The film isminutes long, the length of time a single IMAX reel could hold at the time.The film used aerial shots while flying over Lake Superior and Ouimet Canyon. The film begins with an aerial shot of flying over water, displayed on a small subsection of the screen. After a few seconds, the image expands to the full sixstorey height of the IMAX screen. The aerial shot, along with the large IMAX screen, induced the Kinesthetic effect which meant that viewers would experience the flying sensation due to eye perception overruling the inner ear balance. Viewers were warned to close their eyes if they experienced any discomfort. ........
