I typed that last post before watching the whole video.
That was frigging horrible
He looked like a kinda big kid i don’t see how he slipped out except for mechanical failure.
RIP
Really big for a 14 YO from what I can see maybe in excess of 200 lbs.
The last one or two of these types of incidents involved obese people. It is likely be that they can't be restrained properly because of their girth.
Mostly it becomes a CG or containment thing which indicates poor design of the restraint system or inadequate screening of the riders. Either way, someone will pay big time for this one because one size doesn't fit all..
