Cobb County police said several others suffered injuries. One witness told WXIA the falling man appeared in his souvenir picture from the ride. Aerial video from WXIA showed other riders being evacuated.
The Six Flags website lists Goliath at 210 seconds, with a top speed of 70 mph and an elevation of 200 feet. The park released a statement: "We are deeply saddened by the guest incident at our park today. Our thoughts and heartfelt condolences are with the guest's family, friends, and loved ones."
The death comes nearly two weeks after Six Flags Magic Mountain in California announced it will permanently close its ride X2. That decision followed a CNN investigation that found more than a dozen reports of serious injuries and hospitalizations tied to the coaster, including at least two deaths. Magic Mountain President Brian Oerding wrote in a blog post that X2 "consistently passed a multitude of safety tests," but the park decided to close it anyway.
Two women ended up in the same Santa Clarita emergency room with brain injuries after riding X2 just six days apart in July.
