I find all the pictures posted so far fail as images of the overall memorial. Here http://www.af.mil/photos/index.asp?g...ID=2259&page=2
is a collection of images from an Air-Force related site, with several aerial views. Those are much better for the purpose.
This site also includes sculptures of individual AF personnel in uniform, and I don't think as highly of those pieces as the overall triple spire.
Overall, I disagree with evaldart on the relative merit of buildings for business and of memorials. Memorials serve a necessary purpose, and nothing else serves as well.
