Banshee

Banshee is a steel roller coaster located at Kings Island amusement park in Mason, Ohio. Designed and built by Bolliger & Mabillard (B&M), Banshee opened on April 18, 2014. The roller coaster features 4,124 feet (1,257 m) of track making it the longest inverted roller coaster. Banshee is also the first inverted coaster built in the United States since the Patriot debuted at Worlds of Fun in 2006.

History
Banshee was built at the former location of the Son of Beast, a wooden roller coaster plagued with issues and demolished in 2012, and the Thunder Alley go-kart attraction that was removed the same year. In the queue line there is a memorial for the Son of Beast. Following their removal, it was not immediately clear what would replace the attractions. Construction on a new attraction began, however, on April 22, 2013. A trademark for the name "Banshee" was filed on April 24, 2013. Owner Cedar Fair had previously considered using the name for a roller coaster at Cedar Point, but it was later changed to Mantis.

Kings Island began teasing the new attraction on the first day of the 2013 season. Along the perimeter of the former Thunder Alley go-kart track, a fence was set up with a sign that read, "Due to the increasing occurrence of mysterious and bone-chilling screams, it has become necessary to close this section of the park until the cause of this evil phenomenon can be identified." During the course of the summer, several clues about the attraction were set up around the construction site. On June 10, 2013, the park launched their social media campaign by posting a photo showing the construction site with the caption, "Field of Dreams". The campaign continued with five scarecrows around the construction site and several Twitter posts about the future attraction. Then, at the beginning of July 2013, recordings of someone screaming could be heard by park guests near the construction area. Two weeks later, farm owls were placed in nearby trees. On July 31, 2013, Kings Island detailed plans to reveal a new world record-breaking attraction at 10pm on August 8, 2013. Media packages containing a silver comb, artificial hair and a tag were sent out to media outlets to notify them of the upcoming announcement. A limited number of tickets were also made available to the public giving access to a tour of the construction site prior to the revealing and reserved seats at the event, with net proceeds being donated to breast cancer research. Blueprints for the project were leaked to the public on August 1, 2013.

On August 8, 2013, Kings Island officially unveiled Banshee, the world's longest inverted roller coaster. At a cost of US$24 million, the ride is the single biggest investment in Kings Island history. Banshee is the second Bolliger & Mabillard roller coaster at Kings Island following the installation of Diamondback in 2009. It is also the park's 14th roller coaster.

The foundation work for the supports was done by R.E. Middleton, and the rest of the ride's construction was performed by Adena Corporation. The first pieces of track and supports were delivered to the park from Clermont Steel Fabricators on August 16, 2013; the first track piece was erected on August 27, 2013. The lift hill was completed on September 29, 2013, and by the end of October, other elements such as the first drop, dive loop, and vertical loop were installed. A construction update on November 20, 2013, showed that the zero-g-roll was completed. The final piece of track was installed on January 23, 2014, and testing began on March 15, 2014. The ride officially opened to the public on April 18, 2014. On July 10, 2014, less than three months after opening, Kings Island celebrated Banshee's 1 millionth rider, who received a gift package and a commemorative sign.

Ride experience
Banshee stands 167 feet (51 m) tall and features a first drop of 150 feet (46 m). With a length of 4,124 feet (1,257 m), the ride is the world's longest inverted roller coaster. The ride includes seven inversions including two vertical loops, a dive loop, a zero-g roll, a pretzel knot and an inline twist. Riders experience speeds of up to 68 miles per hour (109 km/h) on the 2 minute and 40 second ride.

After departing from the station, the train makes a left turn towards the 167-foot (51 m) chain lift hill. After reaching the top, the sound of a banshee screaming is played as the train drops 150 feet (46 m) into a heavily-banked right turn. After reaching the bottom of the drop, riders enter a dive loop immediately followed by a vertical loop around the lift hill. Continuing down the valley, the train enters the third inversion, a zero-gravity roll, where riders experience the feeling of weightlessness. Next, the train makes an upward left-hand turn into a "pretzel knot" (an element where the train enters a dive loop, followed by an Immelmann loop). Upon exiting the pretzel knot, the train enters a second vertical loop before making a right turn into an inline twist. Following a downward left hand helix, the train makes a final banked right turn into the final brake run leading back to the station. At night, Banshee employs state-of-the-art lighting and fog effects to enhance the riding experience.
