Earl, I do not know. Due to the Air Force sending me to Germany only 1-1/2 years after I met Frank, I did not get to spend as much time with him as I would have liked. He died in January 1980 only 2 months after I came back from Germany. His two sons were fighter pilots in WWII and commercial airline pilots after their military careers. I never met either of them, they lived outside of Colorado. Frank's wife had died while I was in Germany, so I was not able to get in touch with any of the family. His wife did tell me one time that Frank did not keep a lot of stuff as they had moved from a house to a small apartment.
