Looks are sometimes everything
It so happened that one of the escapers became my flight commander after the war. He seldom spoke of his experiences but did relate how he and a companion were subsequently caught after the escape. Interrogated by the Gestapo, he was returned to captivity and his companion was chosen to be shot. One was tall, fair, nordic and typically aryran in looks. His fellow escapee was sallow and swarthy in complexion and mediterranean in appearance. He honestly believed he survived because of the accident of genes.
