The incident came to be called the "Hill Abduction" and the "Zeta Reticuli Incident" because two ufologists connected the star map shown to Betty Hill with the Zeta Reticuli system. Their story was adapted into the best-selling 1966 book The Interrupted Journey and NBC's 1975 television film The UFO Incident.
