UAP Activity in the United States (1945–1975): A Resource-Constrained, Coherent Single-Operant Pattern Centered on Atomic Facilities

To the point

Ian M. Porritt, Larry J. Hancock, and Sean Grosvenor conclude that UAP activity across the continental United States from 1945 to 1975 came from a single, limited‑resources reconnaissance group, with intermittent nocturnal sightings around atomic facilities and no evidence of simultaneous multi‑site operations, indicating coordinated intelligence by one actor and the need for ongoing monitoring.
