Basically, Image an S&S Space shot, excepting that there are 3 towers, and you ride in the middle.  There are 3 cables attached to the vehicle, which holds 6riders.  Your secured in by a very loose safety harness, which is simliar to a 5point racing harness like in nascar.  As the ride starts, you get pulled up about 10feet above the ground and then you float there for a few seconds.  After the launch, your individual seats do their thing, and at the top the vehicle is actually above the 3 towers.  You can see a ride review with photos here.
