Actually, sir, a lot of the advice we got was in terms of the patterns, as Mr. Page said earlier, that were emerging in terms of development. There was a lot of expert advice that said that in fact it's not as unique as one might think. We've talked about different generations of aircraft, but in terms of a capabilities increase, there is a long history of aircraft, every generation having new.... They're larger, they're heavier, they have more capabilities. But in fact if you look at the time series in our report that was logarithmic, you'll see that the dispersion around the trend lines is actually very tight. It suggests that actually, as you go from generation to generation, these aircraft exhibit commonalities.
