In the weeks after Kenneth Arnold's sighting of June 1947 set off a national wave of "flying disc" reports, Army Air Forces intelligence asked the FBI to help investigate. An FBI memo records that the officer in charge, Lieutenant Colonel George Garrett, privately suspected some of the objects might belong to a secret U.S. project.[1][2]
Garrett's study
Garrett worked for Brigadier General George Schulgen, chief of the Air Intelligence Requirements Division, who in July 1947 asked the FBI to help locate and question people who had reported discs. Garrett compiled a short study of the best early cases, later nicknamed the "mini estimate of the situation", drawing on 16 cases from about 22 June to 12 July 1947. FBI Special Agent S. W. Reynolds acted as liaison and investigated at least one case himself.[2][3]
The suspicion

In a memo summarising Reynolds's talks with the Air Force, the FBI recorded that Garrett and others suspected the objects might be a secret American project, in which case the Bureau's work would be wasted. According to researcher Kevin Randle, the group expected to be told to stop investigating; instead, General Nathan Twining wrote to Schulgen on 23 September 1947 that the phenomenon was "something real and not visionary or fictitious", recommending the classified study that became Project Sign.[1][2]
The FBI pulls out
The arrangement irritated J. Edgar Hoover, and by the end of September 1947 the FBI had withdrawn from disc investigations partly because it learned that its role was mainly to screen out hoaxes. Schulgen assured the FBI that the discs were not an Army or Navy project.[1][4]
Significance
The memo, from the FBI's flying disc file now public on the FBI's Vault website, shows that even the officers running the inquiry did not know what the discs were, and that a secret U.S. weapon was one of their leading theories alongside Soviet aircraft.[1][4]
