World's largest military aircraft museum is in Dayton, Ohio

There are 350 aircraft and missiles on display at the National Museum of the United States Air Force. Celebrating its 100 year anniversary, the museum boasts over 20 acres of indoor exhibit space in four huge hangars. The major galleries include Presidential aircraft, early years of aviation, World War II, Southeast Asia War, Korean War, missile, space, and global reach.

This video includes just 5 of the many highlights of this museum. I would recommend allowing yourself at least a day, if not two days, to view the aircraft and take in the history.
