In the spring of 1997, Six Flags Kentucky Kingdom [then known simply as 'Kentucky Kingdom'] did something unprecedented for this small park by turning guests head-over-heels 5 times while standing up at speeds in excess of 60 miles per hour with the park's first major record-breaking thrill ride. Contracting popular designers Bolliger and Mabillard, the park installed the world's tallest, fastest and longest steel stand-up coaster and named it Chang. To maintain costs within a reasonable boundary for the now-growing theme park, Kentucky Kingdom chose a design similar to one already used for the Mantis at Cedar Point in Sandusky, Ohio, just taller, faster, longer and with one additional inversion to flip riders head-over-heels.

Lifting riders up nearly a full story higher than Mantis, the yellow, blue and red-colored train swoops around a small curve and slowly heads for the drop, beginning to pick up speed and exceed the Ohio coaster's at 63 miles per hour. Next, passengers soar around a huge 130-foot tall vertical loop and then snake through a diving loop. A quick helix follows next followed directly by a rare Inclined Loop - a vertical inversion tilted at 50 degrees. But the real mayhem of Chang doesn't unfold until after a quick upward curve and set of block brakes. Riders enter a spaghetti bowl of twists, banked turns, and two more inversions - a pair of Flat Spins or Corkscrew Loops. After lateral airtime and wild curves on a final run to the station, the brake run finally meets up with the train and the ride concludes.

To this day, Chang stands out as the signature attraction and the prime reason for many to visit Six Flags Kentucky Kingdom.
