When World War II broke out, Iris Nigg Lundin of Champaign left her small town in Minnesota and joined hundreds of other women in the newly formed Marine Corps women's Reserve. She became one of the first four female navigation instructors.
Producer Denise La Grassa said that in her conversations with Lundin, she was impressed by the strength of this woman who left a secure life in Minnesota to join the ranks of the Marines, the toughest of the tough. "This was the first time many of these men who were her students had encountered a female instructor and she really held her own," said La Grassa. "When I listened to her stories, I was moved by her description of how she went to bat for African-Americans on the military bases where she worked. She was brave enough to tell a higher-ranking officer that he shouldn't be treating a steward in a demeaning manner. Later in her life, equality was very important to her."
