Hydraulic launch technology faces competition from S&S Power, a leading manufacturer in vertical amusement rides, who in recent years created a new breed of coasters with pneumatic launch power. Their coaster model, the Thrust Air 2000, was first built in Kings Dominion in Doswell, Virginia, USA, under the name Hypersonic XLC. The coaster has been clocked to launch from the rest at station to 80 mph (128 km/h) in 1.8 seconds. The coaster proceeds to ascend a tower at 90 degrees and descends vertically. Another compressed air–launched coaster, built in Fuji-Q Highland, is Dodonpa. This coaster is capable of launching passengers from 0 to 106.9 mph (171 km/h) in 1.8 seconds.
