George W. Bush is Commissioned into the Texas Air National Guard

In May 1968, Bush was commissioned into the Texas Air National Guard.

After two years of active-duty service while training, he was assigned to Houston, flying Convair F-102s out of Ellington Air Force Base. Critics, including former Democratic National Committee Chairman Terry McAuliffe and Russ Baker, have alleged that Bush was favorably treated due to his father's political standing, citing his selection as a pilot despite his low pilot aptitude test scores and his irregular attendance. In June 2005, the United States Department of Defense released all the records of Bush's Texas Air National Guard service, which remain in its official archives.
In late 1972 and early 1973, he drilled with the Alabama Air National Guard, having moved to Montgomery, Alabama to work on the unsuccessful U.S. Senate campaign of Republican Winton M. Blount. In October 1973

Bush enlisted in the Texas Air National Guard on May 27, 1968 during the Vietnam War, with a commitment to serve until May 26, 1974. In his 1968 Statement of Intent (undated), he wrote, "I have applied for pilot training with the goal of making flying a lifetime pursuit and I believe I can best accomplish this to my own satisfaction by serving as a member of the Air National Guard as long as possible." He performed Guard duty as an F-102 pilot through April 1972, logging a total of 336 flight hours [1] and was twice promoted during his service, first to second lieutenant and then to first lieutenant.

In November 1970, Lt. Col. Jerry B. Killian, the commander of the Texas Air National Guard, recommended that Bush be promoted to first Lieutenant, calling him "a dynamic outstanding young officer" who stood out as "a top notch fighter interceptor pilot." He said that "Lt. Bush's skills far exceed his contemporaries," and that "he is a natural leader whom his contemporaries look to for leadership. Lt. Bush is also a good follower with outstanding disciplinary traits and an impeccable military bearing."
