This Federal Bureau of Investigation file section (62-HQ-83894, Section 4) collects 1947 to 1949 correspondence on flying discs. It includes Portland police officers' accounts of a silvery object over the city on September 11, 1947, an Alaska pilot's July 1947 sighting near Bethel, citizen letters answered by J. Edgar Hoover, and a 1948 Air Defense Command directive on disc investigations. The FBI replied that it was conducting no flying disc investigations. Later items concern William Albert Rhodes's disc photographs and a Los Angeles letter judged a probable prank.
From the source:Release of 2026-05-08 Incident: N/A, N/A. The FBI's 62-HQ-83894 case file includes investigative records, eyewitness testimonies, and public reports concerning Unidentified Flying Objects and flying discs documented between June 1947 and July 1968. The records include high-profile incident accounts, photographic evidence from sites like Oak Ridge, TN, and technical proposals regarding potential propulsion systems. Additional topics include convention programs, researcher accounts, and extensive media coverage from the period. This file is partially posted on FBI vault with more redactions and some pages missing. Included here is the complete case file with several newly declassified pages and only minor redactions.

/ been any piece of one recovered from any source whatever in order that ~tical study of its nature could be nade. Insofar as was known to him, the o~ actual 1fA~er1f,l which would be of~ value in determining its nature ere telephoto :f.ho!!phs which are now in the possession of engineers at Wright Field, Dayton, Ohi How detailed and how clear these photographs are, he was unable to state. Hes ted that one report has been reoeived concerning a collision o:f these missiles with another type of aircraft. This report, according to him, took place a ehort time prior to the report of numerous discs overr the United States, and the report 8l1Bllated from Czeohoslovalda. This report was th.at a Czecho slovakian transport had collided with some unidentified missile while in mid-air over the ocean, and that said missile and said transport bad been complete~ disintegrated vith.out recovery of parts or eurvivors tram eith.er. It was the belief of Colonel GASSER that this undescribed missile was perhaps the same tY'Pe of thing as the f~ng saucer~ Another :factor of' notice, accord.ins to Colonel GASSm, and as is portrayed by the photographs, it would appear that the missiles oan be maintained at a certain altitude above the contour of the ground. This could be done by, means of acme t1"P9 of radio altimeter or radio control. Natu rally, the path of the missile is not in emct parallel to the contour, as its purported great speed would create considerable lag in its flight. Another factor which is wor~ of note, according to Colonel GASSER, is that it is normally reported as beins seen at tremendouelJ' hish altitudes and al.ways travel ing in a straight line. He stated that he himself observed, on one occasion, a single vapor trail coming fran sane type of aircraft at unbelievabl.7 high altitudes, vhioh vapor trail extended tran horizon to horizon in a perfectly straight line. He observed the vapor trail while it was in the process of :formation and states that it vae ccmplete~ unlike ~ vapor trail he had ever observed before 1n all of his experienoe vith the air foroe. It was his judgment that whatever creat ed the vapor trail vas traveliDS at an unbelievably tremendous speed. This, together with reports that when close to the ground,the missile travels at speeds which make possible visual observation of its actions, would refl.ect that there is sane ability to control the speed of these missiles as well as the altitude. ( colonel GASSER concl.uded that this matter, whil.e still purely a matter of gueeevork, is nevertheless a source of great concern to the military establ.ish :ment of this country. Great efforts have been expended by the service to determine Just what the nature of these missil.es might be and, upon so determinins, deci d.e whether or not an adequate defense can be establ.ished. He also stated that it has given impetus to the research being done by the air farce in their own pro- gram of nuclear mert53 for the propulsion of aircraft to devel.op guided missil.es ) He also advised that insofar as was known to him, there was absolutely no con nection betwem these missiles and the fact that they vere observed close to Oak Ridge, Tennessee. He stated that this vas perhaps, and probably, a mtter of coincidence and they were seen in this area merely as they vere seen in forty six of the forty-eight states of the United States during the Month of July when so~ reports were being received. Thie inforr.ration is being submitted to the Bureau for whatever val.ue it may be, and no further action 1n the nntter is beina contemplated by this office, unless advised to the contrary.
