Which technique where the roller coaster is allowed to coast through the ride's circuit through the force of gravity is used in Adventure World since 1991?
Turbo Mountain Turbo Mountain was a steel roller coaster at Adventure World in Perth, Western Australia, Australia. The ride was closed and removed in 2009 to make room for a HUSS Shot'N Drop tower named Freefall. The ride was originally located in Luna Park Sydney as a standard Schwarzkopf Jet Star 2 bought second hand. When the ride was moved to "Adventure World" in 1991, the ride's lift hill was modified from a spiral lift hill to a standard chain lift hill due to maintenance.
Star Wars Hyperspace Mountain Star Wars Hyperspace Mountain (formerly known as Space Mountain: Mission 2 and Space Mountain: De la Terre à la Lune) is an indoor/outdoor steel roller coaster in Discoveryland at Disneyland Paris. Originally themed around Jules Verne's classic 1865 novel "From the Earth to the Moon", the attraction first opened on June 1, 1995, three years after the park's debut in an attempt to draw more guests to the financially-unstable European resort. Unlike other Space Mountain attractions at Disney theme parks, the installation at Disneyland Paris has a steampunk-detailed appearance with a Columbiad Cannon and a plate-and-rivet exterior. Under its previous theme, it was the only Space Mountain to feature inversions, a launch, a section of track that exits and re-enters the interior, and a synchronized on-Board audio track.
