American Thunder is a wooden roller coaster located in the 1904 World's Fair section of Six Flags St. Louis in Eureka, Missouri.

Opened on June 20, 2008, the coaster was originally named after and themed to the famous motorcycle daredevil Evel Knievel.

[2] As a result of the St. Louis Cardinals losing to the Chicago Cubs in the 2015 National League Division Series, Six Flags St. Louis lost a friendly wager with Six Flags Great America, resulting in the temporary name change of the roller coaster to Cubs Thunder.

[3] This $7 million GCI wooden roller coaster, which is identical to the Thunderbird at PowerPark, features an 80-foot (24 m) drop with a top speed of 48 mph (77 km/h), going through a course of 2,700 feet (820 m) of track.

[4] This ride features 16 hills and multiple high banked turns at up to 67° angles.
