The desire to fly is so strong that it can support an attraction that otherwise would be considered very mediocre - Eddie Sotto taught me ages ago it's a key breason why Dumbo is so popular. It keys into a core shared desire among people regardle of age, race, etc.. People generally don't give two craps about Dumbo as a film or anything, but overlaying it onto the simple spinner gives it the very distinct "flight" nod that something like Triceratops Spin misses out on.
