Hey GP,
I am doing some family research for a friend, and this particular subject includes her Great Uncle, Vernon Otis Elmore. He enlisted in 1942, and served until 1969. I believe that he may have retired in 1969 as a Colonel.
I found an index number for an aviation incident report online and it mentions him being in the USAAF:
ELMORE, VERNON OTIS O-434090
and that there was an aviation incident report filed while he was on Mather Field Class 42A class roster. Half of the family says he wasn't even in the military, and the other has stories of him in the military. Since you have the 1942-43 yearbook for Mather Airfield, I wanted to ask if you might look to see if he is in there.
Many thanks for your time and efforts,
Richard Martin
