Plus Ultra is a fictional secret society featured in the 2015 Disney film Tomorrowland.
Gustave Eiffel met Jules Verne and Thomas Edison at his Tower apartment to start a secret society of optimists. Plus Ultra was founded at the 1889 World's Fair in Paris, France. The organization's purpose is to create, moderate and expand upon new scientific advancements for humanity. Key members of Plus Ultra included Ray Bradbury, Amelia Earhart, Mark Twain, Nikola Tesla, and other key scientific figures. Walt Disney was a member of Plus Ultra.
The Tomorrowland '59 expansion at Disneyland was actually about training future society members for the journey to an alternate-universe that had been found (or developed) by Plus Ultra. The blueprints for the expansion held key technologies that enabled the journey, including Supra Transport.
Key VIPs who were encouraged to join Plus Ultra were given a special VIP audio tour of World's Fair attractions - such as Ford's Magic Skyway, and It's a Small World. For those that couldn't attend the fair, a double-grooved LP was given with the details.
