I think we have all learned in the last year some very important lessons, and believe me, just within our department we have spent 8,000 hours as part of the process of understanding what happened and, at the same time, finding a fix for it.
As with all organizations, if you do not use the opportunity when something like this happens to improve your organization, then you are failing. I can tell you that at Transport Canada we're very aware of the fact that we have to look at ways to improve our validation process and, perhaps if I can put it in more colloquial terms, be a little more skeptical in the future as we approach these.
It has served us very well in the past, and Canada's record of air safety is really quite outstanding, but this is an opportunity for us to improve.
