The roller coaster initially opened at Six Flags St. Louis on April 4, 1981 and was called Jet Scream. It was closed in 1988 and sent to Six Flags AstroWorld, where it opened the following year as Viper. It was closed and demolished with the park in the fall of 2005.
The ride was painted blue when it originally opened, but it was repainted green when it was relocated.
