There are two components to that question I'd like to address: one, how Canada would prevent that; and two, how our certification partners, as well, have learned to prevent that.
First I'll speak to the Canadian perspective. I can say without doubt that the approach we take with our Canadian manufactures is a much more integrated one. Our experts, the experts in the national aircraft certification group, are quite significantly involved in the certification, review and analysis, even in those components that we may delegate to our manufacturers. It is a mutually respective process, which prevents that sort of instance we saw with Boeing where information was withheld from a certification partner. From a Canadian perspective, we don't believe that sort of situation or environment would occur, given the work that we have directly with our manufacturers.
From an international perspective and the instance that we saw with Boeing, we believe that the reviews and inquiries that have been undertaken within the U.S., and the recommendations that have been put out, which the FAA has committed to implementing, will prevent a similar problem from occurring in the United States again, particularly with regard to Boeing.
A secondary set of assurances goes back to my colleague Dave's comments on what we've learned around how much we engage and the areas that we engage on in our validation process. Our validation process will be much more thorough in a number of different areas where we see there may be a chance or an opportunity that the certifying authority might not have the full information for what's being looked at.
