On Friday evening, a woman died after being flinged from the Texas Giant roller coster at Six Flags over Dallas. Witnesses say the woman flung from the ride after her safety belt became loose. The accidental death did occur while the ride was in motion, but authorities have not said at which point in the ride the woman was killed. The woman was on the ride with her daughter and son-in-law. 

The ride, known as the tallest steel-hybride roller coaster in the world, has been operating in Dallas since 1999. It climbs 14 stories high and drops 79 degrees, while carrying 24 riders at a time. The ride was first opened as an all wooden roller coaster but underwent a $10 million re-vamp to install the new rail system and was reintroduced to the public in 2011. 

The woman's body has fallen to a platform below the roller coaster, and fire crews used a ladder truck to recover her. 

"We are deeply saddened to share that earlier this evening an adult woman died in the park while on the Texas Giant. Park medical staff and local paramedics responded immediately. Since the safety of our guests and employees is our number one priority, the ride has been closed pending further investigation. Our thoughts and prayers are with the family and friends during this difficult time," the statement said.

Six Flags has responded by temporarily closing the area of the park that the woman died in, and by shutting down the Texas Giant until it can be fully assessed. The only other reported death happened in 1999 when a woman died after drowning underneath a turn-over raft on the ride Roaring Rapids.
