American Thunder is an excellent roller coaster in 1904 World's Fair and one of the best attractions at Six Flags St. Louis. The minimum height to ride is 48 inches.
Added in 2008 (and originally named Evel Knievel), this $7 million ride is the park's third wooden roller coaster and was designed and built by Great Coasters International. It is currently the 31st ranked wooden coaster on the planet according to Amusement Today (2014).
American Thunder features an 80' first drop at a 90° left turn angle, and a top speed of 50 MPH. It utilizes two 24-passenger Millennium Flyer trains to traverse a relatively short, tight course (2,700'). Along the way, riders will be treated to sixteen hills and multiple high banked turns at up to 67° angles. Additionally, the track crosses over and under itself fourteen times.
