A Complete Lack of Motion
If you’ve never been inside a submarine before, you might be surprised to learn that the environment is remarkably tranquil even when there’s a storm going on outside. What exactly is going on over here? This is because submarines typically travel at a depth of at least a few dozen feet below the surface of the water when operating.
The submersible travels at an almost unbroken state of calm, with the exception of a few little jolts here and there to make things exciting. The only sounds that can be heard on board are the buzz of the machinery and the voices of the passengers talking to one another.
