 On May 8, 2007, four days before Maverick was scheduled to debut, park general manager John Hildebrant announced that the ride would be delayed until early June because three track sections after the second launch needed to be replaced.These sections made up the heartline roll element and put excessive stress on the trains, which also might have caused discomfort to passengers due to high g-forces.On May 17, 2007, the heartline roll was removed and was replaced with an s-curve.
