I can't imagine being on a ride and it literally breaks apart while in motion!! That's exactly what happened on the Fireball ride at the Ohio State Fair during opening day. One person was killed and seven others injured.
A video is online that shows several people on the Fireball ride seconds before parts of the structure, including a full row of seats, split up and fell. Just to give you an idea of the ride itself, The Fireball consists of at least six rows of seats that spin around 40 feet above the ground as the entire structure moves like a pendulum. Well, the pendulum actually broke apart while it was in motion.
