Thanks, and no, I think you've covered that aspect of it.
I want to move to my main line of questioning. This is in respect to safety management systems.
From what I've been hearing from the evidence.... Of course, there are regulations relating to safety. On top of that there's a safety management system. It's meant to augment what's already there. It's more flexible. I think someone referred to it as holistic. Of course, there was a survey that seemed to go against that trend. You did say there's some difficulty in getting a handle on measuring the survey or understanding exactly where it's going. I think it was Mr. Deveau who said that questioning the value of SMS is not a rational argument. I think one other comment was made that a higher risk because of SMS is often unfounded. I'm not sure who said that. Perhaps it was Mr. O'Rourke.
Can you indicate why you feel it's not a rational argument, Mr. Deveau, and why you feel it's unfounded, Mr. O'Rourke? Then I will have some questions following from that.
