Shockwave was a roller coaster manufactured by Arrow Dynamics at Six Flags Great America in Gurnee, Illinois. Standing 170ft tall and reaching speeds of 65mph, it opened in 1988 as the world's tallest and fastest looping roller coaster with a record-breaking seven inversions: three vertical loops, a boomerang, and two regular corkscrews. Shockwave was closed in 2002 and has been dismantled.
