Plans to build Kingda Ka were announced on September 10, 2003, at an event held for roller coaster enthusiasts and the media. The event revealed the park's goal to build "the tallest and fastest roller coaster on earth", reaching 456 feet (139 m) and accelerating up to 128 miles per hour (206 km/h) in 3. 5 seconds. On January 13, 2005, Kingda Ka's tower construction was completed, and on May 21, 2005, the ride opened to the public. Kingda Ka became the "tallest" and "fastest" roller coaster in the world, taking both world records from Top Thrill Dragster at Cedar Point. It lost the title of world's fastest when Formula Rossa at Ferrari World opened in November 2010. Intamin designed both Kingda Ka and Top Thrill Dragster, and the two share a similar design and layout that differs primarily by the theme and the additional hill featured on Kingda Ka. Both rides were built by Stakotra and installed by Martin & Vleminckx.
