full_context: Document 1: Flying Scooters: Flying Scooters, also known simply as "Flyers", is an amusement ride consisting of a center post with ride vehicles suspended from arms attached to the center post. The ride dates back to the 1930s and 1940s when Bisch-Rocco manufactured the ride. In the early 2000s, Larson International revived the concept and is the sole manufacturer of these rides.
Document 2: Zierer: Zierer Karussell- und Spezialmaschinenbau GmbH & Co. KG (Short name: Zierer) is a German company located close to Deggendorf. Zierer manufactures Tivoli and Force line of roller coasters, as well as panoramic wheels, wave swingers, flying carpets, "Hexentanz" and "Kontiki" rides. The company also has partnered with Schwarzkopf to build "Lisebergbanan" at Liseberg and "Knightmare" at Camelot Theme Park.
Document 3: Holiday Park, Germany: Holiday Park is an amusement park in Haßloch, Germany. It is one of Germany's most popular theme parks (receiving about a million visitors per year) and is part park and part woodland. Its Free Fall Tower was the first amusement ride of its kind in Europe. The Park also offers several roller coasters, including Expedition GeForce, water rides, and live shows.
Document 4: Olympia Looping: Olympia Looping, also known as Munich Looping, is a portable steel roller coaster designed by Anton Schwarzkopf and built by BHS. It is the largest portable roller coaster in the world, and the only one with five inversions. It appears at many carnivals in Germany, most notably Oktoberfest, where it made its debut in 1989. It is named for its five vertical loops, which resemble the Olympic rings. Although they are clothoid-shaped, their shape is closer to circular than the ones on most other roller coasters, so they exert unusually high "g"-forces on the passengers (up to 5.2 g). The entire structure weighs 900 tons and requires a space 85 m wide by 36 m deep. The ride usually runs with five cars per train, though at events such as Oktoberfest and Winter Wonderland in Hyde Park, London, it runs with seven to increase throughput in busy periods.
Document 5: Swing Around: The HUSS Swing Around is an amusement park ride formerly manufactured by HUSS. It was HUSS Maschinenfabrik's first ride model, debuted in 1969. It is not manufactured by the company anymore, but there are a handful of known units left around the world. The ride rotates in a circle, and the arms swing out, and then come in. They keep on doing this during the ride, in bigger and bigger increments until the very end, where they all swing out, using pneumatic pressure. Most parks require riders to be 42 inches tall to ride; anyone under 48 inches tall must ride with an adult.
Document 6: Van Helsing's Factory: Van Helsing's Factory is a steel enclosed roller coaster at the Movie Park Germany amusement park in Bottrop, Germany. The Gerstlauer dark ride opened in June 2011 as a replacement for the defunct "Gremlins Invasion" ride.
Document 7: Bayern Kurve: The Bayern Kurve is an amusement ride made in both a portable and park model that debuted in 1965 and was invented by German engineer Anton Schwarzkopf. During the ride, riders sit in one of the sixteen bobsled-themed cars that travel at a high-speed around a circular single-hilled track. Riders start in an upright position and as the cars pick up speed, they tilt inward toward the center of the ride. This ride is also known for its loud horn which is similar to that of a diesel train engine that blasts its loud roar when the ride reaches maximum speed. Also akin to a train, the seamed track creates the same rail "click-clack" railway sound, particularly at the lower section of track in the front. Additionally, the ride has a distinct whine that increases with speed due to its tire/blade drive.
Document 8: Rainbow (ride): Rainbow is the name of the amusement park ride created by HUSS Maschinenfabrik of Bremen, Germany which is now HUSS Park Attractions of Budapest, Hungary. The Rainbow was manufactured from 1983-2000 and is often confused with its cousins Ali Baba (ride) and 1001 Nachts but there are major differences between the ride designs. The HUSS Rainbow has developed a vast fan base due to its large stature, smooth ride and bright lights.
Document 9: Gravitron: The Gravitron (also known as the Starship, Starship 2000, Starship 3000, Starship 4000, Starship Area 51, Starship Gravitron, Starship Exodus, Alien Abduction, Alien Invasion, Twister, Devil's Hole, Area 51, and Enterprise) is an amusement ride, most commonly found as a portable ride at fairs and carnivals. The Gravitron first appeared at Morey's Piers in 1983 and quickly became a fixture at amusement parks in many countries. It is a modification of an earlier ride called the Rotor. The ride was originally designed and manufactured by Wisdom Industries, though several examples of the Gravitron were produced under license by ARM in the UK and Ferrari in Australia.
Document 10: Rotor (ride): The Rotor is an amusement park ride, designed by German engineer Ernst Hoffmeister in the late 1940s. The ride was first demonstrated at Oktoberfest 1949, and was exhibited at fairs and events throughout Europe during the 1950s and 1960s. The ride still appears in numerous amusement parks, although travelling variants have been surpassed by the Gravitron.
Document 11: UFO (ride): The UFO is an amusement park ride designed by HUSS Maschinenfabrik in 1978, based on the company's Enterprise and Skylab amusement rides. Numerous carnivals feature this ride which is known as Alpha One Peeters and Vertical Limits.
Document 12: Astro Orbiter: The Astro Orbiter is a rocket-spinner attraction featured at all six Disneyland-style parks at Walt Disney Resorts around the world. Although each ride may have a different name, all share the same premise of vehicles traveling through space by spinning around a central monument. As each form of the attraction appeared, new designs and locations have been implemented to fit with changing schemes of several Tomorrowlands.
Document 13: Roller coaster: A roller coaster is a type of amusement ride that employs a form of elevated railroad track designed with tight turns, steep slopes, and sometimes inversions. People ride along the track in open cars, and the rides are often found in amusement parks and theme parks around the world. LaMarcus Adna Thompson obtained one of the first known patents for a roller coaster design in 1885, related to the Switchback Railway that opened a year earlier at Coney Island.<ref>
Document 14: Submission (Alton Towers): Submission was a Chance Rides Double Swinging Inverter located in the X-Sector area and was built in 2001. From 2005, the ride only operated one of its arms to save electricity and the ride's cycles were shortened. The slogan used in advertisement was 'Hang in there'. Following the area's theme, the ride was painted blue and was covered in a shiny metal, most likely steel. Each of its two arms had a counterweight in the shape of two metal spikes, which would sweep near to the ground like a scythe. The sequence was always the same, different to some other weight based rides that have numerous sequences, this was also probably to be more energy efficient. The Ride type itself is a rare flat-ride and not seen at a lot of themeparks, Submission did not have the best of reviews at Alton Towers mainly due to it having the same sequence (unlike others such as Ripsaw), the restraints were very similar to those on a Huss Top Spinner making it fairly uncomfortable to ride when inverted, breakdowns occasionally happened and as a result, queues were very short. In 2013 it was later revealed that Submission would be closed after the end of the 2013 season by which there is a vacant grass area where it once stood next to the break-block section on Oblivion. The grass area is often referred to as the 'Submission memorial ground' by thrill-seekers which has become a popular sitting area in the park section.
Document 15: Enterprise (ride): The Enterprise is an amusement ride, manufactured primarily by HUSS Park Attractions and Anton Schwarzkopf beginning in 1972. The HUSS ride was an adaptation and improvement of a design produced earlier that year by Schwarzkopf, with an increased passenger capacity. Despite not owning the original incarnation of the ride, HUSS was issued the patent.
