[Buddahaid]

I loved the tour. The intro as stated above doesn't connect well with the rest of the video and mimics the beginning of Das Boot. It's not that the facts are irrelevant, because they are, but they may work better as a conclusion after seeing the interior and restricted living conditions. Perhaps the intro could delve more into this particular subs construction and service life, then move to the tour and conclude with the awful facts of survival.
