Philip Imbrogno

Philip J. Imbrogno is most relevant to the UAP record through his work on the Hudson Valley sighting wave of the 1980s. As a co-author of Night Siege with J. Allen Hynek and Bob Pratt, he helped turn numerous reports from New York and Connecticut into a widely discussed case history.
In the chronology, his significance is not as an official witness but as a local investigator and author whose books and case collections shaped public discussion of large, slow-moving triangular or boomerang-shaped objects in the northeastern United States.
