Air Mobility Command Museum @ Dover AFB by Ewingjr98
Located on the south side of Dover Air Force Base is the Air Mobility Command Museum dedicated to the history of aerial transport. There is an indoor museum as well as several static displays outdoors. To get there, take Delaware Route 1 past Dover AFB and turn northeast on Route 9.
The museum is free to the public, and you might get to see a few US Air Force jets take off from Dover AFB's nearby runway.
