Fastest Roller Coaster
While it never leaves the park, Kingda Ka roller coaster at Six Flags Great Adventure amusement park in Jackson, New Jersey, is recognized as the world's fastest roller coaster.
Opened in 2005, the Kingda Ka is a hydraulic launch rocket coaster that reaches its top speed of 128 miles per hour in just 3.5 seconds. Its 456-foot-tall tower is also the world's tallest for a coaster. Built by the Swiss ride manufacturer Intamin, the Kingda Ka uses an over-the-shoulder safety restraint system to keep riders in their seats, but there's no guarantee it will keep their lunch in their stomachs.
