Fuji-Q Highland
Using the same type of system as a hydraulic launch, a pneumatic launch uses compressed air to launch the vehicle. The technology was developed by S&amp;S as the "Thrust Air 2000" model. The first coaster of this type was the "Hypersonic XLC", opened at Kings Dominion in Doswell, Virginia, USA in 2001. This coaster closed in 2007. Another incarnation, the Ring Racer was open for only 4 days. Compressed air launches are able to provide more acceleration than traditional pneumatic launches, with Do-Dodonpa at Fuji-Q Highland in Japan holding the acceleration record since it opened as Dodonpa in 2001, launching passengers from 0 to 112 mph (180 km/h) in 1.56 seconds.
