Cedar Fair has moved to temporarily close all of the WindSeeker swinging tower rides at its theme parks following two separate incidents at Knott's Berry Farm.
The LA Times reports that the WindSeeker attractions at Kings Island, Cedar Point, Canada's Wonderland, Carowinds and Kings Dominion have been alll been closed as a precautionary measure. This comes after several incidents which have seen guests stranded at the top of the towers, including one on September 19 which left 20 riders stuck in mid-air on Knott's Berry Farm's version.
An internal review is currently being undertaken into the causes of the breakdowns, with Cedar Fair stating that none of the rides will reopen until this has been completed. The WindSeeker attractions were the first swinging tower rides built by Dutch firm Mondial, although rival firm Funtime has installed similar rides under the SkyScreamer name at rival Six Flags parks across the US.
WindSeekers see guests swinging in circles around a central tower in a vertigo-inducing variation on the classic "Chair-O-Plane" attraction. Riders reach speeds of up to 30 miles per hour but still have time to take in panoramic views, with most of the rides standing at 300-plus feet tall.
The attractions have been plagued by technical problems since they first debuted, with Knott's Berry Farm's eventually opening several months late in August 2011.
