It all comes down to the parents. I would not let my kids ride a ride that is so obviously violent. I ran into a smart parent one day outside of Snow whites scary adventures and they asked me if they thought the ride would be too scary for their kids. I looked at the kids and said yes ebcause they were very young. If you get in line for a ride with as many warning signs and videos as Mission Space has, and you still let your kids ride, youa re failign them as a parent. Common sense shoudl tell a parent that the ride may be too much for a 4 year old or even a 10 year old to take. I am not surprised a 4 year old died on thsi ride because i asked myself why is a 4 year old on this ride? It makes no sense to me because it is so obvious that the ride is violent, Disney says so. Of course it is tragic what happened. However it comes down to parents being parents, and knowing what is best for their child. I wouldnt let my 4 year old ride Tower of Terror or the Rock and Roller Coaster or Space Mountain. Kids of that age don't have control over their bodies, Plain and Simple.
