How Hyperspace Mountain Fits Into the Star Wars Story

There has always been a cosmic connection between Star Wars and Space Mountain. Star Wars opened on May 25, 1977. Space Mountain at Disneyland opened two days later. Many Southern Californians would see the movie, which even in its early days was proving to be something of a phenomenon, and head straight to Disneyland, where they'd get in line to experience the sensation of space travel for themselves.
