Darrel Anderson, 76th Maintenance Support Group’s Tinker Aerospace Complex program manager, briefs Under Secretary of the Air Force Erin Conaton on the capabilities of the Tinker Aerospace Complex, June 6, 2011, at Tinker Air Force Base, Okla. The building and the surrounding facilities were brainstormed in February 2006 when the General Motors plant in southeast Oklahoma City unexpectedly closed. In 2008, Oklahoma County purchased the facility from GM and leased it to the Air Force. The under secretary visited Tinker Air Force Base, June 5-6, 2011, to meet with base and community officials and see first-hand the base’s efforts to support warfighter needs.
