No, the engineers who designed that thing did their job. There were sufficient safety factors built in so that a single structural failure like that wouldn’t allow a catastrophic collapse.

+++++++++++++

I agree with your statement as I don’t believe structural engineering is the causal for this failure. This rollercoaster is the parks NEWEST. The root cause of this failure needs to be understood. Was it faulty material? Was it a faulty weld where the vertical and angular trusses are joined? Was there a serious misalignment going back to day one when this coaster was assembled? Consider when the track support was bolted to the vertical structural support trusses. If this joint is not lining up and the bolts were just cranked down to force the structures together you have a BUILT-IN stress in the system that is not supposed to be there. No way a failure of this nature should be occurring based on the structural engineering that is used to design these machines. Need ROOT CAUSE.

The root cause, in my opinion, is the root pass on the weld.
Bad root can’t be repaired. It has to be ground out and done again.
It doesn’t matter how great the filler passes are.
Bad root equals bad weld.
I wonder what standard roller coasters are welded too?
Gotta be more stringent than D 1.1
