I am also looking for photos anything associated with Southern Airways. I was a survivor of Southern 242 on 4 April 77 (MSL - HSV to ATL on DC-9-32 N1334U) and I am doing research on the accident as well as on the history of Southern. I have a small website started at:
Perhaps I can assist you in what you are looking for. I would love to
interiew your father about his time at Southern.
I currently live near Dulles airport. Although I was not an airline employee at the time of the accident, I currently work as an FA for United Express.
I look forward to hearing from you or anyone else who wants to share info on Southern.
