J. Allen Hynek
Astronomer; scientific consultant to U.S. Air Force Projects Sign, Grudge, and Blue Book (1948–1969)
Josef Allen Hynek (1910–1986) was a professor of astronomy at Ohio State University and later Northwestern University, and the scientific consultant retained by the U.S. Air Force from 1948 to 1969 to evaluate UAP reports collected under Projects Sign, Grudge, and Blue Book. [1]
Hynek began his work skeptical of the field, and was responsible during the 1950s for proposing prosaic explanations for many sightings — most controversially attributing the 1966 Dexter, Michigan case to 'swamp gas,' a phrase that became a public-relations problem for the Air Force. [2] By the late 1960s, however, Hynek had revised his position. His 1972 book The UFO Experience: A Scientific Inquiry formalized the Close Encounter classification — CE1 (visual), CE2 (physical effects), CE3 (occupants) — that remains the lay vocabulary for the field. [3]
After Project Blue Book closed in 1969, Hynek founded the Center for UFO Studies (CUFOS) in 1973 in Evanston, Illinois, with the explicit goal of conducting scientific evaluation of UAP reports outside the U.S. government chain. CUFOS holds the largest non-government UAP case-file archive in the United States and continues to publish a peer-reviewed journal. Hynek consulted on Steven Spielberg's 1977 film Close Encounters of the Third Kind, which takes its title from his classification scheme. [4]

Pentagon's AARO Moves to Contract Access to North America's Largest Private UAP Historical Records Collection
The Pentagon's All-domain Anomaly Resolution Office (AARO) has moved to issue a sole-source contract to the National Unidentified Flying Object Historic Records Center (NUFOHRC), a New Mexico-based nonprofit that holds what a Defense Department source described as the world's largest private collection of UAP-related historical records. Details of the planned commercial data subscription were first disclosed in a Defense Department contracting notice reported by DefenseScoop on September 2, 2026. The subscription would grant AARO digital access to NUFOHRC's proprietary data, metadata, and analytical products, with particular emphasis on materials predating 1990. The move represents AARO's latest step to fulfill congressional mandates requiring a comprehensive review of U.S. government UAP involvement dating back to 1945, as directed by the fiscal year 2023 National Defense Authorization Act. NUFOHRC, founded and led by UAP historian David Marler, holds hundreds of thousands of unique case files — including the complete archives of early civilian scientific UFO research groups and personal files of Dr. J. Allen Hynek, who worked on the Air Force's Project Blue Book. The proposed contract structure includes a one-year base period with four one-year option periods; the total estimated cost was not disclosed.

Radar tracks unidentified objects over Washington, D.C.
Across two consecutive weekends, multiple radar installations and visual observers track unidentified objects above the restricted airspace surrounding the U.S. Capitol and White House. The Air Force convenes its largest press conference since World War II to address the events.
