Air Force veteran Ken Johnson checks out the cockpit of an A-10 Thunderbolt II aircraft at Selfridge Air National Guard Base, Mich., June 24. Johnson visited the base as part of a veterans reunion. The veterans all served at Selfridge in the 1960s, when the base was an active duty Air Force installation. They were all part of the 1st Fighter Wing, which was then located at the base, operating the F-106 Delta Dart.
