Disambiguation
NOT to be confused with 'flying saucers,' though the terms were used interchangeably in the 1940s-1950s. 'Flying discs' specifically became a common descriptor following Kenneth Arnold's 1947 sighting and was later superseded by the more neutral acronym 'UFO' (Unidentified Flying Object) and eventually 'UAP' (Unidentified Aerial Phenomena).

Flying Discs is a historical term used by the U.S. military, government officials, and media from 1947 onward to describe unidentified flying objects, particularly those appearing disc or saucer-shaped. The term emerged after pilot Kenneth Arnold's June 24, 1947 sighting near Mount Rainier, which sparked widespread public reports and a major media phenomenon. Flying Discs became the primary descriptive language used within Project Sign (1948-1949) and related government investigations into unidentified aerial phenomena. The terminology was later standardized under the acronym UFO by Captain Edward J. Ruppelt of the USAF, who sought more neutral language than 'flying saucer.' The term remained in official use through Project Blue Book (1952-1969) and represents a key linguistic artifact of early Cold War-era UAP investigation doctrine.

Flying Discs é um termo histórico utilizado pelas forças armadas dos EUA, autoridades governamentais e mídia a partir de 1947 para descrever objetos voadores não identificados, particularmente aqueles com aparência de disco ou pires. O termo surgiu após o avistamento do piloto Kenneth Arnold em 24 de junho de 1947 perto do Monte Rainier, que desencadeou relatos generalizados do público e um fenômeno mediático importante. Flying Discs tornou-se a linguagem descritiva primária utilizada no Projeto Sign (1948-1949) e investigações governamentais relacionadas de fenômenos aéreos não identificados. A terminologia foi posteriormente padronizada sob a sigla UFO pelo Capitão Edward J. Ruppelt da USAF, que buscava uma linguagem mais neutra do que 'flying saucer'. O termo permaneceu em uso oficial através do Projeto Blue Book (1952-1969) e representa um artefato linguístico chave da doutrina de investigação de UAP da era da Guerra Fria inicial.
