B-18A Bolo bomber on display at the US Air Force Museum in Dayton, Ohio. This B-18 was assigned to Wright Field, the current site of the US Air Force Museum, during WWII. It served as a base hack after the war until it was retired. It managed to avoid being scrapped, and eventually was added to the museum collection. She sat outdoors for many years before being restored to static display condition about the time that the second main hangar building opened.

Note that this aircraft has the classic bomber nose of the B-18A series. The bombardier sat in the upper level of the nose, and had a clear view to the ground. The nose gunner used the lower level, and fired a single machine gun that was mounted in a clear plexiglass swivel mount.
