I have been visiting the park for almost 13 years and have never once seen it happen, or been on it when it happened. This "thingy" you speak of is called the car. They are not wires, they are cables, and I just looked it up to see absolutely no citation of when this supposedly happened. I'm going to pass that off as yet another silly rumor.
You may want to consider switching to Firefox for your browser, they have a spell checker. I get very annoyed very quickly by people who are old enough to understand how to use a computer, yet they can't type to save their life.
