...128 mph in 3.5 seconds... (8 pics + video)
Kingda Ka is a roller coaster located at Six Flags Great Adventure in Jackson Township, New Jersey, USA. At its opening on May 21, 2005, it became the tallest and fastest roller coaster in the world, claiming the title from Top Thrill Dragster at Cedar Point. The train is launched by a hydraulic launch mechanism to 128 miles per hour (206 km/h) in 3.5 seconds. At the end of the launch track, the train climbs the main top hat tower reaching a height of 456 feet (139.5 m). Due to aviation safety concerns, the tower is equipped with three dual strobes: 2 mid-way up, and one on the top.
