[QUOTE="Hornbein, post: 6849161, member: 489043"] Consider a ship with a propeller. A propeller has to be perpendicular to the way you want the ship to move. It has to be perpendicular to the forward direction. In 3D that means that the propeller rotates in the right-up plane. In 4D we have other choices. The ana-right plane is also perpendicular to the forward direction. The propeller could rotate in that plane. That means a horizontal propeller. Such a ship would be able to operate in shallower water, so it seems like the clear choice. (In 4D the dimensions are up, forward, right, and ana. Only up is vertical, all others are horizontal. So the right-ana plane is horizontal.) [/QUOTE]
