    Sweetest old man!!!

  37. Thom Thumbe

    My dad was on a sub in WWII. He has related several times thru my lifetime the story how the toilets worked on his boat. I always laughed at the part when he would say how the guys would end up with “freckles” if they didn’t follow the flushing instructions exactly! Plus the cleanup after a mistake was quite an arduous task….not to mention that other sailors were pissed that the head was unusable until you cleaned up your mess.

  59. Cramper TV

    4:27 I think sharp square will win every game

  60. Adam Stanisławek

    sharp square

  61. Crabbycrab

    Very insightful; but gosh it got awkward in the end. "It was all men on the boat, and you're female; and you're a submariner?" While she so properly talks about women, as women; not females. I wish people would stop dehumanizing women, by calling them females, while men are just most often called "men" and not "males" She's super cool though. Most interesting series on the channel!

  62. Daniel Mogens James McMillan

    How come the info in this video isn't classified

  63. Cosmos

    15:06 is when it actually happens.

  64. Colineire

    I love each crew members dedication to their job. They work so hard to make the rest of the crew happy and keep morale high

    When I was in the Navy, I deployed on surface ships, subs, and was aircrew. We went through similar training in Naval Aircrewman Candidate School (NACCS). This training is much more extensive. We pretty much got a lecture and then to the dunker. All I can say is that "anticipation is worse than the event". I got to the point that I just let everyone else exit the dunker and then left. As long as you establish a point of reference, you are good to go. We would, as soon as the dunker went in the water, grab something that allows you to visualize where you are in the helo. Once you do that, the training is easy. However, don't take that to mean that the actual event would be a piece of cake. One can only hope that this training will kick in when the actual event happens. It can save your life.

  69. Daniel Veti

    why so much submarine stuff? do they need people to want to join? It looks horrible on board those things.

    Jesus is God & He loves you Jesus will soon be seen by all men, women, and children up in the clouds. Jesus is returning now! Believe and be saved. Exodus 3:14 (God speaking) And God said unto Moses, I AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you. John 8:58 (Jesus speaking) Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am. John 10:30 (Jesus speaking) I and my Father are one. Isaiah 9:6 For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, *The everlasting Father,* The Prince of Peace. Matthew 1:23 Behold, a virgin shall be with child and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, *God with us.* John 1:1 & 14 1 In the beginning was the Word, and the Word was with God, and the Word was God. 14 And the Word was made flesh (Lord Jesus), and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth. John 8:24 (Jesus speaking) I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins. John 14:9 (Jesus speaking) Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Show us the Father? Hebrews 1:1-3, & 8 (God calls His Son "O God" because Jesus IS God in the flesh) 1 God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, 2 Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds; 3 Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high; 8 But unto the Son he saith, Thy throne, O God, is for ever and ever: a sceptre of righteousness is the sceptre of thy kingdom. 1 John 5:7 For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one. Titus 2:13 Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ Revelation 1:7 Behold, he cometh with clouds *and every eye shall see him,* and they also which pierced him: and all kindreds of the earth shall wail because of him. Even so, Amen. Isaiah 44:6 (God speaking) Thus saith the LORD the King of Israel, and his redeemer the LORD of hosts; I am the first, and I am the last; and beside me there is no God. Revelation 1:8 (Jesus speaking) I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, *the Almighty.* Revelation 22:13 (Jesus speaking) I am Alpha and Omega, the beginning and the end, the first and the last. --- There Are None Righteous --- How To Be Saved Romans 3:10 & 23 10 As it is written, There is none righteous, no, not one 23 For all have sinned, and come short of the glory of God; Luke 5:31-32 (Jesus speaking) 31 And Jesus answering said unto them, They that are whole need not a physician; but they that are sick. 32 I came not to call the righteous, but sinners to repentance. 1 Peter 3:18 (The word “quicken” means “to make alive”) For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh but quickened by the Spirit Romans 10:9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. Acts 4:12 Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved. Ephesians 2:8-9 8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: 9 Not of works, lest any man should boast.
