Interesting stuff. The link didn't work when I tried it, but Wiki has some info on Duke Field (Eglin Field #1):
http://en.wikipedia.org/wiki/Duke_FieldAccording to Wiki, six survivors from the Doolittle raid held a reunion at Duke field in 2008.
Here is a Wikipedia link that talks about the various Eglin fields (scroll down about midway for a description of each field):
http://en.wikipedia.org/wiki/Eglin_Air_Force_BaseApparently Field #3 was used for the fictional set of the movie 12 o'clock high. I was curious if that was where Paul Mantz did his famous B-17 belly-landing, but a google search said that it was filmed at Ozark AAF in Alabama.
I looked at Eglin Field #2 with Google Earth, initially it looks abandoned but after zooming in there is a C-130, what looks like a couple of F-16s and perhaps 2 old F-4s. This underscores what Don said about being used for special ops.
Fun stuff, thanks for posting about it.
