Keith, you are arguing with yourself! According to the opening gambit the USAF Museum made all others pale into insignificance, but you come up with another candidate for that title. So what's it going to be? Dayton or Smithsonian?
In fact there are a number of candidates that are (gasp at the mans effrontery) NOT in those there United States! Some (splutter, cough) are even in Europe (Yurrup for some Americans). There may even be other worthy candidates OUTSIDE Yurrup, too.

And the 8% figure is WAY out-of-date. Don't know the actual number, but it's several times that.
