Witnesses: Woman Falls To Her Death From Texas Roller Coaster

A woman died Friday at Six Flags Over Texas near Dallas while riding the world's steepest wooden roller coaster, the park confirmed Friday night.

The Texas Giant, a 14-story-high, 4,900-feet-long roller coaster that is among the premiere attractions at the park in Arlington, Texas, was closed, the park said in a statement.

The park said in its statement that the woman died "on" the ride, but park visitors told NBC 5 of Dallas that they saw her fall from the roller coaster shortly after 6:30 p.m. (7:30 p.m. ET).

They said workers on the ride directed paramedics to her location.

Nadine Kelley, who had been waiting in line for the ride, told NBC 5 of Dallas that riders who were sitting behind the woman said that "right when they came down off the first bump and hit that first turn, she flew out."

The woman was accompanied by two children, who were "hysterical," Kelley said. "They were saying that their mother flew out of the car."

"It was sad. It was very sad," she said. "We kept telling them to let them out because they were hysterical. The daughter and the son said, 'We have to go get my mom. We have to go get my mom.' We were kind of in disbelief, and we just said a prayer for her."
