With the ride having been listed for sale for over a year, Kings Dominion officials have confirmed that HyperSonic XLC will be dismantled prior to the 2008 season.HyperSonic, built by S&S Power in 2001, was the first ever roller coaster to utilize a compressed air launching system. This launch system catapulted the ride's 8-passenger trains from zero to 80 miles per hour in 1.8 seconds and up a vertical climb, cresting 165 feet in the air and then plunging down a 133-foot drop, which starts out vertical at 90 degrees. Following the drop, the ride maneuvered through two fast curves and over a hill into the brake run.The ride, which remains available for sale through ride broker Ital International LLC, will start coming down in the next few weeks. The coaster was originally built at a cost of 15 million dollars.The ride had received modifications in 2002 in order to increase its reliability. The most visible change was the new, larger seats installed on the trains.
