Just by looking at the page that you have offered I picked up the words " Flying Saucer Review Group" and its my impression that this was the same discussion group started by a lady by the name of Clara John. They were mainly military men, engineers, scientists interested in the " Flying Saucer problem" at the time. I attended one of the informal get togethers with my father at the time and not much longer after that he established what he called NICAP.
Can anyone else give me more information on what this little piece tells you? Linda
