The Invertigo rollercoaster at California's Great America is being temporarily dismantled as part of an ongoing investigation into an incident that left riders stranded last month.
State investigators and Great America personnel are taking the coaster apart in order to determine the cause of a malfunction on August 12, which left 24 riders stranded in mid-air for more than four hours. Urban search and rescue crews from local fire departments were able to safely return all 24 riders to the ground.
It is believed that the ride's lift hill is the focus of the investigation, although official confirmation will not be released until the investigation is concluded. It is unlikely that the ride will re-open until next year.
