CNN.com – Bush military file lacks required records – Sep 6, 2004

Bush was approved to train in September, October and November 1972 with the Alabama Air National Guard’s 187th Tactical Reconnaissance Group. The only record tying Bush to that unit is a dental exam at the group’s Montgomery base in January 1973. No records have been released giving Bush permission to train with the 187th after November 1972.
Walls, the Air Force combat veteran, was assigned to the 187th in 1972 and 1973 to train its pilots to fly the F-4 Phantom. Walls and more than a dozen other members of the 187th say they never saw Bush. One member of the unit, retired Lt. Col. John Calhoun, has said he remembers Bush showing up for training with the 187th.
