These loops are very circular as opposed to the loops on most other coasters. This makes for powerful G-forces on the riders.
A few years ago, the original Tornado trains were modified by adding over-the-shoulder restraints. Because the 'horse collars' ratcheted down with the G-forces, riders found them extremely uncomfortable. In early 2001, new trains were delivered, but they had problems using the new cars on the track. Consequently, it never ran in 2001 or 2002 and was dismantled in late 2002. In May 2003, it opened at Six Flags Marine World as Zonga, the Swahili world for "coil" or "loop."
After heavy modifications to two of the loops, the coaster ran for parts of the 2003 and 2004 seasons at Marine World (the park presently called Six Flags Discovery Kingdom), but was removed from the park in 2006.
