Riders were safely evacuated from the California Screamin' rollercoaster at Disney California Adventure when a backpack fell onto the track and forced an emergency stop.
The incident occurred on Friday, July 22, 2011, when the backpack fell from a ride vehicle, according to the Orange County Register. Firefighters were called to evacuate 24 guests from the ride, with no injuries reported.
A Disneyland Resort spokesperson told the newspaper that the ride vehicles on California Screamin' were brought to an automatic stop when the backpack fell onto the track.
California Screamin' opened alongside the rest of Disney California Adventure in 2001, and was manufactured by Intamin. It is the longest rollercoaster in the world to feature an inversion, and features a 108-feet-tall drop and a top speed of 55 miles per hour.
