John Reilly, president and CEO of Six Flags Entertainment Corporation, said in a statement Friday: "We are reinforcing safety precautions at our parks and taking additional measures, including adding seat belts on Goliath and other coasters with a similar restraint." He did not specify which other rides will get the belts, and Six Flags has not said when the closed coasters are expected to reopen.
All nine of the coasters the company has taken offline were manufactured by Swiss company Bolliger & Mabillard and use similar clamshell restraints, which sit at the top of a vertical bar between each rider's knees. The bar locks a padded restraint into place over the rider's lap and upper legs. A 2001 US patent for the restraint system says it is designed to make riders feel "that he is seated on a flying carpet or that he is at the controls of a kind of flying scooter, while still guaranteeing optimum security."
Goliath remains shut down while state and local officials investigate the Oct. 12 death. Witnesses said they saw Kariem rise up out of his seat and fall headfirst back into the cart before being ejected, and some people who rode Goliath earlier that day said they had concerns about its restraints.
Reilly's statement said Six Flags has enlisted independent engineers and inspectors to review safety procedures for all rides at its theme parks. Other operators have also responded: SeaWorld Orlando in Florida and La Ronde in Montreal each temporarily closed one roller coaster using clamshell restraints. SeaWorld reopened its Mako coaster Tuesday after a week offline. The Associated Press has asked both companies whether they plan seat belts or other safety upgrades.
