In all honesty, most of that is common sense, and it is very diffrent from that show. (the secret worl of amusement parks. three years old). I must say I did learn a few things from that show though. They also do not say anything about the rides sound. I could, also, have gone on about how the Lines are designed and exactly how they know how long to make them. I didn't steal anything from that show.
Jeff, It may have not been at first, but they had to know that at least the Mantis would be loud. They certainly must have thought it would help and did nothing to stop the noise. Although it probably was not top priority, it must have been noted that it was loud.
