Mid-America Air Museum
From their website:
"The Mid-America Air Museum in Liberal, Kansas is one of the country's largest air museums and home to more than 100 aircraft. The museum's collection was started by the late Colonel Tom Thomas, Jr., who donated his personal collection of over 50 planes to the museum.
It is an impressive display, although the airplanes feel more crammed into the hanger than displayed. I believe that the typical visitor will find the Air Museum is good for about an hour's visit. But with more room, better organization and more historical information, the Mid-America Air Museum could be a regional travel destination."
