.

    This is what makes this channel so special. Destin is not afraid to ask the questions and get hands in with everything he possibly can. Where most hosts would just sit back and let the interviewee lead the entire conversation, Destin will ask the questions that most would be too timid to. And Tory has to be one of the most intelligent and engaged CEO's of a multi-billion dollar company I've ever seen. He is an absolute legend and his employees and clients are very lucky to have someone like him. He is going to be impossible to ever replace.

    Hey, I know this video is about the moon, but I have had this question on my mind for a while now, and the recent Mars landing has brought it back again (and I can't think of anyone else to ask) so here goes... This is regarding the 7 minutes of terror: Do you think that it is possible for NASA to build signal amplifiers that would be strategically placed between Mars and Earth, and these would boost the signal enough to reduce the delay in communication time? Or is this still too far in the future? I'm thinking 2 or 3 satellites spaced evenly across the distance whose purpose is to catch and slingshot the signals back and forth... Thank you for your response (provided you get this message, or for anyone else who may have a theory/answer).
