Top-Secret 1949 Document

by Jan Aldrich

In the general correspondence file on UFOs for the Director of Intelligence (Decimal files .009 "Flying Disks" 1949), there were vague references made to this document and other USAF contacts with the Joint Intelligence Committee regarding UFOs. Citizens Against UFO Secrecy (CAUS) did submit FOIA requests for the document, which was thought to be classified secret.

CAUS had been looking for this document for more than 20 years. It was found in the National Archives II in College Park, Maryland, in the USAF Air Force Director of Intelligence files entitled A General File July 1945--December 1954: Records Relating to the Requirements for and the Collection and Dissemination of Intelligence" (Records Group 341, Entry 214A) during research for Project 1947 in July 1997. The JIC document had not been found previously because it had been classified top secret and was not in the records checked to satisfy the previous FOIA requests. This discovery demonstrates the usefulness of on site records inspection by researchers. 

Project Saucer

In his 1950 paperback book The Flying Saucers Are Real, pp. 18 &19, Donald E. Keyhoe reported a conversation with Ken Purdy, an editor at True magazine: 
"Have you seen the [Saturday Evening] Post this week?" [said Purdy.] 
I told him no.
"There’s something damned queer going on. For fifteen months, 'Project Sauce' is buttoned up tight. Top Secret. Then suddenly, Forrestal gets the Saturday Evening Post to run two articles, brushing the whole thing off. The first piece hits the stands and what happens?" 

Purdy swung around, jabbed his finger at a document on his desk. 

"The same day, the Air Force rushes out his Project 'Saucer' report. It admits they haven’t identified the disks in any important cases. They say it’s still serious enough--wait a minute"--he thumbed through the stapled papers--"to require constant vigilance by 'Project Saucer' personnel and civilian population."

Purdy only knew the half of it. There was more. Had Keyhoe or Purdy known of the other activities around the last part of April and early May, they would have been sure there was something funny occurring. The Air Force made a concerted effort to disseminate its position to both official circles and the public.

 Among these activities were: 

1. The Directorate of Intelligence personnel briefed the USAF Deputy Chief of Staff for Operations and his staff on UFOs on April 27, 1949. (Directorate of Intelligence, USAF, Decimal Correspondence File, "Flying Discs," 1949, National Archives II, College Park, Maryland.) 

2. The Air Force sent a top-secret "Unidentified Aerial Objects" presentation with Appendix A, a summary of Air Force actions, to the Joint Intelligence Committee 

(JIC) on April 27, 1949. The Committee was composed of representatives from the Army, Navy, Air Force, State Department, FBI and CIA. (Deputy Director of Intelligence, USAF. Records Group 341, Entry 214A, Top Secret Control #2-7051-A, National Archives II, College Park, Maryland. Reprinted in full at the end of this article.) 

3.The USAF printed copies of the Top Secret "Analysis of Flying Object Incidents in the United States" (Air Intelligence Report 100-203-79) by the USAF Director Intelligence and the Office of Naval Intelligence. The printed report cover shows the date, April 28, 1949, although the document had been approved on December 1948. (USAF Directorate of Intelligence, Current Intelligence Files: Top Secret Control #2-7341,  National Archives II, College Park, Maryland; see  

4. The "Memorandum for the Press: Project Saucer" was released on April 29, 1949. ("Project Saucer," Memorandum to the Press # M26-49, April 27, 1949, Project Blue Book files; see

5. The Saturday Evening Post hit the newsstands on April 29,1949, with the first part of Sidney Shalett’s article on UFOs. ("What You Can Believe About Flying Saucers," Saturday Evening Post, April 30, 1949, pp. 20-21, 136-39; part 2, May 7, 1949, pp. 36, 184-86.) 

The Air Force Public Relations Office cooperated fully with Shalett in the preparation of his article, but Major General Cabell had major problems. He would rather have had complete control over the press policy. However, his attempt to obtain this authority from Secretary of Defense Forrestal appeared to have been thwarted by Mr. Leo of the Public Relations Office. (See the Air Staff Study on press policy and flying discs, http://www/ ; Memorandum to Forrestal on press policy, ;

Memorandum for Record concerning press policy, ;

and Secretary of Air Force Office of Information UFO files 1947-1952, microfilm #33765, USAF Historical Research Activity, Maxwell Air Force Base, Ala.) 

Shalett’s article dismissed UFOs as any type of problem despite the conclusions of the recently printed "Analysis of Flying Object Incidents in the United States," which recommended that efforts be taken to determine whether UFOs represented a domestic development. Or if not, that actions be taken to determine whether they were a foreign development. 

Shalett’s article was his own, but it was probably endorsed by Leo. The Project Saucer press release was less negative, as Purdy pointed out to Keyhoe. There was then a necessity to make sure that the USAF and the intelligence community knew the Directorate of Intelligence’s position. Therefore, the briefings prior to the release of the Project Saucer press memorandum informed these officials of the Air Force intelligence position. 

Project Grudge’s files had been opened to Shalett. Leo wrote to Wright Field, advising that Shalett should be given access to all information except for foreign sources and any material classified top secret. 

Soon after Shalett’s article hit the stands, other writers and editors also requested access to the files at Wright Field. Purdy was one of the first. Maj. Gen. Cabell may have ost his bid to limit press access, but when asked about these new requests, Cabell responded that if one writer was given access, then all of them should have access. Cabell’s sense of fair play may have helped Keyhoe and Purdy obtain the information that convinced them that UFOs were extraterrestrial. The desired effect of Shalett’s article was soon overcome by Keyhoe’s articles and his subsequent bestselling book, The Flying Saucers Are Real

The JIC document has eluded researchers for years. In it one can see the seeds of the later Project Grudge report. It contains a summarized history of the Air Force’s early attempt to investigate UFO reports. 

There is one error in the document. The study that led to "Analysis of Flying Object Reports in the United States" was initiated by Maj. Gen. Cabell on July 27, 1948, shortly after the Chiles-Whitted sighting, not August 6, 1948, as given in the JIC presentation. (Records Group 341, General Files, Entry 214, Top Secret Control # 2-3931.) 

In the JIC report the Directorate of Intelligence had already abandoned a major portion of the freshly printed A Analysis." In about 18 months the "Analysis" would be completely discarded and ordered destroyed. (Letter, Subject: Destruction of Air Intelligence Report Number 10079, September 25, 1950, Directorate of Intelligence, USAF, Decimal Correspondence File, A Flying Discs," 1950, National Archives II, College Park Maryland.) 

Report by the Director of Intelligence, USAF, to the
Joint Intelligence Committee on
Unidentified Aerial Objects

The problem

1. To advise the Joint Intelligence Committee of the findings of the Directorate of Intelligence, USAF, regarding the sightings of unidentified aerial objects and the Air Force organization established for further investigation and solution of the problem. 

Facts bearing on the problem

2. Following the great number of reported sightings of flying discs during the summer of 1947, Hq, Air Materiel Command, in a letter dated 23 September 1947, requested that the Commanding General, Army Air Forces, issue a directive assigning a priority, security classification and code name for a detailed study of flying disc reports. Hq, Air Materiel Command explained that their action was based on the opinion that phenomena reported appeared to be real and that there were objects in existence which would approximate the shape of a disc. AMC concluded that some incidents might be caused by natural phenomena but that some incidents described characteristics which suggested evasive tactics. Awaiting a specific directive, Hq, AMC continued to collect information on flying disc incidents in order to more clearly define the nature of the phenomena. On the 22nd of December 1947, in a memorandum, "Analysis of Flying Disc Reports," the Director of Intelligence concurred with Air Materiel Command’s recommendation and forwarded their letter to the Director of Research and Development, DCS/M for reply. 

3. In a letter dated 30 December 1947, the Director of Research and Development, DCS/M, advised the Commanding General, AMC, that Air Force policy was not to ignore reports of sightings and phenomena in the atmosphere but to recognize that part of its mission to collect, evaluate and act on information of this nature. To implement this policy it was directed that Hq, Air Materiel Command set up a project with the purpose of collecting, collating, evaluating, and distributing to interested government agencies and contractors, all information concerning sightings and phenomena in the atmosphere which could be construed to be of concern to the national security. This directive assigned a priority of 2-A to the project, a RESTRICTED classification, and a code name of "SIGN." 

4. At Air Materiel Command the Technical Intelligence Division was assigned the responsibility for accomplishing this mission with the full assistance of all divisions and activities within Air Materiel Command to permit successful completion of the project. The cooperation of the Army, Navy, Coast Guard and F.B.I. was solicited in order to facilitate the forwarding and investigation of all reports. Arrangements were effected for handling such reports directly with Air Materiel Command. 

5. In addition to the collection, analysis and investigation activities directed by the project personnel at Hq, Air Materiel Command, Air Intelligence Memorandum dated 6 August 1948, subject: "Flying Saucers," required that a study be made by the Air Intelligence Division to examine the pattern of tactics of reported flying saucers and develop conclusions as to their probability. The results of this analysis were prepared as Air Intelligence division (DI/USAF-ONI) Study No. 203, "Analysis of Flying Object Incidents in the United States." The Directorate of Intelligence has maintained close liaison with Project "SIGN" activities in order that appropriate staff sections of Headquarters, USAF may be adequately advised on the entire subject of unidentified aerial phenomena reports. 

6. The code name of "SIGN" for the project was changed to "GRUDGE" by a request on 16 December 1948 by the Director of Research and Development, DCS/M, Hq, USAF. "GRUDGE" under the U.S. Joint Services Code Word Index refers to the title "Detailed Study of Flying Discs." 

Assumptions and conclusions

7. Hq, Air Materiel Command will continue its investigations under project "GRUDGE" and the Directorate of Intelligence, USAF, will maintain close liaison with that Command in order to advise Staff sections on the subject of unidentified aerial objects. 

8. See Appendix "A" for discussion of the problem and conclusions drawn therefrom. 


9. It is recommended that the Joint Intelligence Committee: 
a. Furnish the Director of Intelligence, USAF, with comments on this paper.

Appendix A

Unidentified Aerial Objects
Facts and Discussion
1. As of 10 March 1949, a total of 256 incidents involving unidentified aerial objects had been recorded, under Project "SIGN." The majority of these were domestic observations but there were many from reports from foreign sources. In each incident the observers have been interrogated by investigators and the results have been analyzed by technical personnel.

2. Condensed summaries have been prepared on each incident to provide basic information to individuals and agencies having a responsibility or interest in the project. 

3. The extreme lack of accurate observed details and the unpredictable occurrence of incidents have made positive identification extremely difficult. Data on unidentified aerial objects has grouped the incidents as follows: 

13.3% - discs 

43.0% - spherical or elliptical [sic] shape (including balls of fire) 

6.0% - cylindrical shape 

2.5% - winged objects 

32.2% - shapes other than those above

4. In order to identify ordinary and conventional objects, that have probably been included in the list of reported incidents, graphical methods have been applied as follows: 

5. Prepared graphical data includes: 

a. Charts concerning unidentified aerial objects, to indicate: 
(1) Type of object observed 

(2) Vicinity in which particular type of object was observed 

(3) Direction of flight

b. Location of guided missiles, research and related centers
c. Location of airlines, airfields, both military and commercial 

d. Locations of radio beacon stations 

e. Known or projected radar stations from which reports and assistance may be derived 

f. Meteorological stations from which balloon release data, radiosonde or theodolite readings may be obtained 

g. Past, current, and projected celestial phenomena 

h. Flight paths of migratory birds

6. A psychological analysis of the reported data is being prepared by Aero-Medical Laboratory, AMC, for the purpose of determining those incidents that are probably based upon errors of the human mind and senses. A preliminary verbal report from the professional psychologists indicates that a considerable number of incidents can be explained as ordinary occurrences that have been misrepresented, as the result of human errors. 

7. Specialist services, supplementary to those of AMC technical offices, are being provided by a number of agencies. 

8. The Air Weather Service has reviewed incident data and has provided the information that 24 of the first 172 coincide, both with respect to location and time, with the release of weather balloons. 

9. The Ohio State University has contracted with AMC to supply astronomical services in an effort to identify meteors, planetoids and associated phenomena. Professor Hynek, Ohio State University Astrophysicist and head of the University Observatory has reviewed the incident summary sheets. 

10. Preliminary report of Dr. Hynek, indicates that 30 per cent of the first 200 incidents are positively attributable to astronomical phenomena, and 45 per cent could be explained on the basis of such phenomena or the sighting of weather balloons and other objects. This gives a total of 75 per cent of all incidents with possible explanation. 

11. Members of the Scientific Advisory Board o the Chief of Staff, USAF, who have provided consultant services to Project "Grudge," include Dr. Irving Langmuir, Chief, General Electric Research and Dr. G. E. Valley of MIT. 

12. Dr.G. E. Valley has displayed an active interest in Project "Grudge" to the extent of reviewing the reported incidents and writing an overall type of analysis in which he groups the various objects and then analyzes each group from the standpoint of scientific feasibility. 

13. Inasmuch as various surmises have been advanced that some of the reported observations may have represented "space ships" or satellite vehicles, a special study has been initiated with the Rand Corporation, under the Rand Project, to provide an analysis from this standpoint and also to provide fundamental information, pertaining to the basic design and performance characteristics that might distinguish a possible "space ship." Rand Corporation has also informed AMC that their analysis of all incidents leads them to the conclusion that there is nothing in any reported incidents which would go against a rational explanation. 

14. The Weather Bureau Library of the Department of Commerce has supplied information on "ball lightning." This was requested because of the belief by some persons that some of the observations may have represented "ball lightning." It appears that the subject of "ball lightning" occupies an undetermined status and authorities are not at all convinced that such a phenomenon actually exists. 

15. On 8 April 1949 the repeated occurrence of green fireball phenomena in New Mexico was discussed with Dr. Joseph Kaplan, member of the USAF Scientific Advisory Board. This phenomenon has caused considerable concern on the part of Hq, Fourth Army and has occupied the interests of Dr. Lincoln LaPaz of the University of New Mexico. Dr. LaPaz believes that the phenomena are not meteorites. Because of Dr. LaPaz’ outstanding ability for accurate observation and his experience in identification of meteoritic phenomena, Dr. Kaplan expressed the belief that the green fireball phenomena should be further investigated. Dr. Kaplan’s views and this phenomena were discussed 12 April 1948 with Dr. Theodore von Karman, Chairman, USAF Scientific Advisory Board, who feels that the problem is more properly in the field of upper atmosphere research than the field of intelligence. 

16. A summary of the incidents reported would indicate that: 

a. All incidents which coincide with explainable aerial activities or recorded natural phenomena should be eliminated from further consideration.

b. Creditable unexplained incidents involving light phenomena should be further investigated and analyzed by highly competent scientists who can establish the identity either within or without the limits of known natural phenomena. 

c. Creditable unexplained incidents which might involve the use of atomic powered craft of usual [sic] design should be considered jointly by the Atomic Energy Commission and highly competent aerodynamicists to determine the necessity for further consideration of such incidents by the National Defense Intelligence Agencies.


17. The majority of reported incidents are reliable to the extent that they have involved the sighting of some object or light phenomenon. 

18. In spite of the lack of accurate data provided by witnesses, the majority of reported incidnts have been caused by misidentification of weather balloons, high altitude balloons with lights and/or electronic equipment, meteors, bolides, and the planet Venus. 

19. There are numerous reports from reliable and competent observers for which a conclusive explanation has not been made. Some of these involve descriptions which would place them in the category of new manifestations of probable natural phenomena but others involve configurations and described performance which might conceivably represent an advanced aerodynamical development. A few unexplained incidents surpass these limits of credibility. 

20. It is unlikely that a foreign power would expose a superior aerial weapon by a prolonged ineffectual penetration of the United States.
