Adventure Thru Inner Space
The ride that replaced Star Tours in Disneyland’s Tomorrowland was called Adventure Thru Inner Space before Star Tours came. It first opened as an Omnimover attraction on August 5, 1967, simulating humans shrinking to the size of an atom. A Monsanto Mighty Microscope with a glass tube was located on one side of the ride. As they proceeded over the course, spectators could see the other riders diminish.
The Omnivmover technology, which can now be used in such like the Haunted Mansion and Buzz Lightyear’s Astro Blasters, was initially used in this Disney attraction. In 1985, the attraction was decommissioned to make way for Star Tours.
The Twilight Zone Tower of Terror
Technically, this ride still exists, but it has undergone significant changes. The Twilight Zone Tower of Terror debuted at Disney World’s Hollywood Studios on July 22, 1994, and has since been added to a few other Disney parks. Guests would board a haunted Hollywood hotel elevator and instantly drop hundreds of feet.
Following Disney’s acquisition of Marvel in 2017, the ride received a complete makeover. Guardians of the Galaxy – Mission: Breakout! is the new title. The updated version retains the same technology as the original, but adds characters from the Marvel film.
