A roller coaster is a type of amusement ride employing a form of elevated railroad track that carries passengers on a train through tight turns, steep slopes, and other elements designed to produce a thrilling experience. Trains consist of open cars connected in a single line, and the rides are often found in theme parks around the world. Roller coasters first appeared in the 17th century, and LaMarcus Adna Thompson obtained one of the first known patents for a roller coaster design in 1885, based on the Switchback Railway which opened a year earlier at Coney Island.
A wooden roller coaster is a type of roller coaster classified by its wooden track, which consists of running rails made of flat steel strips mounted on laminated wood. The support structure is also typically made of wood, but may also be made of steel lattice or truss, which has no bearing on a wooden coaster's classification. The type of wood often selected in the construction of wooden coasters worldwide is southern yellow pine, which grows abundantly in the southern United States, due to its density and adherence to different forms of pressure treatment.
Bolliger & Mabillard, officially Bolliger & Mabillard Consulting Engineers, Inc. and often abbreviated B&M, is a roller coaster design consultancy based in Monthey, Switzerland. The company was founded in 1988 by engineers Walter Bolliger and Claude Mabillard, both of whom had worked for Giovanola.
Millennium Force is a steel roller coaster located at Cedar Point amusement park in Sandusky, Ohio. Manufactured by Intamin, it was the park's fourteenth roller coaster when it opened in 2000, dating back to the opening of Blue Streak in 1964.

It was briefly the tallest and fastest in the world until Steel Dragon 2000 opened later the same year. The ride is also the third-longest roller coaster in North America following The Beast at Kings Island and Fury 325 at Carowinds.

Roller coaster amusement rides have origins back to ice slides constructed in 18th-century Russia. Early technology featured sleds or wheeled carts that were sent down hills of snow reinforced by wooden supports. The technology evolved in the 19th century to feature railroad track using wheeled cars that were securely locked to the track. Newer innovations emerged in the early 20th century with side friction and underfriction technologies to allow for greater speeds and sharper turns. By the mid-to-late 20th century, these elements intensified with the introduction of steel roller coaster designs and the ability to invert riders.
