A woman died Friday evening in an accident while riding the Texas Giant roller coaster at a Six Flags amusement park in North Texas, authorities said. The accident happened just after 6:30 p.m. Friday at Six Flags Over Texas in Arlington. Park spokeswoman Sharon Parker confirmed that a woman died while riding the coaster at Six Flags Over Texas in Arlington but did not specify how she was killed. A family in line behind the woman who fell told MyFoxDFW.com that she was on the ride with her daughter and son-in-law. The family said her seat restraint seemed to go down normally before the car left. They said when the train came back, the seat restraint was down. The family said the woman's daughter and son-in-law were calling for help. They were screaming, "We need to go get my mom!" Witnesses told local media outlets that the woman fell from the ride, which is billed as the tallest steel-hybrid roller coaster in the world. "She goes up like this. Then when it drops to come down, that's when it (the safety bar) released and she just tumbled," said Carmen Brown of Arlington. Brown said she was waiting in line to get on the ride when the accident happened. Read more: http://www.foxnews.com/us/2013/07/2...-flags-roller-coaster-in-texas/#ixzz2ZfYjsBGn
