Citizens want to be reassured that the transportation systems in this country are working effectively and safely, and that if you board a plane, train or ship, you're going to arrive safely, etc. I understand that.
Trying to show somebody a safety management system is very difficult, because it's not a book on a shelf. It's got to be something that permeates day-to-day operations and mindsets.
I coined a phrase once. It's basically about looking for trouble before trouble finds you, and then taking steps to address that.
