Did you know that at the very top of Spaceship Earth is a little secret... secret door, that is. 

That's right... while obviously not accessible to Guests, after taking an elevator about 1/4 of the way up the sphere, then taking stairs adjacent to the ride track to about the 2/3 way-point, there sits a cherry-picker style "elevator" that takes you to the top of the inner shell of the building. 

Inner shell? Yes, Spaceship Earth is actually comprised of two spheres - the inner which houses the attraction, and the outer, which is the shell of the building and holds the Alucobond panels in place. When you get to the top of the elevator, you have to squirm your way through a short, two-foot-high space to reach - the trap door! From there, you can stand and actually exit the sphere at the very top.

Wearing a safety harness, you then attach yourself to the 3 foot tall pole and get a 360 degree view that looks something like this: 

Can you find some other structures on property in the distance? The Tower of Terror for example?

Breathtaking, isn't it?
