Ride operator, passenger injured at Maryland fair
(August 17, 2010) - At the Montgomery County Agricultural Fair in Gaithersburg, Maryland, a ride operator was struck by a rotating swing ride called Vertigo. He climbed over the metal fence that surrounded the ride and entered the path of the swings when he noticed that the swings were colliding with another section of the fence.
Witnesses said it appeared that the foot of at least one rider collided with the fence as the ride lowered back to the ground. The fence was then partially dragged into the path of the ride. Some swings collided as the fence became an obstacle and interfered with the normal rotation of the ride. One child who was on the ride suffered minor injuries when he collided with the fence.
A news crew from WTTG FOX 5 was on the scene filming for another news story and captured the accident on camera.
The Vertigo is manufactured by A.R.M. Inc. of Ohio and operated by Powers Great American Midways. It passed an inspection when the fair opened last week, but has been shut down as investigators work to determine what went wrong.
UPDATE: A spokesman for the fair said that the swings, which are designed to stop rotating once they are lowered inside the fenced-in loading area around the base of the ride, did not stop, causing the riders legs to collide with the fence.
