Stewart did not leave the military and continued to serve until May 1968 when he retired after 27 years of service during which time he was a bomber pilot during the Vietnam War.
Stewart played George Bailey in the classic movie and channeled his anger and guilt into the scenes where he rages at his family.
Stewart was haunted by 'a thousand black memories' from his time as an Air Force commanding officer that he took with him back to Hollywood after the war.

Stewart wrestled with the guilt of killing civilians in bomb raids over France and Germany including one instance where they destroyed the wrong city by mistake.
