Astronomer and Air Force consultant to Projects Sign, Grudge, and Blue Book. Originally a skeptic; later founded CUFOS and proposed the close-encounter classification system that still anchors the field.
J. Allen Hynek was a prominent astronomer who served as the primary scientific advisor to the United States Air Force UFO studies, including Project Blue Book. Initially a skeptic tasked with debunking sightings, he gradually realized that a core percentage of anomalous encounters defied conventional scientific explanation. Hynek's key contribution was the creation of the 'Close Encounters' classification system and his eventual founding of the Center for UFO Studies. He publicly rebuked the Air Force's dismissive approach to the phenomenon, arguing for rigorous, open scientific investigation devoid of military bias. His transition from government debunker to leading civilian scientific advocate is a foundational arc in UAP history.
