Philadelphia: Penn Publishing Company, (1937). Hardcover first edition - One of two stand-alone aviation books written by Wirt under her own name. Wirt went on to become a pilot herself. In writing about her career she commented that in the aviation stories perhaps she could detect "a long-slumbering personal wish? Until this moment, the motivation which led me, late in life, to become a pilot had gone unrecognized. At an age when wiser persons welcome Social Security, this misguided author took up flying, earned advanced ratings, and presently functions as a commercial pilot, reporter, and aviation columnist for a Toledo newspaper. Significantly, now that I might be better qualified to write aviation fiction, I feel no urge to do so." Illustrated by Frank Lea. Glossy frontispiece. 217 pp.
