The Matterhorn or Flying Bobs, sometimes known by alternate names such as Musik Express or Terminator, is an amusement ride very similar to the Superbob, which consists of a number of cars attached to axles that swing in and out.
They can typically be found at carnivals, where another common name for them is the "Himalaya," but can also exist at amusement parks such as the Flying Bobs at DelGrosso's Amusement Park, KonTiki at Six Flags New England and at Coney Island (Cincinnati) and Matterhorn at Cedar Point and Lake Winnepesaukah.
Cars typically move forward and backward at varying intervals during the ride.
Mack manufactures the Matterhorn, Feria Swing, and Petersburg Schilitenfahrt (Sleigh Ride).
It is currently unknown for what company that manufactured the other version, called "Rip Curl" in Fun Spot in Orlando, Florida.
