It is not the first time an accident involving a ride has happened at the N.C. State Fair.

The most recent one occurred in 2009 when a worker fell while trying to break down the 'Flying Bobs' ride.

Years earlier in 2002, a worker was killed when he slipped and was hit by the 'Bonzai Ride.'

And in 1998, three riders were hurt in an accident on the 'Zyklon' roller coaster. Three cars collided when a wheel bearing on one of the cars seized up. The riders suffered minor injuries in that incident.

In the meantime, the 'Vortex' remains closed. The fair is operating on normal schedule.

Fair officials said they hope Thursday's "isolated thing" will not impact people enjoying the last weekend of the fair.

"I am confident my grandchildren can ride the rides ... and they will," State Agriculture Commissioner Steve Troxler said.
