No, that's not what I'm saying.
We have to look at the evidence that we have before us. I would very much welcome that Transport Canada is going to do a study on work duty times of pilots, on fatigue, on circadian rhythms, because I think they need to do that. It's an important safety issue. However, what I'm telling you is that if you look over the last 20 years at all of the aviation investigations, we don't have evidence that it was a causal factor in a number of investigations. It's not popping out in our investigations. Our job is to investigate from a scientific perspective, and we have to be mindful of the evidence that we uncover, sir.
