Movies like these were typical of the time. You must put this movie in that context. Too many critics compare the old movies and their politics with today's views. Flight for Freedom like so many films in the 1940's had a purpose; to win the hearts and minds of the average American who may have had doubts about why we were fighting. Amelia Earhart was an icon of the American spirit and therefore, by demonizing the Japanese military who may or may not have killed her; the US government could whip up a frenzy of resolve to fight the war on to the finish. Ironically, espionage is a capital offense in most countries and it was typical to be awarded a long sentence or a possible death penalty. But it makes good drama, since the thought of killing a female for such a crime is yet another possible reason for FDR to get the US into the war.
