When the lights were all been turned off and the doors locked, all that was left of the largest military installation in the Jacksonville area and the South's only Master Jet Base will be 30,000 acres of land, some buildings and equipment, and memories spanning six decades. The base officially closed September 30, 1999. Approximately 17,200 acres were transferred to the private sector, the remainder was transferred to NAS Jacksonville. (globalsecurity.org)
