Disambiguation: Refers to the formal U.S. institutional framework for collecting and investigating UFO/UAP reports. Primary manifestation: Project Blue Book (1952–1969). Not to be confused with informal sighting reports or media coverage; this is the official government operational infrastructure.

Unidentified Flying Objects Reporting was the formal U.S. government system for standardized collection, investigation, and analysis of UFO reports, primarily administered by the United States Air Force from 1947 to 1969. The most prominent institutional expression was Project Blue Book (1952–1969), which operated under the direction of the Air Force Technical Intelligence Center and investigated 12,618 reported sightings, determining that 701 remained unexplained despite analysis. Under leadership including Captain Edward J. Ruppelt, the program implemented standardized witness questionnaires and commissioned statistical analysis by the Battelle Memorial Institute. The program was terminated on December 17, 1969, after the Air Force concluded that investigated UFOs posed no threat to national security. All records were transferred to the National Archives and remain available for public examination.

Unidentified Flying Objects Reporting foi o sistema formal do governo dos EUA para coleta padronizada, investigação e análise de relatos de OVNIs, administrado principalmente pela Força Aérea dos EUA de 1947 a 1969. A manifestação institucional mais proeminente foi o Projeto Livro Azul (Project Blue Book, 1952–1969), que operava sob a direção do Centro de Inteligência Técnica da Força Aérea e investigou 12.618 relatos de avistamentos, determinando que 701 permaneceram inexplicados apesar da análise. Sob a liderança de oficiais como o Capitão Edward J. Ruppelt, o programa implementou questionários padronizados para testemunhas e encomendou análise estatística do Instituto Battelle Memorial. O programa foi encerrado em 17 de dezembro de 1969, após a Força Aérea concluir que os OVNIs investigados não representavam ameaça à segurança nacional. Todos os registros foram transferidos para os Arquivos Nacionais e continuam disponíveis para exame público.
