I was last there about 10 years ago and they had just opened up a new building - a museum/hangar/gift shop sort of thing. They were still recovering from the tornado that had hit in 1979 and there were still some damaged aircraft lying around in 1995 (tornado really wrecked the place). It was a nice place to visit back then and I can only assume that they have gotten a lot better since.
In fact, looking at their website,
http://www.neam.org/default.asp, it looks completely different (and much improved).
By the way, try to go on an "open cockpit Sunday". They actually let you sit in some of the planes. My best memory of the place was sitting in a P-47D, working the stick and rudder and pretending that I was flying over Germany in WWII

- my girlfriend at the time thought it was a bit silly but I did not care!!!!!! Besides, we broke up shortly afterward - Coincidence????
Other cool thing is that the access road to the musuem runs along the perimeter fence of Bradley International and you can park along the road and watch the planes land - at least you could prior to 9-11.
