Sky King, for those of you born after about 1958, was a tv series about a pilot on the Flying King Ranch in Texas, He had a neice named Penny, and an airplane called the Song Bird. He was Superman without a cape. He was probably the first person I ever heard say "over and out" because he talked on a radio in his plane. (Brodrick Crawford was probably the second in "Stories of the Highway Patrol" sometime later.)
That being said, once again, over and out.
