Great American Scream Machine

This roller coaster was built in 1989 by Arrow Dynamics.  The company also built two other nearly identical coasters: Shockwave at Six Flags Great America in 1988 and Viper at Six Flags Magic Mountain in 1990.  Viper is the only remaining coaster of the "Three Sisters" of 7-loop coasters built by Arrow, as this coaster was torn down in 2010 and Shockwave was disassembled in 2002 and scrapped in 2004.
