Thank you.
Mr. Fonberg, we talked about the fact that for many years DND has typically used 20 years to project life-cycle costs. I would suggest that's because of the risk of all the unknowables: cost of fuel in 20, 30, or 40 years; missions the airplane might undertake; technological challenges that come along. My recollection of the F-18 program is that the same process was applied there. We had projected the airplane to be for phase-in plus 15 years, which would have taken it to 2003, when we'd be looking for new aircraft, which in fact we have been doing.
Could you comment on the fact that this has been the methodology through successive governments of both stripes, notwithstanding what's going to happen going forward?
