i can clearly see the sub marine on the picture !!! look in the harbour (shown on the left image) there is a subways and right before the entrance there is a marine ... not to mention he has the sub of the day in his hand and walks away which looks a bit like drunken to me and "sunken" could just be a bad typo... maybe too few pixels for everyone to see it, but its there !!!

don't fall for propaganda, fall for turboprops or ghandi, for submarines or cranes, maybe for the shadows (of babylon5) if you insist but plz not for propaganda !
