The Mindbender is the world's largest indoor triple loop roller coaster. It is located in Galaxyland Amusement Park, a major attraction inside West Edmonton Mall, in Edmonton, Alberta, Canada. Galaxyland is the largest indoor amusement park in the world, and West Edmonton Mall is the largest mall in North America.

[edit] Layout
Mindbender is loosely based on Dreier Looping, a portable coaster that travelled the German funfair circuit, before being sold to a succession of theme parks in Malaysia, Great Britain, and most recently, Mexico. Mindbender is a mirror-image of Dreier Looping, and is slightly taller, with additional helices at the end of the ride. Mindbender features shorter trains, with three cars, whereas Dreier Looping usually ran with five cars, but would occasionally run with seven-car trains at busy funfairs.
The ride's layout features many twisting drops, a double loop, a single loop, and a finishing helix, or horizontal loop. The G-force on the ride is very intense, and many people blackout briefly after the second loop. The ride twists underneath, in between and around its supports. It also goes underneath the "UFO Maze" during the helix.
Often in high season, the last car on one of the trains is reversed, allowing guests to ride the roller coaster without being able to see where they are going.
[edit] Pricing
One ride on the Mindbender is 7 ride tickets, or $10.50 Canadian. It is also covered by the Galaxyland day pass.
[edit] Crash
On the evening of June 14th, 1986, some time after completing the second inverted loop, loose bolts on the wheel assemblies caused the wheels on the final car of the four-car yellow train to become disengaged during a regular run with a full load of riders. This caused the final car to bounce wildly, throwing off passengers and losing speed. The train entered the third and final inverted loop, but did not have the speed to complete the loop. The train stalled at the top, then slid backwards, crashing into a concrete pillar. Three people were killed during the accident and a fourth man was paralyzed.
The MindBender was immediately shut down. An investigation was launched that revealed that there were problems in the translation from German to English of operational and maintenance information from Schwarzkopf, the German coaster manufacturer. In addition, Mindbender crews had ignored a special inspection order from the General Safety Services Division. Cars were checked only by visual inspections, not by taking them out from service. Visual inspections alone would not have been adequate to determine if screws or bolts were loose. It was discovered that one-quarter of all axle bolts on the trains were loose. No safety check had been made through the German TUV organization. The wheel assemblies themselves were also faulted for not having enough wheels in place to prevent the accident. In addition, the restraint systems were also criticised for being inadequate for a ride of this type.
When the Mindbender was reopened seven months later, the train car wheel assemblies were redesigned with additional wheel sets. Additional braking stations were installed before each vertical drop. New full-shoulder restraints were installed to prevent riders from ever falling out. Finally, maintenance checks and scheduled maintenance downtimes were significantly increased. In the twenty years since the accident, the Mindbender has an excellent safety record.
