On July 22, 1999, Paramounts Great America announced they would open a roller coaster made by Vekoma named Stealth. CGA called it the first ever Flying Coaster. The construction of the ride forced the reconstruction of the lower half of the parks Arrow Dynamics log flume ride (loggers Run). Stealth opened on April 1st, 2000, and was painted gray red and white.
It closed just over 3 years later on August 21st, 2003 and was replaced by California’s Great America’s in-park water park known as Boomerang Bay. The ride moved to Carowinds theme park in Charlotte, North Carolina and was renamed and repainted black with green to become Borg Assimilator.
In 2008 BORG Assimilator got repainted yellow and blue, and was given the name Nighthawk. This was done to make the park look more vibrant, since the darker colors of BA seemed to make the are look rather sad. It is one of the 3 Vekoma Flying Dutchman coasters in the world.
The ride featured a horseshoe, as well as 5 inversions: a vertical loop, a double corkscrew, 2 lie to flys, and 2 fly to lies. Each fly/lie inversion counts as only half of an inversion. The ride is 115 ft. high and 2766 ft. long while hitting speeds up to 51 mph and pulling a max. 4.3 Gs.
