"One goal in designing the ride system was to deliver an experience similar to what it would feel like to be with Tarzan or a similar character swinging between trees of a jungle on a vine or with Spider-Man or a similar character swinging on webs between buildings as you move down streets of a city. [The ride is] intended to have swinging sensation provided while also having forward travel along a ride path in a direction of travel and for the swinging sensation to feel thrilling and fun."
