Wild Cat (Hersheypark): The Wild Cat (initially The Joy Ride) was a wooden roller coaster located at Hersheypark in Hershey, Pennsylvania, United States.  The roller coaster was constructed in 1923 by the Philadelphia Toboggan Company (PTC).

Temple of the Night Hawk: Temple of the Night Hawk is an enclosed roller coaster located at Phantasialand.  Founded in 1988 after 18 months of construction, the ride was originally called ‘'Space Center'’.  The ride led passengers past models of rockets and emulated asteroids and the darkened hall was dimly lit with thousands of tiny spots of light to resemble stars.  Due to the construction of the neighbouring Wurze Town in 2001, the roller coaster was redeveloped with a fantasy jungle theme and was renamed as the "Temple of the Night Hawk".  The roller coaster is now completely dark.  Until 2006 there were some green moving lights and strobe lights in the first lifthill, still present today, but not operational.  In 2008 the Lights on the coaster trains were turned off or broke down and have never been repaired since then.  Till 2010 there was a green laser projection with the outlines of a flying hawk and until June 2012, there were some red strobe-lights at the final brakerun.  In 2011, the park installed new strobe lights in the first lifthill, which broke down after about two months, and were never repaired since then.  The ride has four trains and one spare train for repairs each with seven cars.  Each car has two rows of seats each holding two people.  During the four-minute ride time the trains are lifted by three lift hill chains, 1.174 metres of track.  The roller coaster is therefore one of the longest indoor roller coasters in the World, slightly beaten by "Mindbender" in Galaxyland Amusement Park, Canada.  The hall in which the track is located is around 120,000m³ in size and rests on 180 concrete pillars which are 12 metres deep in the ground.  In the basement of the hall is the ‘'Hollywood Tour’' darkride.  The total investment for the ride was around 15 million DM.
