I think we address that in the chapter on safety management systems. We feel they've got to go right back to basics and talk to the employees who are involved in the risk and have an interest in the mitigation of the risk.
That's what safety management systems are about, but it doesn't seem as though that happened, or that when they did it, the companies had specific meetings at which they sat down and said, “We're going to demystify SMS for you. We're going to tell you it's about making sure that you go home at night.” That's what it's about.
