A recent fatality at a Six Flags theme park in Georgia has renewed discussions about the safety of rollercoasters, particularly after a man was thrown from a moving ride and died. The incident, which occurred at Six Flags Over Georgia, involved a rider identified as Hassan Jihad Ibn Kariem, 42, who was ejected from a rollercoaster and found beneath the attraction. Six Flags has since temporarily closed nine rollercoasters across the U.S. and Canada as a precautionary measure.
The ride involved in the fatal incident has not been officially identified, though witness accounts and aerial footage suggest it was the Goliath rollercoaster. According to the Cobb County Police Department, preliminary findings indicate Kariem was ejected from the ride and struck other patrons before falling. While the exact cause of the failure is under investigation, experts point to the potential for a malfunction in the restraint system, which on the Goliath ride consists of a single restraint without secondary safety features.
Doug Perovic, a forensic engineering expert from the University of Toronto, stated that while the event is tragic, it is highly unusual and not indicative of a broader trend in rollercoaster safety. He suggested possible causes for the restraint failure include a manufacturing defect in that specific chair, an inspection error that allowed faulty parts to remain in use, or an action by the rider. Perovic emphasized that design flaws and operator errors are less likely causes for such an isolated incident. "Rollercoasters are safe," Perovic told the Daily Mail. "The systems in place, starting from design and manufacturing, are well made, and the inspection and maintenance are done on a routine, regular basis."
Despite assurances of general safety, the incident follows other concerns raised about Six Flags attractions. Notably, the X2 rollercoaster at Six Flags Magic Mountain was permanently closed in July after a second severe brain injury incident occurred within a week. Reports linked the ride to a string of serious and fatal brain injuries. Studies suggest that while typical rollercoaster forces are comparable to mild football headers or running, the X2's unique "four-dimensional" design, which includes independently rotating seats and rapid inversions, may push human bodies beyond safe limits, leading to rapid brain acceleration and potential injury.
Perovic noted that coaster manufacturers are continually seeking to create faster and higher rides, which can potentially lead to designs that exceed safe G-force limits. He raised the question of whether regulations similar to those for road speeds should be considered for rollercoasters, particularly for extreme designs.
Statistically, rollercoasters remain a relatively safe form of entertainment. In the U.S., approximately 300 million people ride rollercoasters annually, with injuries and fatalities being exceptionally uncommon. A 2013 study found that between 1990 and 2010, an average of 4,423 children visited emergency rooms each year for amusement park ride-related injuries, most commonly to the head and neck. Hospitalization rates for rollercoaster incidents are low, around 1.5% annually, with an average of 4.5 deaths per year. These deaths are often isolated incidents rather than stemming from widespread ride unsafety.
Six Flags Entertainment Corporation, the largest theme park operator in North America, has experienced other incidents. The Doan Law Firm, which tracks amusement park injuries, lists several deaths at Six Flags Over Georgia, though many were due to medical emergencies or other circumstances unrelated to ride malfunction. Over the past 15 years, two deaths related to falling from the company's rollercoasters have resulted in lawsuits and settlements, including incidents in 2011 and 2013 where riders were ejected.
A spokesperson for Six Flags Over Georgia stated that the safety of guests and associates is their highest priority and that the company is committed to rigorous inspection and maintenance procedures that meet or exceed industry standards. They declined to comment on specifics related to the recent incident or other currently closed rides.
