The story that Stanley Armour Dunham was involved in espionage at Boeing during WWII is just that, a story. If you will notice there is a Boeing tie to other members of his family including his own father. Stanley Armour Dunham signed up with the military in June 1942, so just exactly when was he involved in espionage? According to the “official” story Madelyn Dunham was employed at Boeing during the war years as a quality control worker.
Thanks for the clarification.
