Sad to hear of a tragedy for this family. This article did not mention whether the child has any kind of pre-existing conditions, so it will be interesting whether the family did not follow the ride safety rules, or whether it was a freak illness or unknown health condition that was triggered by the ride.
2 G's are not a lot but doesn't it last a bit longer on this ride than on your typical rollercoaster?
edit: Regarding that survey question, I acutally had to vote yes. Back in Adventure World (now SFA) I got whiplash on an Arrow shuttle. It actually hurt pretty bad and after trying a few more rides, I eventually went to first aid and had to lie down for a while, got an exam, and then went home.*** This post was edited by RavenTTD 6/14/2005 12:38:08 PM ***
The forces on a commercial jet taking off are less than 1.5 g's. That's total from gravity and the acceleration. The acceleration itself is only around 0.3 g's as compared to launched coasters which can have linear accelerations as great as 2 g's. We notice the forces a lot in a plane because they are extended and in a direction different from how we normally feel gravity.
The article mentions the large number of medical issues reported from the ride. This is probably because the 2 g's is extended and also because this ride probably gets more older riders than the typical thrill ride.
I think the restrictions need to be re-thought. A 4 year old, regardless of size, isn't physically able to withstand that force without some sort of pain to his body. I feel immensely for the family, this was their vacation. However, 4 seems a little young to take on a ride that has so many warnings and restrictions.
