I'm pretty sure you all know of Star Tours right? If you don't, you don't belong here! But, I'm sure you don't know what it replaced.

(Head scratching and guessing)

If you said 'Adventure Thru Inner Space', your absolutely right! This classic darkride sends you through the key piece of the attraction, "The Mighty Microscope", where you and your OmniMover Vehicle, dubbed Atommobiles, shrink to the size smaller than an atom and get sent in through a snowflake. It ended with the infamous Scientist Eye looking down through the Mighty Microscope down on you. It was origionally sponsered by Monsanto, but they quit their sponsership, and a few years later, ATIS was closed to make way for Star Tours.
One site that I know of, themightymicroscope.com, has done many things to preserve the memories of the attraction. Among things are an ATIS computer theme, many pictures, and even a CGI of the attraction.
For those of you who remember the attraction, we all miss it. If your a fan, you'll miss it more. If you don't care, just get out of this entry and go through other things.
