Playing the devil's advocate-
In Disney, we're hearing about the deaths usually due to a pre-existing, although usually undiagnosed, medical condition after riding.
With this one, we're hearing about "minor head, neck, and chest injuries" per the headline.
I am sure that if there had been even a single fatality, it would have been all over the national headlines. I did hear something about this on DC radio this morning though.
Regardless, how unfortunate. I hoep everyone recovers quickly and that they sort out what's going on with the ride.
