This rule creates a detailed 3D model of a jetway, also called a jet bridge, the structure that you walk through to get from the terminal on to your plane. You can control the rotation of individual parts of the jetway, the height of the start and end point, and how far it extends from the base. You can add stairs on the side, control the size of the extendable segments, change the side of the wheels it rolls on. It even has some built in presets for the height of different kinds of aircraft.
