On Road Trip 2010, CNET's Terdiman was given behind-the-scenes access to the North Carolina, the most technologically-advanced nuclear submarine in history. Here, the sub's captain demonstrates how to use a joystick to control the ship's periscope's direction. With that joystick, anyone can rotate the periscope 360 degrees, tilt the view up or down, and zoom in so that details at a mile away are easily discernible.
