When, however, on Monday, January 16,a science fiction film about visitors from outer space was shown on television, there was an immediate increase in reports of sightings fromall parts of the States. The commanding officer, Wayne Tyler, who was directly responsible for the study of all such reports, decided to make his findings known.
