Our fourth Throwback Thursday is Zonga.
Zonga started it’s life as Thriller at Gröna Lund. It was originally purchased by German showman Oscar Bruch. It debuted as the Thriller on May 17th, 1986 at the fairground in Freiburg, Germany. For the next 11 years it mostly traveled the German fair circuit before coming to Six Flags AstroWorld. It started operating in SF Astroworld in 1998, and operated for about 2 years. After that, it stood there (SBNO) non-operative for another 2 years. It then got moved to Six Flags Marine World (Six Flags Discovery Kingdom). When the Thriller was moved from Six Flags Astroworld to Six Flags Marine World, some track modifications were made by Premier Rides. The most significant was increasing the elevation of the first two loops. The affect of this change would be reducing the Thriller’s top speed and lowering the g-forces during the first two loops. Zonga is Swahili for “coil” or “loop”. (source rcdb.com)
Zonga started it’s operations in the Vallejo themepark in April of 2003, and operated for about 2 years, it then stood there SBNO for 2 years, until it got removed to make room for the new Tony Hawk’s Big Spin roller coaster. Zonga was then sent to Isla San Marcos Parque Temático. The ride started operating here in 2008 under the name Tsunami.
