Air Force Letter 200-5: UFO Reporting Directive Issued

Directive Overview Air Force Letter 200-5, issued on April 29, 1952, by Secretary Thomas K. Finletter, fundamentally transformed UFO reporting within the United States Air Force. The directive established that intelligence officers at every Air Force base must immediately report unidentified flying object sightings to the Air Technical Intelligence Center (ATIC) and all major USAF commands.

Operational Authority The letter granted Project Blue Book unprecedented authority to communicate directly with any Air Force installation without navigating standard chain-of-command procedures. This exceptional delegation of power significantly enhanced the project's operational efficiency and prestige within military hierarchies.

Reporting Procedures The directive mandated wire transmission of initial UFO reports to ATIC, with comprehensive details following via airmail. This two-tiered system ensured rapid notification while allowing thorough documentation of incidents.

Historical Significance The issuance of AFL 200-5 legitimized UFO investigation as an official Air Force priority, transforming the subject from an informal concern into a formal military responsibility. The directive remained effective until October 29, 1953, when it was subsequently modified by AFR 200-2.
