Gray Rinehart may be the only person to have commanded an Air Force unit, written speeches for Presidential appointees, and had music on "The Dr. Demento Show."
Gray's fiction has appeared in Analog Science Fiction & Fact, Asimov's Science Fiction, Orson Scott Card's Intergalactic Medicine Show, and elsewhere. He is also a singer/songwriter with one album of mostly science-fiction-and-fantasy-inspired songs -- Truths and Lies and Make-Believe -- and another album in work.
Before becoming a Contributing Editor (the "Slushmaster General") for Baen Books, Gray fought rocket propellant fires, refurbished space launch facilities, commanded the Air Force's largest satellite tracking station, and did other interesting things during his rather odd US Air Force career. Gray's alter ego is the Gray Man, one of several famed ghosts of South Carolina's Grand Strand, and his web site is http://www.graymanwrites.com.
