In California, a woman was injured on a similar ride in 2003 when a safety system failed. In that incident, the net for an Adrenaline Drop ride at the Orange County Fair stretched to the ground, allowing the 30-year-old woman to hit the safety padding underneath. She was hospitalized but released the next day, the Los Angeles Times reported.

Terminal Velocity, Montic’s SCAD Diving and Adrenaline Drop are all described on company websites as the “only” ride in the world that allows people to experience unattached, controlled free fall. And each says a system of air tubes and break suspensions around a double net are used to softly stop the fall.

The Orange County Fair no longer uses the ride and hasn’t since 2003, a spokeswoman said. The company that owns Adrenaline Drop did not return phone calls seeking comment.

Anderson could not be reached for comment Saturday. The amusement park’s website states the park is temporarily closed and refers questions to the Lake Delton Police Department. Most of the content on the Extreme World website had been taken down Saturday evening.
