A State Fair spokesperson said Thursday's malfunction was mechanical while Friday's issue was electrical. The ride, which was made in Holland, is the only one of its kind in the U.S., so reaching an expert on its mechanics is difficult.
Prior to being set up at the Minnesota State Fair, the ride had been featured across the border at the Wisconsin State Fair. Officials there say the ride had similar problems earlier this month.
The ride reopened at 8:10 p.m. on Saturday.
The website for Mighty Midway Attractions describes the Stratosphere ride as "a soaring gondola" that flies riders in a circle around a 190-foot tower, offering views of the fairgrounds from above and beyond.
