For a small-town flight museum, this place was more impressive than I expected. Founded in 1996 by Apollo 8 astronaut Maj. General Bill Anders, the museum hosts a collection of artifacts from WWII, Korea, Vietnam, and the Gulf War. But what I really enjoyed was the up-close look and touch of some vintage aircraft, all in flyable condition.
You can view the full collection on their website - http://www.heritageflight.org/content/ - under the "collections" menu. Unfortunately, it is rare that the entire collection is there at one time. Many of the aircraft travel to various airshows in the region, but at any one time, you can catch some very impressive machines at the hanger. Also, the hanger is not huge, so some of the planes are stored in adjacent facilities.
On our trip, we saw the P51 - Mustang, the PT19 - Cornell, the PT13 - Stearman, the TD6 - Texan, the O2 - Skymaster, the H16 - Souix (MASH Chopper), just to name a few.
