The invention of the wheel may have been a serious point in mankind's development, as it allowed us to more easily move bigger loads. The video on this page however shows that some things like the movement of a submarine into a museum requires lots of wheels, and teamwork of many different people which all have their own specific tasks.
They are all part of the "machine" whose purpose is to move the sub from point A to point B, and together their aligned free will allows them to negotiate the terrain challenges in such a way that the task is accomplished. Of course in such a crucial operation that means check, check and double check!
