The U.S. Air Force can trace its roots back to the Aeronautical Division, Signal Corps, which was formed as a part of the army in 1907. In 1947, after a number of changes, W. Stuart Symington was sworn in as the first Secretary of the Air Force and it became its own branch. Among other things, they assist in the recovery of troops and air support of other armed forces. This Mini Bumper Strip Magnet is for retired members of the Air Force and is a great way to show pride in their branch and the service that they gave to our country.
