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.
