[PAR] [TLE] Rotor (ride) [SEP] The Rotor is an amusement park ride, designed by German engineer Ernst Hoffmeister in the late 1940s.  The ride was first demonstrated at Oktoberfest 1949, and was exhibited at fairs and events throughout Europe during the 1950s and 1960s.  The ride still appears in numerous amusement parks, although travelling variants have been surpassed by the Gravitron. [PAR] [TLE] Gravitron [SEP] The Gravitron (also known as the Starship, Starship 2000, Starship 3000, Starship 4000, Starship Area 51, Starship Gravitron, Starship Exodus, Alien Abduction, Alien Invasion, Twister, Devil's Hole, Area 51, and Enterprise) is an amusement ride, most commonly found as a portable ride at fairs and carnivals.  The Gravitron first appeared at Morey's Piers in 1983 and quickly became a fixture at amusement parks in many countries.  It is a modification of an earlier ride called the Rotor.  The ride was originally designed and manufactured by Wisdom Industries, though several examples of the Gravitron were produced under license by ARM in the UK and Ferrari in Australia.
