Lucky Byrd; Loris Adams (daughter of Major Adams); Major Adams (Randolph Field Commander); Skeets (air cadet); Bob Stone (villain, introduction, Rocky Stone's brother)
Several people on the base claim to have seen "Rocky" Stone, who had been killed some time previous, and Lucky dismisses it. But when he sees the ghostly figure himself, he ties that together with a ghost ship he has also seen. When he brings that ship down, Rocky's brother is flying it, and he tells Major Adams and Rocky that Rocky had written him that Lucky was responsible. The pair quickly set Stone straight and all is forgiven.
