Rider claims Goliath's restraints kept popping open months before the fatal fall

An entrepreneur who rode Goliath at Six Flags Over Georgia a few months back says the coaster was already showing warning signs long before this week's deadly accident.

Long lines and a pulled train

Nick Specter-Vlacic says his visit came with long delays while he waited to board. He claims one of the trains was taken off the track again and again for testing because its restraints would not stay shut.

He says he has a hard time believing the park was truly blindsided by what happened Monday.

Nobody has shown that the problems he describes are tied to the accident.

What happened Monday

Hassan Jihad Ibn Kariem, 42, was thrown from Goliath and hit other riders as he fell. Several more people were hurt.

Six Flags then shut down 9 similar coasters at its parks across North America for the time being while investigators try to pin down the cause.

The park's response

The Atlanta-area park plans to welcome guests back Friday. There is no word yet on when Goliath will be back in service.

A park spokesperson said the safety of guests and workers comes first. The park said it cannot talk about the accident or the rides that are closed for now. It added that it sticks to strict ride checks along with upkeep and safety rules it says top industry norms.
