Yeah,this is both scary and sad.The mother fell into her death while riding the Texas giant roller coaster at six flags.There were people on the ride and in line who saw the whole thing.

And this is just one of two amusement park accidents overnight.And ABC'S Rob Nelson is one the story.

Good morning,guys.The tragedy unfolded surely before 7 p.m last night.A mother fell from that coaster whose young son in the seat in front of her and witnesses simply stunned and shaked by what they saw.

This morning authorties in Texas are searching for answers after a woman fell her death from a 14-story amusement park roller coaster.On Friday,the unidentified woman,along with her young son,was riding the Texas giant roller coaster at six flags in Earlington Texas at 152 feet.It's built as the tallest steel roller coaster in the world,full of sharp turns and steep drops.Camon was next in line for the ride when she saw the woman tumbled to her death.

It didn't hit me until we got down,right down to the bottom.And I said she was no bigger than I was,like that could be me and I was...

Others who were on the ride at that time took the twitter,one man wrote,literally just witness someone fly off the Texas giant two seats in front of me,in another tweet he points to a possible cause,restraint came undone,coaster turned and she was gone.Investigators did not came to the ride to restraint system,but say this is not a criminal investigation.Park officials have not released any detail about what caused the tragedy but released this statement,since the safety of our guests and employees is our number one priority,that section of the park has been temporarily closed.Another passenger who was just two cars in front of the victim says it was the fright of his life.

Other families were crying,screaming and looking for her.They didn't what was happening,they just heard that someone falling down from the roller coaster.So at that moment there was a panic.

And that was not the only amusement park accident last night,at S park in Ohio,seven people suffered minor injuries on the shook the rapids ride when their boat suddenly rolled backwards down to hill and then flipped into the water.Witnesses said the passengers were trapped inside the boat because of their saftey belt,forcing park officials,medical personnels even fellow visitors into that water to save them.

I've reminded that these rides are fun but they can also be dangerous.All right,Rob,thank you.
