OK so they had a ride which they knew had an issue that was dangerous, didn't communicate that danger to staff, knew what modifications to make to solve it but didn't do them, removed an alarm which may have given the ops staff a chance to abort the disaster, and didn't train tech services properly. They also lied to the coroner, stopped spending on maintenance, and appeared to have deficient processes in place. That's basically the story yeah?
I mean what are you even supposed to say to that? Dreamworld is the only theme park in the world that would actually benefit from an advertising campaign that goes 'Our old maintenance manager, ops manager, CEO and Chairperson of the board are in jail now, it's safe to come back'
What's scary about it is the people who modified TRR are the same people who are still looking after things out there. The same people who looked after the TRR also put the cages on the log ride.
