Yeager was commissioned a second lieutenant while at Leiston, and was promoted to captain before the end of his tour. He flew his 61st and final mission on January 15, 1945, and returned to the United States in early February 1945. As an evader, he received his choice of assignments and, because his new wife was pregnant, chose Wright Field to be near his home in West Virginia. His high number of flight hours and maintenance experience qualified him to become a functional test pilot of repaired aircraft, which brought him under the command of Colonel Albert Boyd, head of the Aeronautical Systems Flight Test Division.
