Yeager named his plane after his wife, Glennis, as a good-luck charm: "You're my good-luck charm, hon. Any airplane I name after you always brings me home." Yeager and Glennis moved to Grass Valley, California, after his retirement from the Air Force in 1975. The couple prospered because of Yeager's best-selling autobiography, speaking engagements, and commercial ventures. Glennis Yeager died of ovarian cancer in 1990. They had four children (Susan, Don, Mickey, and Sharon). Yeager's son Mickey (Michael) died unexpectedly in Oregon, on March 26, 2011.
