Thank you, Madam Chair, and thank you for being here today.
There's a strong sense of déjà vu because, of course, we had the rail safety study as well. I guess the question that comes up is about the ability of the large and rather well-heeled operations to have very robust safety management systems versus the smaller operators. Rail or air, it seems to be about the same story. Is the safety management system platform or approach or model really performing as expected, so people can be assured that these companies are doing the right things in the right ways?
