Information was received today from Frank's son that Frank is gravely ill. There are a lot of you old timers out there that will remember Frank as I do. Frank was a friend of "SOSUS" and spent most of his adult life supporting the program. My thoughts and prayers are with Frank and his family at this very difficult time.

I will keep you informed. A very sad messenger, Ed Smock

Sad news indeed. Frank truly did so much to support the system's development. Have many fond memories of traveling with Frank and other AT&T engineers during some SP and system upgrade developments. Wishing him all the best as he fights his illness.
