Factual error: When 007 is briefed inside the submarine, there would be no space available to have spacious offices, wooden desks, and book shelves. Most of the space within a sub would be taken up by the equipment necessary for it to function. In addition, such features (desks, chairs, etc.) would add a considerable amount of weight and be difficult to get inside in the sub in the first place.
