A woman died while riding a 14-story-high roller coaster at Six Flags Over Texas.
A statement from the amusement park said... "an adult woman died in the park while on the Texas Giant. The ride has been closed pending further investigation."
Witness reports say the woman's safety restraint may not have worked properly and she mentioned her concerns to an attendant.
A witness said, "He was basically nonchalant. He was, like, 'As long as you heard it click, you're fine.'"
The witness said that during a sudden shift on the ride, "the lady basically tumbled over."
The person behind her empty seat said, "she fell out there—just flew out."
The ride includes three turns of less than 90 degrees and has a top speed of 65 mph, but there's also a 147-foot drop.
