The engineers did their job.
The people running the park did not.
Be interesting to know if routine inspections were actually being performed......wouldn’t be the 1st time someone rubber stamped paperwork......and if thats the case, gross negligence comes to mind.
BTW, if by some chance that damage is indeed earthquake related, then no, the engineers didn’t do their job.
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.
