We spent a lot of time with people who worked with the F-22 Raptor—retired Pentagon officials, the GAO, the Rand Corporation—a lot of people who have a great deal of expertise over generations of fighter aircraft. In particular, one of the reasons we collaborated with the firm in the U.K. is that they actually provide similar advice to the U.K. National Audit Office and the U.K. Ministry of Defence, and they do this on a lot of fighter jet programs. What is interesting, actually, is that there is quite a bit of commonality associated with the program.
