At least that puts to rest the rumour about the ride coming apart.
We shall see what caused this, but very sad when things like this happen, particularly as it seems everything was working correctly and the attraction was, no doubt, tested quite thoroughly.
I don't think we can read much into these statements from UNI. They are basically saying "we did what we are supposed to" -- not that "the ride was safe" or "it had to be X". All they are saying is (paraphrasing) "we followed the book" and that the ride was found to be operating AS DESIGNED. That doesn't mean the design was right, safe, or without oversight. It just means things operated as they were expected to within the existing design.
This is critical because so much of the regulation is written around the operator following the requirements of the manufacturer and their SOP. All they are basically saying at this point is "there wasn't a mistake made by Ops" or some known maintenance gap.
For all we know, the ride could have been designed for something to break off under a criteria, and it doing so would still be "everything worked as designed" -- That's an exaggeration, as we know it's highly unlikely for the design to include anything intentionally coming free on a high speed vehicle like this.. but it's used to illustrate the point. The statement is only to say "everyone was doing as they were told to do" and that the ride system did what was EXPECTED of it.
The problem is -- when the design itself is the issue or things that were not covered by the design. That's why it's still possible for the Ops or Ride system to be at fault, while not contradicting those kinds of statements.
UNI is just saying everything was done properly and there was no observed failure of the ride to do what it was supposed to do. The grey area is, what if that was insufficient?
Personally I find the top of unconscious riders an interesting subject.. something I can't imagine the ride manufacturers HAVEN'T considered... especially given the lack of rider monitoring on trains so I find it hard to believe that is the sole factor in this accident. Plus, I find the lack of witness reports also highly unusual. If the guy was flopping around like a rag doll... someone would have noticed and I don't think all leaks would be tight enough on this.
I'm still of the opinion that this will be some combination of factors and unusual consequence. Like maybe trauma caused by excessive movement or some freak combination. Freak like, you can fall and hit your head hundreds of times in your lifetime without any issue.. that doesn't mean you can't hit your head and die that one time.
Without more details about the injuries, it's just wild a** guessing at this point.
