The ride is 36.9 metres tall and has a drop at an angle of 85 degrees. The car reaches a maximum speed of 80 km/h. It has a single car which seats 24 riders, held in by over-the-shoulder harnesses.
On 15 April 2004, 16-year-old Hayley Williams died after falling from the attraction. A 10-year old boy was hit by Williams as she fell and was subsequently hospitalised with head injuries. Hydro remained closed for the rest of the 2004 season while an investigation was carried out. Prior to reopening, the original lap-bars and seatbelts were replaced with over-the-shoulder harnesses. Another Intamin Shoot-the-Chutes ride, Perilous Plunge at Knott's Berry Farm in California had already had its restraints modified after a woman fell to her death from the attraction in September 2001.
An investigation into the incident found that Williams was not properly restrained. CCTV footage also revealed that restraints were regularly not checked by the ride operators. In December 2008, the park was fined £250,000 and forced to pay an additional £80,000 in costs.
