SkyScreamer is a vertigo-inducing variation on the classic "Chair-O-Plane" attraction, and sees riders swinging in a 98-foot circle around a central tower. Reaching a top of speed of over 43 miles per hour, they are able to take in panoramic views of the park and its surroundings. Guests are seated in 2-seater swings, each of which provides a "front row seat". Sitting at the top of the ride is a globe that can be seen from several miles away.
At 236-feet-tall, the new ride is the tallest attraction at Six Flags St Louis and opened in time for the park's 40th anniversary season in 2011.
