Laser Loop was Kennywood's first looping roller coaster, it was built in 1980 by the German Anton Schwarzkopf - the same man who would eventually build Kennywood's Raging Rapids in the winter of 1984. It was built on the site of the old Skooter building above the park entrance, but was removed after the 1990 season to make room for the Steel Phantom. As the ride grew older, costs of maintenance began to outweigh the benefits of the Laser Loop. During its last season at Kennywood, the Laser Loop was closed frequently due to problems with the flywheel & clutch system used to propel the ride. It would eventually be replaced by the Steel Phantom in 1991, which maintained a few of the Laser Loop's features like a vertical loop and fast re-entry to the station.
