Universal Orlando in Florida is altering its signature ride.

Officials announced this week they will no longer launch the Dragon Challenge's twin roller coasters simultaneously following an internal investigation stemming from two recent incidents.

For more than a decade, the ride has featured a "high-speed chase between two coasters." The two coasters passed within 18 inches of each other as they speed along intertwined tracks at up to 60 mph.

The Orlando Sentinel (http://thesent.nl/oNlC4K ) reports the park started launching the coasters on a staggered basis after two riders were struck by loose objects.

In one case, a 52-year-old man suffered a lacerated right eye while riding Dragon Challenge July 31. The man's lawyer says he had his eyeball removed.
