On the website shadolibrary.org, Deborah Rorabaugh creates a timeline of events chronologically using a few known dates and facts. For example, Exposed should come before all other episodes featuring Paul Foster, and there are a few definitive dates given (two newspaper dates, a death and script date) so with other clues, it is possible to form a good correlation UFO Episode Timing.A number of episodes were edited together in the early 1970s to form the feature-length compilation films Kill Straker, a Question of Priorities (1973; formed, in order of appearance, by "Confetti Check A-Ok", "Flight Path" and "A Question of Priorities") and Invasion: UFO (1974; mainly formed by "Identified", "Computer Affair", "Reflections in the Water", with ending from "The Man Who Came Back" and segments from "E.S.P." and "Confetti Check A-Ok" used to bridge continuity gaps).
