The Transportation Safety Board has raised a number of issues in the last few years, and has drawn more attention to those with their watch-list. That has been very helpful to Transport Canada, in helping us to focus on some of the highest safety priorities.
We have looked at all of the outstanding recommendations. We've been working closely with them to go back through the set of recommendations that exist.
I can give you reasons, which are probably not entirely satisfactory unless you look at each individual recommendation. There are instances where, in our view, the technology has superseded the recommendation, so in some cases, we would not necessarily be moving forward with a particular approach to a recommendation.
There are situations where the recommendation in principle is a good recommendation, but when you look at the practicality of implementing it....
I'll use the three point shoulder belt recommendation for older aircraft. When we looked at the complexity of doing that and worked on that, we found that the structure of these older aircraft would simply not support that particular recommendation.
One of the things that we've been doing with the Transportation Safety Board is working with them to clearer in defining where we see some of those challenges. Sometimes we've been too slow, and so we agree that we have to move more quickly.
