Here is a peak at the four passenger contraption that you ride in while on Mission Space at Epcot. You can see the mechanical and hydraulic arms that make this thing rotate forward and backward. On the more intense version of the ride, these "cockpits" also move in a spinning motion on a centrifuge to introduce similar g-forces to those found in real shuttle launches. This is an amazing attraction that everyone who does not suffer from motion sickness should experience at least once. For those who do not feel well while on Mission Space, there are actually "sick sacks" available in each vehicle. There is usually an interesting reaction when unsuspecting guests first notice this. I think the mom in this picture might fall into this category!
