The circular swing ride stalled, leaving 20 people stranded 300 feet (91m) in the air for nearly four hours. No one was injured, but the evacuation, which took three hours and forty minutes, is one of the longest on record for any amusement ride. Two weeks earlier the same ride stalled and left 15 people stranded for about three hours and in July, Windseeker at Carowinds near Charlotte, North Carolina stalled and left 25 riders stranded hundreds of feet in the air for nearly three hours. In June, the same ride at Cedar Point in Sandusky, Ohio left 29 riders stranded 150 feet (46m) in the air for more than an hour when it stalled. All six of the Windseeker rides operating at parks throughout the Cedar Fair chain were ordered closed for the rest of the season. Source
