I think the issues that have been raised are the issues that have been talked about fairly commonly across the previous committee meetings. I leave that to the committee to further pursue, but as we noted one good example is the Transportation Safety Board's recommendation on voice and video recorders. That's an issue of some complexity, and we're working closely with the Transportation Safety Board on analyzing the problem and considering the options. When the study we're currently involved in is finished, then we can look at what might be appropriate for regulation.
