The Incredible Hulk is a steel roller coaster located in Islands of Adventure in Orlando, Florida, USA. It is named for the popular comic book superhero character, the Hulk. Voted the #1 roller coaster by Discovery Channel viewers in 1999, the roller coaster is unique because it features a launch lift hill as opposed to conventional chain lifts. This means the train accelerates to 40 mph (64 km/h) in a short time (approximately two seconds) before speeding through several inversions. When the Incredible Hulk opened, it featured the world's tallest cobra roll (110 feet (34 m)). <br />The Incredible Hulk is the only launched roller coaster produced by Bolliger & Mabillard. As a company, it is opposed to launched coasters because of perceived reliability problems, so it subcontracted the launch mechanism to another company. <br />The Incredible Hulk was featured at the beginning of the 1999 film House on Haunted Hill under the pseudonym "Terror Incognita".
