Green Lantern, formerly known as Chang, is a stand-up roller coaster located at Six Flags Great Adventure in Jackson Township, New Jersey. Green Lantern stands 155 feet (47 m) tall and features a top speed of 63 miles per hour (101 km/h). The 4,155-foot-long (1,266 m) ride features five inversions and a duration of approximately 21⁄2 minutes. The ride was manufactured by Swiss firm Bolliger & Mabillard.
The ride originally operated at Six Flags Kentucky Kingdom in Louisville, Kentucky from 1997 to 2009, where it was known as Chang. Upon opening in 1997, it set world records for this type of coaster in height, drop, speed, length and number of inversions. The introduction of the ride caused Kentucky Kingdom to achieve record attendance levels. After Six Flags abandoned Kentucky Kingdom in 2009, the ride was relocated to Six Flags Great Adventure. The ride debuted in 2011 as Green Lantern, replacing the former Great American Scream Machine roller coaster.
