On Oct. 1, 1973, Bush received an honorable discharge from the Texas Air National Guard in order to move to Boston and attend the Harvard Business School, where he was still obligated to find a unit in Massachusetts to fulfill his remaining nine months of duty, or face being placed on active duty. Once again, Bush made no such effort. But the Air Force in Denver, acting retroactively, in effect overturned Bush's honorable discharge and placed him on "Inactive Status" effective Sept. 15, 1973. When Bush left Texas, his personnel file was sent to Denver for review. The ARPC quickly realized Bush had failed to take a required physical exam, his Texas superior could not account for his whereabouts covering nearly a 12-month period, and due to absenteeism Bush had failed to "satisfactorily participate" as a member of the Texas Air National Guard. Bush's "Inactive Status" meant his relationship with the Air Force (and the Guard) was severed and he was therefore eligible for the draft.
Soon afterward, large gaps began appearing in Bush's paper trail. Lukasiak concludes that only last-minute intervention, likely from Bush's local Houston draft board, saved him from active duty, as well as finally securing his honorable discharge, removing his "Inactive Status." Ironically, that means strings were pulled to get Bush out of the Guard in 1973, just as they were pulled to get him enrolled in 1968.
