I'm probably going to regret getting into this fray, but here goes:
First, I enjoy Mission:Space. I'm not advocating they tear it down. And I'm not blaming the ride per se on any tragic happenings. But I am curious as to how many park guests need to die after going on a ride for some people in this forum to at least admit that perhaps Mission:Space DID play some small role in it. It's OK if you love the ride and love Disney and want it to stay open for eternity. But at least acknowledge that maybe the ride had something to do with it.
It seems to me that if two people die within a year of each other (regardless of their ages, medical history, etc.) then all of us need to take a step back, take a deep breath and ponder whether Mission:Space is doing more harm than good. Right now, I'm on the fence. On one hand, it's enjoyed (safely) by hordes of people every year. But on the other hand, whether it caused the deaths or not, it is becoming a liability for Disney.
