The information on the available aircraft is a job for professionals who know what they're talking about, but it also entails access to highly classified information, which we have access to through our allies. In terms of the joint strike fighter, we have full access to our membership in the memorandum of understanding with the partners, without which we wouldn't have that access at all.
I'd also say that within the department a pretty rigorous and often bloody challenge function goes on. The vice-chief, his staff, force development staff, challenge the Chief of the Air Staff on their views on capability. I, frankly, am known to be pretty difficult in challenging requirements, not because I disagree with the environmental chief of staff, but they have to be defendable in the town. They have to be defendable to Treasury Board and Privy Council Office and the Department of Finance and the Department of Public Works and Government Services. So although many observers don't get an insight into the interior workings of the program management board, the joint force development board, those are difficult bodies, and when that advice goes forward through the Chief of the Defence Staff to the minister, it is pretty rigorous.
