In attempting to arrive at conclusions as to the mture of uniden­ tified .flying object incidents in the United States, this Command ha.a me.de a study of approximately 180 such incidents . Data derived from initial re­ ports have been supplemented by .further information obtained from check lists submitted by mail, from interrogations of other field agencies, and by personal investigation by personnel of this Command in the case of in­ cidents that seem to indicate the possibility of obtaining particularly significant information. 2 check lists submitted by mail, from interrogations of other field agencies, and by personal investigation by personnel of this Command in the case of in­ cidents that seem to indicate the possibility of obtaining particularly significant information. 2. The objects described fall into the following general classifica­ tion groups, according to shape or physical configuration, a. Flat disc of circular or approximately o:l.rcular shape . b. Torpedo or cigar shaped aircraft, with no wings or fins visible in flight. c. Spherical or balloon shaped objects. d. Balls of light with no apparent form attached. 3. Some of the objects sighted have definitely been identified, upon further investigation, as weather or upper air scientific balloons of some type . A. great many of the round or balloon shaped objects indicated in paragraph 2c above are probably of the same nature, although in most cases, definite confirmation of that fact has been impossible to obtain. 4 . Some of the objects have been identified as beiilg astro - physical in nature . For example , in daylight sightings, the planet Venus has been reported as a round, silvery object at extremely high altitude . Action is being taken to obtain the services of a prominent astro-physicist as a oon• sultant, to study all of the incidents to determine l'lhether some can be identified as meteors, planets or other manifestations of astral bodies the services of a prominent astro-physicist as a oon• sultant, to study all of the incidents to determine l'lhether some can be identified as meteors, planets or other manifestations of astral bodies . s. Arrangements for accomplishing a study of the psychological problans involved in this project are being made in coordination with the Aero-Medical Laboratory at this Headquarters . The possibility that some of the sightings are halluoir:a tions, optical illusions or even deliberate hoaxes has been con- sidered. ~ 1/cf \ t:. ... b l Jo~-<..-' :>.t 2 T-73017 '• 1st Itld Basic ltr fr Hq USAF, 3 Nov 48 to CG, AMC, "Flying Object Incidents in tne United States~ s. Although explanation of many of the incidents can be obtained from the investigations described abOV'e, there remains a certain number of re­ ports for which no reasonable everyday explanation is available. So far, no physical evidence of 'the existence of the unidentified sightings has been obtained. Prominent scientists, including Dr. Irving Langmuir of the General Electric· Company, have been interviewed to determine whether they could advance any reasonable explanation for characteristics exhibited by In an early interview, Dr. Langmuir indicated that the objects sighted. these incidents could be expl&ined, but insufficient data were available at that time on whether they could advance any reasonable explanation for characteristics exhibited by In an early interview, Dr. Langmuir indicated that the objects sighted. these incidents could be expl&ined, but insufficient data were available at that time on which to base definite conclusions. It is planned to have another interview with Dr. Langmuir in the near future to review all the data now available, and it is hoped that he will be able to present some opinion as to the nature of many of the unidentified objects, particularly those described as "balls of light." 7 • All information that has been made available to this Headquarters indicates that the discs, the cigar shaped objects, and the "balls of light" are not of domestic origin. Engineering investigation indicates that disc or wingless aircraft could support themselves in fli1?11t by aerodynamic means. It is probable that the problems of stability and control could also be solved for such aircraft. However, according to current aerodynamic theory in this country, aircraft with such configurations would hl.ve relatively poor climb, altitude and range characteristics with power plants now in use. a. The possibility that the reported objects are vehicles from another planet has not been ignored. However, tangible evidence to support con­ clusions about such a possibility are completely lacking. The occurrence of inoidents ill relation to the approach to the earth of the planets Mercury, Venus and has not been ignored. However, tangible evidence to support con­ clusions about such a possibility are completely lacking. The occurrence of inoidents ill relation to the approach to the earth of the planets Mercury, Venus and Mars have been plotted. A periodic variation in the frequency of incidents, which appears to have some relation to 'the planet approach curves, is noted, but it may be purely a coincidence• 9. Reference is made to "The Books of Charles Fort" with an introduc­ tion. by Tiffany Thayer, published 1941, by Henry Holt & Co., New York, N. Y. It appears that simular phenomena have been noted and reported for the past century or more. 10. In view of the above, the following conclusions are drawn, a. In the majority of cases reported, observers have actually sighted son-, type of flying object which they cannot classify as en air­ craft within the limits of their personal experience. T-73017 Ba.sic ltr fr Hq USAF, 3 Nov 48 to CG, AMC, "Flying Object Incidents in the United States" 1st· Ind b. There is as yet no conclusive proof that unidentified flying objects, other than those which are known to be balloons, are real aircraft. c. Although it is obvious that some types of flying objects have been sighted, the exact nature of those objects cannot be that unidentified flying objects, other than those which are known to be balloons, are real aircraft. c. Although it is obvious that some types of flying objects have been sighted, the exact nature of those objects cannot be established witil physical evidence, such as that which would result from a crash, has been obtained. 11. It is not considered advisable to present to the press information on those objects which we cannot yet identify or about which we camiot pre­ sent any reasonable conclusions. In the event that they insist on som, kind ot a statement, it is suggested that they be informed that m.a:cy ot the objects sighted have been identified as weather balloons or astral bodies, and that investigation is being pursued to determine reasonable explanations tor the others . 12 . A report, summarizing the results obtained from analysis of the data and a technical investigation of the engineering aspects of -the objects described, is nearly complete, and a copy will be forwarded to your Head­ quarters in the near future .
