When Walt Disney's idea for a Space Mountain proved to be unworkable in 1960, he approved the legendary attraction the Flying Saucers.
Guests would float on a cushion of air in their own flying saucer. It seemed like it would be an exciting attraction- when it worked. DISNEYLAND's maintenance team hated the attraction and would often "forget" to get it operational again. On days when Walt was in the park, they had to get it running and keep it running all day. Even Walt knew when it was time to throw in the towel. The often closed attraction was finally put out of its misery in 1965.
Amazingly, the company would try the concept again just across the way at Disney California Adventure in Cars Land. That attraction lasted even less time than its predecessor.
