Alton Towers Nemesis Construction

Plans for developing the site began in 1991, when Alton Towers began working on a pipeline roller coaster concept from Arrow Dynamics. The ride, codenamed Secret Weapon 1, was to be themed around a secret military facility.[2] Development of the project was put on hold due to Arrow's financial problems and Mr Wardley's design problems, but was brought back a year later with the codename Secret Weapon 2 this time with the ride being built in a pit, to solve the height restriction problems. However, the project was finally abandoned when John Wardley had the opportunity to ride the prototype, and found it to be slow and energy inefficient.[2]
The park began to look at alternatives and around this time John became aware of the rumours surrounding a new installation by Bolliger & Mabillard at Six Flags. Alton Towers contacted Bolliger & Mabillard who would not give out any specifics about the ride and informed the park to speak to Six Flags. John only did that and after a meeting Six Flags agreed to let Bolliger & Mabillard produce a similar ride for Alton Towers on the understanding that Alton Towers would return the favour.[3] John Wardley worked on this new ride concept which he codenamed SW3, though the theme of a secret weapon evolved into that of organic alien creature.
Nemesis opened in the spring of 1994 to much media fanfare and was one of many major installations at theme parks throughout the United Kingdom.
