Forget the rollercoaster, look for the black thing sticking up on the left side of the photo. That is the track for a ride that starts with you sliding over the edge of the tower. Once there it then drops you so you are pointing down at more than 45 degrees.
There is also a new ride that will suspend you over the side while it spins you around at 45 MPH or something. Talk about having confidence in the engineering team.

PS - I was just there last week so that's why I recognised it so quickly.
