Montezooma's Revenge is a steel shuttle roller coaster at Knott's Berry Farm in Buena Park, California. It opened on May 21, 1978.^[1] Designed by Anton Schwarzkopf,^[1] it is one of eight flywheel-launched units manufactured for theme parks around the world.^[2] It is the last ride of its kind still operating in the United States, and remains one of the most popular attractions at Knott's Berry Farm.^{[citation needed]}

Like many other Anton Schwarzkopf designed looping coasters, Montezooma's Revenge uses lap bars to hold riders in the seats instead of conventional over-the-shoulder restraints found on most other steel looping roller coasters.^[1] Following Cedar Fair LP's 1997 takeover of Knott's Berry Farm,^[3] fabric seat belts were added as a secondary restraint system.^[1]

History

Montezooma's Revenge was named after the bluegrass group, Montezuma's Revenge, a musical act that performed regularly in the wagon camp at Knott's Berry Farm.^{[citation needed]}

Based on the launch mechanism for aircraft carriers, the flywheel-launched shuttle loop is a successor of the drop-tower launch shuttle, and predates modern LIM and hydraulic launch systems by over 15 years. The drop tower models had a large silo with a weight inside connected to a similar launch system. The weight would drop, thus pulling the cable and bob, launching the train. Drawbacks included no adjustments for inclement weather. Also, the drop-tower launch was nowhere as intense as the flywheel launch, taking almost two seconds longer to reach the same speed. The drop-tower launch system is no longer used.

The nearby Jaguar! roller coaster passes directly through the center of Montezooma's loop.^[4] Jaguar! was opened in 1995.^[5]

In 2002,^{[citation needed]} Montezooma's Revenge was repainted with teal track and yellow supports, where previously, it had yellow track and yellow supports.^[1]

In 2008, Knott's opened Pony Express, a small "out and back" steel roller coaster^[6] with a flywheel launch system much like Montezooma's Revenge.^{[citation needed]}

Launch mechanism and safety features

The ride uses a flywheel mechanism to accelerate the train to 55 miles per hour (89 km/h) in 4.5 seconds. The train goes through a loop, then ascends a tower and reverses direction. It passes through the station in reverse and ascends another tower behind the station.

The 7.6 tonnes (7.5 long tons; 8.4 short tons) flywheel, located outside the station and adjacent to the loop, is attached to a clutch and cable system, which in turn connects to a small four-wheeled catch car known as a "bob". On the front of the bob is a launch pin that seats in a socket in the back of the train. This is one of the primary safety features: the bob, through the restraint mechanisms, completes an electrical circuit. If any restraint is not working, the circuit is not made and it is impossible to launch the train until the situation is addressed. Once the bob is seated and the circuit made, the operators receive the ready light.^{[citation needed]}

Two operators are required to launch the train. After verifying that all passengers have secured their restraints and checking the exit stairs, one operator ascends a podium at the right front of the train. The other operator stands on a platform at the left rear. After verifying that the launch area is clear of personnel, the front operator gives a thumbs-up signal and says, "Clear; dispatch." Both operators must then press a button on their respective consoles simultaneously to launch.^{[citation needed]}

At launch, the clutch system engages the cable to the spinning flywheel, pulling the bob and train rapidly forwards. During the launch sequence, enough kinetic energy is removed from the flywheel to reduce its speed from approximately 1044 rpm to 872 rpm.^[2] The train negotiates a 46-foot (14 m) diameter vertical loop before ascending the 148-foot (45 m) front tower, then descends backwards, going through the loop a second time, running at full speed backwards through the station, and ascending the 105-foot (32 m) rear tower. It is at this point where the best "airtime" on the ride is experienced.^{[citation needed]} The train then returns to its starting position after being slowed by 66 sets of brakes, 33 in the station and 33 to the rear of the station.^[1] Less than a second after the ride stops, the restraints release.^{[citation needed]}

During night time operation, the station lights dim at the instant of launch.^{[citation needed]}

Incidents

Justine Dedele Bolia, a 20-year-old woman, died on September 1, 2001, one day after riding Montezooma's Revenge. Bolia suffered a ruptured middle cerebral artery, and an autopsy revealed a pre-existing condition. The ride was closed for several days while an investigation was conducted. Though state investigators concluded that the ride did not contribute to her death, a wrongful death lawsuit was later filed by her family in 2002.^[7] The lawsuit was dismissed in 2006.^[8]
