In his military memoirs, Don Westerfield Sr. shares an intimate look inside his experience of serving in the Indiana Air National Guard and the United States Air Force from 1950 to 1991. From an eager Midwestern teenager whose parents refused early enlistment to a grease monkey working on iconic planes, he ascended to the highest enlisted military rank of chief master sergeant. With humor and candor, "Echoes of Engines and Men: Memoirs of an Air Guardsman" chronicles the lessons he learned and taught, aircraft he worked on and flew in, and the people, places and adventures that filled his life as an airman, aviation mechanic and unit member of the 181st Tactical Fighter Group.
