History
TOGO developed the first Pipeline coaster and the first recorded Ultratwister coaster built was in 1985 at LaQua amusement park in Tokyo, Japan called Ultra Twister. The ride became somewhat popular in Japanese parks, and one year after the first was built, Six Flags purchased one of these coasters for their Six Flags Great Adventure theme park, where it resided until 1990 when it was moved to Six Flags Astroworld until the park closed in 2005. This coaster would remain the only pipeline coaster in America. The American Ultratwister still exists, however it awaits possible future assembly at Six Flags America.
TOGO's model would be the only somewhat successful design. Six of these were made and were successful in small parks due to its small footprint. The ride inverts riders three times through three Heartline Roll elements and utilizes a special near-vertical lift hill. The lift hill would be prone to down time for maintenance and the Ultra Twister owned by Six Flags had its lift hill modified by Premier Rides to a less steep angle when it was moved to Six Flags Astroworld.
Throughout the early 1990s, Arrow Dynamics attempted to develop a pipeline roller coaster. Only one of these was built as a prototype at Arrow's facility in Utah. Plans for the coaster were scrapped altogether due to roughness and other factors. However, one was partially built at Alton Towers in the United Kingdom. In the early 1990s, John Wardley twice attempted to build one of these at the park. The second attempt was partially built, but then scrapped for the coaster Nemesis. The coaster was not completely finished due to Arrow's finance problems.
In the mid 1990s, Intamin built a spiral roller coaster in South Korea. Not much is known about the design, but only one of these coasters were built. The only Spiral Coaster ever built is located in Kuwait, but it has been closed for several years and is considered unlikely to operate again.

Famous quotes containing the word history:
“Anyone who is practically acquainted with scientific work is aware that those who refuse to go beyond fact rarely get as far as fact; and anyone who has studied the history of science knows that almost every great step therein has been made by the “anticipation of Nature.””
—Thomas Henry Huxley (1825–95)
“You that would judge me do not judge alone
This book or that, come to this hallowed place
Where my friends’ portraits hang and look thereon;
Ireland’s history in their lineaments trace;
Think where man’s glory most begins and ends
And say my glory was I had such friends.”
—William Butler Yeats (1865–1939)
“When the landscape buckles and jerks around, when a dust column of debris rises from the collapse of a block of buildings on bodies that could have been your own, when the staves of history fall awry and the barrel of time bursts apart, some turn to prayer, some to poetry: words in the memory, a stained book carried close to the body, the notebook scribbled by hand—a center of gravity.”
—Adrienne Rich (b. 1929)
