Great American Scream Machine was a steel roller coaster located at Six Flags Great Adventure in Jackson Township, New Jersey. The 173 ft ride opened in 1989 as the tallest and fastest looping roller coaster in the world, reaching a maximum speed of 68 mph. It was designed by Ron Toomer and manufactured by Arrow Dynamics, which built two other coasters with similar layouts – Shockwave at Six Flags Great America and Viper at Six Flags Magic Mountain. Great American Scream Machine featured seven inversions including a batwing and double corkscrew. Records set by the ride were succeeded by Viper the following year in 1990. It operated until July 2010 and was replaced by a stand-up roller coaster, Green Lantern, in 2011. Green Lantern closed on November 10, 2024, and will be replaced by a "multi-record-breaking launch coaster".
History
The coaster was originally going to be named Ninja, but there were problems with the crowds drawn to the Ninja coasters in other parks. Instead, the name Great American Scream Machine was selected.[2] Great American Scream Machine was announced in September 1988.
