Superman - Ultimate Flight
Here is the world's first "Pretzel Loop" inversion! The loop begins with trains 78 feet above the ground with riders facing down. In this picture, the trains start the loop by moving from the right edge of the picture up towards the center of the frame. The train then pitches down into a half loop. At the bottom of the loop, riders are face up and are subjected to a large, positive g-force pushing their backs firmly into the seats. The train continues with another half loop and ends up again at the top and traveling in the same direction as when it started the maneuver.
