Geddes' "future" was synonymous with technological progress in its simulated low-flying airplane journey through the exhibit. The aerial journey was simulated by an 18-minute ride on a conveyor system, carrying 552 seated spectators at a time, covering a ⅓-mile winding path through the model, along with light, sound, and color effects. The ride moved at a rate of approximately per minute or , allowing spectators to look down through a continuous curved pane of glass towards the model. The virtue of this elevated position allowed spectators to see multiple scales simultaneously, viewing city blocks in proportion to a highway system, as well as artificially controlled trees in glass domes. This scale was modeled off 408 topographical sections based on aerial photographs of different regions of the U.S. provided by Fairchild Aircraft Ltd..
