A worker was killed at the Tulsa, Okla. fairgrounds on Saturday morning after he and his partner were trying to fix a pulley on a gondola ride 90 feet above the ground and the maintenance bucket they were in ruptured and fell below.

"They were harnessed up so it left them dangling about 85-feet in the air. One of the workers had a traumatic head injury, went unconscious on the way down and went into cardiac arrest," Stan May, captain of the Tulsa Fire Department told USA Today.

The victim died of his injuries at a local hospital. His name and age were not made known. The other victim was alert and is now in stable condition.

Captain May also revealed that the worker who died may have struck his head on one of the snapped braces. He was unconscious when the rescue crews got a hold of him and his partner at about 10:40 a.m. and went into cardiac arrest, the New York Daily News reported.

Rescue crews revealed that the actual rescue was quick but they had difficulties in getting in to the rescue site, according to the Atlantic Journal Constitution.

The Tulsa fair is expected to be opened to the public on Oct. 1.
