In a document dated May 2, 1973, Bush's immediate superiors gave him his annual performance review for the period from May 1, 1972, to April 30, 1973. The review stated that "Lt. Bush has not been observed at this unit during the period of the report." Lt. Col. William D. Harris Jr. and Lt. Col. Jerry B. Killian also wrote, "A civilian occupation made it necessary for him to move to Montgomery, Ala. He cleared this base on May 15, 1972, and has been performing equivalent training in a non-flying status with the 187 Tac Recon Gp. Dannelly ANG Base, Alabama."
