Don't know if any injuries happened but I still don't have the nerve to go on that insane water slide the Summit Plummet at Blizzard Beach. I get chills when I walk by there in the summer.
I don't have the stats in front of me, but I think its more likely you will be killed on the DME ride to WDW than it is to be killed on any attraction in WDW.
Mission Space killed two people (I know, I know, pre-existing medical problems) but I love that ride and I go on it when ever I am in EPCOT!
In some WDW attractions, I would not mind to be evacuated, like POC, that would be cool to see it with the lights on.
On the other hand, Space Mountain, that ride sounds like its going to break apart an any moment, but I still ride it ever chance I get. It seems every time I am near that ride the standby magically changes to 80 minutes and I just walk by
Another ride that I love to ride but makes me nervous is Test Track. When we are in the high speed part, I cant help thinking this car is going to fly off the track like the HO cars I used to play with as a kid, BUT I still love it and still go on it!
Everyone has irrational fears about a lot if things, I know I do.
As for the Skyliner, they probably addressed the issues and there will be no more problems, my brain keeps coming back to the evacuation plan if there is another "malfunction". I would not want to be stuck up there in August, during the day, in the hot sun, with strangers.
Another irrational fear? Perhaps. Perhaps not.
