Sky Rocket was renovated into which roller coaster, that had the longest drop at the time?
Phantom's Revenge Phantom's Revenge (formerly known as Steel Phantom) is a steel roller coaster at Kennywood. When it opened in 1991, it was the fastest roller coaster and had the longest drop of any roller coaster in the world. The ride was originally manufactured by Arrow Dynamics. After the 2000 season, D.H. Morgan Manufacturing was brought in to renovate the ride, most notably to remove the four inversions. Unlike most roller coasters, the ride's second drop through Thunderbolt's structure is longer than its first drop.
The Smiler The Smiler is a steel roller coaster located at Alton Towers in Staffordshire, United Kingdom. Manufactured by Gerstlauer, it features 14 inversions and holds the world record for most inversions on a roller coaster. The Smiler has suffered a series of setbacks and ride incidents, including a malfunction at a press preview event which delayed the official opening date by two months, and a collision in 2015 which left five riders seriously injured. An investigation by the HSE was initiated, and the ride was closed for the remainder of that season. The ride eventually reopened on 19 March 2016 with revamped safety standards.
