Viper was a steel roller coaster which operated at two Six Flags parks. These parks were Six Flags AstroWorld and Six Flags St. Louis.


The roller coaster initially opened at Six Flags St. Louis on April 4, 1981 and was called Jet Scream.[1] It was closed in 1988 and sent to Six Flags AstroWorld, where it opened the following year as Viper.[2] It was closed and demolished with the park in the fall of 2005.[3]



The ride featured a single vertical loop and a tunnel.


2 trains with 7 cars per train. In each car, riders are arranged 2 across in 2 rows, for a total of 28 riders per train.
