 Flying Fortress  is the twenty-fifth episode of the Sonic Underground television series and the first of three episodes in the Chaos Emerald Crisis mini-series. It first aired on 31 March 1999 in France and on 1 October 1999 in the United States.
The 2003 season saw Kings Dominion become the final of several of the Paramount Parks to open a Drop Zone: Stunt Tower, now Drop Tower: Scream Zone. The 305-foot-high (93 m) Drop Zone at Kings Dominion was the tallest freefall ride in the world at the time it opened.
Most drop towers require child riders to exceed a minimum height; limits vary widely depending upon the nature of the tower, with a 30-foot (9 m) tower for smaller children from 37 inches (95 cm) tall, and a 115-foot (35 m) tower having a 51-inch (130 cm) restriction.
