Just found this video on YouTube and it has the workings for Star Tours pretty cool.
Watch from 1:45 to see it in action.

Thanks for posting, it's quite eye opening to see quite how much it moves and also how high off the ground it is. It's an amazing testament to the engineering that it doesn't break down more.
