They probably now wish they had have changed the system back when in 2015. It could have saved them a lot more money in the long run (visitor numbers down now, lawyers, lawsuits) not to mention the terrible loss of four innocent lives.
So from the testimony this week, management was incredibly aware that it was a dangerous ride when a certain chain of events occurred. That they didn't try to minimise the risk with extra monitors and more CCTV at minimum and a one stop complete shut down button is baffling.
What is really interesting is that two paramedics and a nurse are three of the four in the lawsuit against Ardent. While the fourth, the engineer, could reasonably expect to never have to experience what they did that day, it could be argued that the paramedics and (trainee) nurse would reasonably expect to witness something as horrific at some time in their career as they did that day and hence they might not be as successful in their damages claim. Food for thought
