Fran Ridge:

This is a 54-page comprehensive and qualitative effort and it will take many months, if not years, to get active links to cases all in place. Sixty additional case links were added on July 7. With the help of William Wise (Project Blue Book Archive), and Dan Wilson (digging out the cases from my checklist), the task was much easier. But without Brad Sparks' Comprehensive Catalog of Project Blue Book Unknowns, the entire project would have been impossible. Sparks also provided several historic entries. And our thanks go to Jean Waskiewicz who created the online NICAP DBase (NSID) that helped make it possible to link from the cases to the reports themselves. Others who provided information are also noted with their contributions. (Items on the Chop clearance list are coded "CCL"). But none of this would be complete without the story behind the wave of 1952, as told by none other than Richard Hall.

On March 2, 1950, a Joint Chiefs of Staff (JCS) meeting focused on establishing goals for a minimum air defense by 1952. The followoing month at a USAF Commanders Conference at Ramey AFB, Puerto Rico,  planners familiarized commanders with the thinking behind the plan of minimum defense as welll as with its contents. Referred to as the Blue Book Plan, it stipulated that a minimum air defense could be in place by mid-1952. It was estimated that July 1, 1952, as the critical date when the Soviets would pose a dangerous threat. General Charles Cabell expected the Soviets to have between 45 and 90 atom bombs and 70 to 135 Tu-4 bombers (copied B-29s) by that time. Was there a nuclear connection between this threat and the massive UFO sighting wave of 1952 and the events over Washington in July?

Richard Hall:
The summer 1952 UFO sighting wave was one of the largest of all time, and arguably the most significant of all time in terms of the credible reports and hardcore scientific data obtained. Electromagnetic (EM) effects and physical trace evidence were  more prominent in other waves, but 1952 (and 1953) featured recurring radar detection of UFOs, often from both ground and airborne radar, visual sightings by jet interceptor pilots sent up to pursue the mysterious objects, and cat-and-mouse chases in which the UFOs seemed to toy with the interceptors. Further, Air Force investigators who plotted the sightings noticed that they were concentrated around strategic military bases, and this clearly posed a threat to national security since their origin was unknown. Senior generals in the Air Force concluded that UFOs  were interplanetary in origin, and broadly hinted this belief in LIFE magazine for April 1952.


The 1952 UFO Sighting Chronology                                                                                                 



1952; London, Ont., Canada
Astronomer observed elliptical UFO with 2 bright body lights. [UFOE, VI]

Jan. 1952; Weston, Wyoming (BBU)
10:30 p.m. 38-year­old rancher saw a "shooting star" suddenly stop in mid-air between him and a mountain, spinning clockwise, with one red window periodically facing the observer, went down toward the Little Powder River, come up again. He turned his car to send light signals, object seemed to respond by stopping its red window to face witness. Spinning resumed, object rose and came down. Similar object arrived, then both went into the deep valley out of sight. (Vallée Magonia 88)

Brig. Gen. William M. Garland, Assistant for the Production of Intelligence, wrote a memorandum for General Samford with the title (SECRET) "Contemplated Action to Determine the Nature and Origin of the Phenomena Connected with the Reports of Unusual Flying Objects." (Courtesy, Joel Carpenter)

Jan. 9, 1952; Kerrville, Texas
Cat 3. Odd "roaring" interference on radio as UFO circled town.

Jan. 16, 1952; Artesia, New Mexico (BBU 1037)
A motionless dull-white, round object 5/3 larger than balloon.

Jan. 20, 1952; Fairchild AFB, Wash. (BBU)
Two Air Force master sergeants, intelligence specialists, reported a bluish-white spherical object with a long blue tail that flew beneath a solid overcast.

Jan. 21, 1952; Mitchel AFB, N.Y.
A Navy TBM torpedo bomber pilot chased a dome-shaped circular white object that accelerated and pulled away from him.

Jan. 22, 1952; Nenana, Alaska (BBU)
12:20 am.(AHST) Ground radar outpost and three airborne radar sets on F-94 interceptors tracked a distinct unexplainable target. USAF Lt. A. L. B. a CPS-6B radar operator at ADC radar site F-2, Murphy Dome AFS (about 19 miles WNW of Fairbanks), Alaska, tracked an inbound or outbound target at 210° azimuth at about 1,500 to 2,400 mph, and after 10-12 radar sweeps 12 secs each, urgently called twice (at 12:25 and 12:26 a.m.) for interception, and 2 USAF F-94 jets were scrambled [possibly multiple reversals of UFO direction in this time interval]. At 12:52-53 a.m., unidentified target was tracked inbound at 210° azimuth heading N at 45 miles range for about 1 min, first F-94 at 30,000 ft was vectored on 180° heading to attempt intercept at 20 miles projected range of target to radar site, but target reversed course over an 8-mile radius of turn (roughly 5 gs) and headed outbound at 1,500+ mph heading S and away from radar site and F-94. Pilot Lt. C. E. G. and radar observer Capt. V. D. R. on first F-94 tracked two targets, one strong one faint on. F-94 circled for an hour before getting another target at 12 o'clock low, dropped to 25,000 ft with 100-knot closure rate, no visual contact, had to pull up at 200 yards distance to avoid collision, F-94 released to return to base at 2:13 a.m. Pilot Capt. R. time also obtained radar lock on to a target at 12 o'clock high at 17,000 yards range for 2-3 mins. (BB Status Rpt 7; McDonald files; Jan Aldrich; FUFOR Index; cf. Ruppelt)

Jan. 22 [21?], 1952; SE of Mitchell AFB, New York (BBU)
9:50 am. (EST). USN TBM­3W bomber chased a a white circular domed-disc which shot away and climbed out of sight. (GRUDGE Rpt; Project 1947)

Brig. Gen. William M. Garland, Assistant for (Intelligence) Production, and his staff at the Directorate of Intelligence, HQ USAF, were briefed on the status of the Project Grudge UFO Study. At this meeting Gen. Garland introduced a revolutionary new intelligence policy and methodology which emphasized the use of instrumentation for intelligence collection, including to detect and track UFO's (which would eventually be the basis for terminating Project BLUE BOOK as an intelligence function, converting it to a PR psych war propaganda function beginning in July 1952 over a 6-month transition period). As an interim last-chance measure to prove whether anecdotal sightings had any value, Gen. Garland approves of  Ruppelt's publicity plan to draw in UFO reports from the public so that triangulations might be obtained, and this leads to Garland secretly backing the LIFE magazine article (plan backfires and is blamed for July 1952 flap). 

On the same date, Jan. 29, Gen. Garland gave the welcoming address to the SECRET compartmented MIT Project BEACON HILL in Cambridge, Mass., where he gave the marching orders to the assembled scientists to study ways AF intelligence methodology can be revolutionized through use of technology. (Later Gen. Garland sent Ruppelt and Col. Sanford H. Kirkland of ATIC, and Lt. Col. William A. Adams of AFOIN, to brief BEACON HILL on UFO's on March 26 and in April 1952, respectively).  (Credit Joel Carpenter for BEACON HILL.) (Brad Sparks)

Ruppelt Discovers AF Intelligence Has More UFO files
On this trip to the Pentagon to brief Gen. Garland, Ruppelt visits the offices of AF Intelligence (AFOIN) having collections of UFO files and discovers they have more complete files than does ATIC in Dayton, and he arranges to have copies made of the various missing files made for him at Project Grudge at ATIC (though multiple visits were required to obtain the copies and Ruppelt probably did not succeed in getting everything). These AFOIN offices with UFO files include the Technical Capabilities Branch (TCB) of the Evaluation Division (AFOIN-TCB or AFOIV-TC) and the Collection Control Branch of the Collection Division (AFOIN-CC or AFOIC-CC).  (Brad Sparks)


Jan. 29, 1952; Wonsan, Korea (BBU)
11:00 pm.  30 miles SW of Wonsan, USAF crew of B-29 flying at above 20,000 ft and 148 knots (170 mph) ground speed saw an orange luminous rotating and pulsating 3 ft sphere [or disc?], with blue flame halo, follow the B­29 at a distance of about 600 ft at the 8 o'clock position advancing forward to 9 o'clock then falling back to 8 o'clock [at one point almost withdrawing from view then returning?]. (LIFE Incident 9; Project 1947; Loren Gross)

Jan. 29-30, 1952; Sunchon, South Korea (BBU)
11:24 p.m. USAF crew of B-29 at 20,000 ft and 125 knots (144 mph) ground speed saw an orange sphere follow the B-29 at their level or slightly below [sun­like in brightness and 600 ft away?]. (LIFE Incident 9; Project 1947; Loren Gross)

The 1951 directive, "Reporting Information on Unidentified Flying Objects", which outlined reporting procedures for Project Grudge, was inadequate and was to be revised for Project Blue Book  (Pg. 59 of Project Grudge Report No. 3, 31 Jan 1952). The new one requested that all reports be made by wire to ATIC, ADC, and V/TC, and that this wire report be followed up by an AF Form 112 direct to ATIC and V/TC. (V/TC = AFOIN or AF Intelligence, Evaluation Division, Technical Capabilities Branch, which had been tasked by Gen. Cabell in 1950 to conduct field investigations of UFO cases independent of AMC/ATIC Project GRUDGE, and which TC Branch now had Capt. Dewey Fournet assigned) (Francis Ridge)

10:30 p.m. The 3903rd Radar Bomb Scoring Group observed an unusual radar return while attempting to score a bomb run. It was assumed at the time that the "target" was an aircraft pacing the bomber on its attack run, but the unusual target reached a speed of 1090 MPH. (McDonald list; BB Rpt 6) adar. (McDonald list; BB Rpt 6)

February 1952, Fournet Becomes AF Intelligence "Project Monitor"
Maj. Dewey J. J. Fournet in the AF Intelligence (AFOIN) Evaluation Division's Technical Capabilities Branch (TCB) replaces Lt Col Milton D. Willis as UFO investigation officer for AFOIN (in the June 1952 reorganization many assets in the Evaluation Division are transferred to the new Topical Intelligence Division, headed by Col. William A. Adams, including Fournet who is assigned to the Division's Current Intelligence Branch, headed by Col. Weldon H. Smith).  Fournet also assigned as "Project Monitor" for ATIC Project Grudge in the wake of widespread publicity on the Korean UFO sightings. (Brad Sparks)

Feb. 16, 1952; About 60 miles E. of Pusan, Korea (BBU)

Dendy, of a USAF C-54 aircraft, 53rd Troop Carrier Squadron, observed a bright orange oval-shaped object. The object, approximately 50 to 100 feet in length and 50 foot thick, was flying at a terrific speed at an estimated altitude of 10,000 feet and was observed for 1 1/2 to 2 minutes. Lt. Weed further stated that the object was definitely not a jet aircraft. (Project 1947; FUFOR Index)

March 13, 1952; Keflavik, Iceland
7:12 a.m. Eight separate unidentified radar sightings were made by a GCA team while working a C-47 aircraft on practice runs at Keflavik, Iceland. The first of the eight objects appeared at 0712Z (7:12 a.m. local time). The last object was observed at 8:09 a.m. The estimated airspeed of the objects was 250 knots and at estimated altitude of above 8000 feet. One report stated that one object crossed the scope at a speed much faster than an F-86. (Dan Wilson)

March 14, 1952; near Hawaii
Evening. Navy Secretary Dan Kimball was flying to Hawaii when two disc-shaped craft streaked in toward his Navy executive plane. "Their speed was amazing," he told Keyhoe later, in Washington. "My pilots estimated it between fifteen hundred and two thousand miles an hour. The objects circled us twice and then took off, heading east." Note that Adm Arthur Radford was a witness in a second plane.

Mid-March 1952, AF Initiates TOP SECRET UFO Project
AF Intelligence (AFOIN) Assistant for (Intelligence) Production Brig. Gen. William M. Garland initiates a TOP SECRET compartmented project (to be designed and built by AF R&D) to establish a global instrumented UFO detection and tracking system that would obviate the need for non-technical anecdotal UFO sighting reports, eventually resulting in approval of an official AF policy to deemphasize or reject anecdotal UFO reports (July 28, 1952).  (Brad Sparks)

Ruppelt: "I briefed General Benjamin W. Chidlaw, then the Commanding General of the Air Defense Command, and his staff, telling them about our plan. They agreed with it in principle and suggested that I work out the details with the Director of Intelligence for the ADC, Brigadier W. M. Burgess. General Burgess designated Major Verne Sadowski of his staff to be the ADC liaison officer with New Grudge."

March 25, 1952. Project BLUE BOOK Named
Grudge was upgraded to a separate organization, the Aerial Phenomena Group, and the name was changed to Project Blue Book. According to Ruppelt this change was made because of the steadily increasing number of reports we [the Air Force] were receiving. (Ruppelt, p. 131.)

March 26 [?], 1952; Ft. Stockton, Texas (BBU 1079)
2:10 am.

Stewart [Steward?] and George Tyler III saw 50 ft flat silver disc with cupola/dome to one side, a porthole and hatch on the dome, neon-like lighting around the edges [strangely pulsating?], approaching car from ahead to the NE about 60° elevation, then hovered and "wavered slightly" for 3 [2?] mins several hundred feet off the ground, whirring sound like a vacuum cleaner, car engine died while object hovered. Witness got out of car with Thompson submachine gun considering whether to shoot the disc, companion urged him not to. Object suddenly turned up on edge seeming to "roll across the sky" faster than a jet to the SW disappearing about 3-1/2 miles away. Witness claimed car wires "magnetized" and paint cracked. Secy. AF Finletter interest, AFOSI investigation. Hoax? (Hynek UFO Rpt pp. 196-8; Jan Aldrich; FUFOR Index; Loren Gross Jan-May 52 pg. 25)


"Have You Heard", by Bill Schofield. This was a bargain day in the flying saucer department, and you get two stories for the price of one -- the first from a resident of western Massachusetts and the second from Navy Sec. Dan Kimball.



ADC in near frenzied state
By the spring of 1952, Air Defense Command was in a near-frenzied state over the potential of a Soviet sneak attack. Its eyes and ears, the Lashup radar network and the GOC, had proven discouragingly unreliable, and, lacking credible intelligence on Soviet capabilities and intentions, it had no real basis for assessing the nature of the threat. (see report linked above). Little more than two weeks later, the worst possibility seemed to have come true. (See April 17)

April 2, 1952; Lake Meade, Nevada
9:00 am. While on a fishing trip to Lake Meade with his wife and a friend, a man observed a UFO. It was silver in color, very large and at a tremendous altitude. It was described as a B-36 without wings. Not a BB unknown.

April 4, 1952, Ruppelt Briefs Rand Corp. Satellite Project
Gen. Garland arranges for the AF-Rand Corp. Satellite Project to receive a UFO briefing from Ruppelt on a visit to ATIC.  Ruppelt meets and befriends Rand satellite engineer Jim Thompson. (Brad Sparks)

April 4, 1952; Duncanville, Texas (BBU 1095)
8:30 p.m. (CST)  USAF Cpl. Billy D. Greer and PFC John W. Harrington of the Radar Maintenance Section, 147th AC&W Squadron, tracked unidentified target by FPS-10 radar first to the NW at 310°-315° azimuth at about 70 nautical miles (80 miles) moving at high speed of about 2,160 knots (2,500 mph) until it disappeared off the scope at maximum range of 260 n.mi. (300 miles).  Height-finder reading not taken, estimated at 42,000+ ft due to radar beam coverage at max range.  (Jan Aldrich;  FUFOR Index)

9:15 p.m. L. E. VanDercar and 9 year old son saw 4  dark circular objects with mostly fuzzy edges, cross the face of the Moon [in the S at 175° azimuth 77° elevation, 83% illuminated or almost full], each 1/2 the angular size of Moon. (Berliner)

April 6, 1952; Temple, Texas [Miller-Graughan AFB?]. (BBU 1099)
2:59 p.m. H. L. Russell saw 50-75 grey­white discs change position within formation continually, tilting in unison every 12-15 secs. (Berliner)

When newsmen began asking him whether the article was Air Force inspired, Ruppelt replied that they had furnished Life with some raw data. My answer was purposely weasel worded, he said, because I knew that the Air Force had unofficially inspired the Life article... [and also knew that the strongly implied answer that UFOs were interplanetary] was the personal opinion of several very high-ranking officers in the Pentagon - so high that their personal opinion was almost policy. (Ruppelt, p. 132.)

Ruppelt:
The number of reports did take a sharp rise a few days later, however. The cause was the distribution of an order that completed the transformation of the UFO from a bastard son to the family heir. The piece of paper that made Project Blue Book legitimate was Air Force Letter 200-5, Subject: Unidentified Flying Objects. The letter, which was duly signed and sealed by the Secretary of the Air Force, in essence stated that UFO's were not a joke, that the Air Force was making a serious study of the problem, and that Project Blue Book was responsible for the study. The letter stated that the commander of every Air Force installation was responsible for forwarding all UFO reports to ATIC by wire, with a copy to the Pentagon. Then a more detailed report would be sent by airmail. Most important of all, it gave Project Blue Book the authority to directly contact any Air Force unit in the United States without going through any chain of command. This was almost unheard of in the Air Force and gave our project a lot of prestige.

Ruppelt:
In May 1952, Project Blue Book received 79 UFO reports compared to 99 in April. It looked as if we'd passed the peak and were now on the downhill side. The 178 reports of the past two months...had piled up a sizable backlog....During June we planned to clear out the backlog, and then we could relax. But never underestimate the power of a UFO. In June the big flap hit....- Capt. Edward J. Ruppelt, (Ruppelt, pp. 138-39.)

Early May, 1952; Willow Grove, PA
Time not given. The Naval Air Station Ground Control Approach radar picked up a target in bad weather conditions near the center of the scope. By the next sweep (32 rpm) the target had moved almost five miles, indicating the object was moving approximately 3,600 mph. It was seen to move as the trace swept past it. (A similar evnt occurred at Washington National in July where the target "blossomed" on the scope.) By the fourth sweep the target had moved off to the ten mile limit of the GCA scope. Target was visible on two radar scopes, operating on two different fequencies, so this was no malfunction. Object was tracked the next day under similar weather conditions. (Project Interloper, Jan Aldrich)

(Hynek UFO Report)

Richard Hall:
Through the first 5 months of 1952, the Air Force Project Blue Book investigators had noticed a build-up of UFO sightings. Then, according to project chief Capt. Edward  J. Ruppelt, In June the big flap hit....The objects displayed intelligent control by circling, maneuvering, reacting to pursuit, and otherwise demonstrating extraordinary capabilities unlike any known technology or natural phenomenon, such as sharp turns, rapid vertical motions,  and sudden reversals of direction. Radar repeatedly confirmed the presence of unidentified solid objects.

Ruppelt:
......the Air Force was taking UFOs seriously because a lot of good reports were coming in from Korea. Pilots were seeing silvery discs and spheres, and radar in Japan, Korea, and Okinawa all had tracked unidentified targets. (Ruppelt, p. 192.)

June 1952  CIA Prepares Secret UFO Report
In the wake of mass public and governmental interest in UFO's kindled by the provocative LIFE magazine article, CIA intelligence experts Sidney N. Graybeal (Chief, Guided Missiles Branch, Weapons & Equipment Division, Office of Scientific Intelligence OSI) and Irl D'Arcy Brent (Chief, Ground Branch, W&E Division, OSI) prepare a summary of the UFO subject for the CIA/OSI hierarchy based on the past several years of OSI intelligence (and OSI predecessor documents going back to ghost rockets of 1946) and mentioning sightings go back to the Bible.  Possibility of swamp gas in Michigan as an explanation for UFO's is suggested by Brent (foreshadowing the Hynek swamp-gas fiasco in Michigan in 1966).  (Report has never been acknowledged or released by the CIA despite FOIA litigation.  Report's existence and contents was revealed in Sparks interviews with Brent and Graybeal and other OSI officials in 1975-6.)  (Brad Sparks)

June 3, 1952; Chicago, Illinois (BB)
9:27 a.m. CST. Six to 10 targets were detected on AN/CPS 6B radar of the 755th AC&W Squadron.  These targets were at the GEO. REF. position of DM 3012, on a heading of 310 degrees at an altitude of 25,000 feet at an estimated speed of 450 mph. The controller on duty checked with C.A.A. and M.F.S. for flight plans, but they had no flight plans. These radar targets were then declared unknowns, and an F-86 aircraft was scrambled out of O'Hare Field. The F-86 flying at 29,000 feet was radar directed toward the unknowns and merged with the unknown track. The F-86 was unable to sight any aircraft at the position occupied by the unknown track. At 9: 46 a.m., the unknown track turned to a heading of 140 degrees and  followed the lake shore to position CM 5542. The unknowns then turned to a heading of 90 degrees and maintained this until position DM 3545. Now the unknown turned to a heading of 120 degrees and faded out at 10:16 p.m. The target indication was very strong on the PPI scope. During this incident a total of eight (8) aircraft were scrambled from three (3) different bases but no interception was accomplished. (Dan Wilson)

Dan Wilson:
On March 2, 1950, a Joint Chiefs of Staff; (JCS) meeting focused on establishing goals for a minimum air defense by 1952. The following month at a USAF Commanders Conference at Ramey AFB, Puerto Rico, planners familiarized commanders with the thinking behind the plan of minimum defense as well as with its contents. Referred to as the Blue Book Plan, it stipulated that a minimum air defense could be in place by mid-1952. It was estimated that July 1, 1952, as the critical date when the Soviets would pose a dangerous threat. General Charles Cabell expected the Soviets to have between 45 and 90 atom bombs and 70 to 135 Tu-4 bombers (copied B-29s) by that time.

Joel Carpenter:
On 1 July, nine wing B-36s (5-H and 4-F) departed Carswell to take part in a high altitude formation radar camera attack on New York City. Three aircraft were from the 9th, three from the 436th, and three from the 492nd Bomb Squadron. The nine B-36s flew to the orbit area at Cape St. Francis, Newfoundland, Canada, then flew the scheduled attack on New York City. From there the bombers flew to Montgomery, Alabama, and recovered at Carswell on 2 July. Following this, the wing presented the Meritorious Achievement Award Plaque to the Outstanding Tactical and Support Units in the wing. The 9th Bomb Squadron and 7th Maintenance and Supply Group received the awards on 5 July 1952.

Metcalf observed a milky white object shpaed like an "elongated oval" but "fatter than a cigar", about 100 feet in length or slightly larger than a four-engine airliner, having indistinct outlines at the rear resembling either a very short exhaust or a blurred tail section, with a narrow ridge along the top side, but without wings or any other aerodynamic features. (BB Files)

July 1, 1952; Fort Monmouth, New Jersey (BBU)
9:30 am. The objects moved south along the East coast and hovered near Fort Monmouth, N.J., for about 5 minutes at 50,000 feet. As radar at Fort Monmouth detected the objects, they put on a burst of speed and headed southwest toward Washington, D.C., confirmed visually. At about noon, a physics professor in Washington  reported seeing a grayish UFO hovering and arcing back and forth across the sky. (Ruppelt, pp. 200-202, Dan Wilson)

Ruppelt:
Without injecting any imagination or wild assumptions, it looked as if two "somethings" had come down across Boston on a southwesterly heading, crossed Long Island, hovered for a few  minutes over the Army's secret laboratories at Fort Monmouth, then proceeded toward Washington.

Richard Hall continues:
While driving through Utah in July, a Navy chief (later warrant officer) saw a formation of unidentified flat circular objects maneuvering in the sky, stopped and took color motion picture film of them. The objects defied conventional explanation when analyzed by the top Air Force and Navy photogrammetric laboratories.

July 2, 1952; Tremonton, Utah
Navy photographer Delbert C. Newhouse and his wife, while driving across the state, saw a group of 12-14 shiny silver objects milling around in the sky.

3:35 p.m. MST. A sergeant and three airmen of the 717 Strategic Reconnaissance Squadron, 28th Strategic Reconnaissance Wing reported that three milky white discs were between 30,000 and 40,000 feet. The airmen were lying on there backs off the edge of the East-West runway when they observed the objects which appeared between 3 and 4 inches in diameter (at arm's length), moving faster than any jet aircraft they have seen. Direction of travel: Northerly. The objects were seen one at a time with approximately one minute between sightings. Each object was observed for approximately 5 seconds. The significance of this report is just prior to the sighting a similar object was observed by other airmen at this station. (FUFOR Index)  3:30 p.m. Two more airmen at the east end of the East-West runway reported that an objects was observed at 20,000 feet or above. It was shaped like a disc and was grayish white and approximately 3 to 4 inches in diameter at arm's length, traveling faster than any jet they have ever seen moving to the north. The object came from a southwesterly direction and crossed over the northwest corner of the airfield. The object seemed to stop and hover over an area north of the East-West runway. It would lose some altitude and then reportedly gain it right back. (FUFOR Index)

8:18 p.m. Pilot of National Airlines Flight 42, a C-60 aircraft, saw a very bright amber glow, stationary then climbing slowly till disappearance. (Project 1947)

The crew of the Canadian destroyer Crusader saw two shiny discs and tracked them on radar.

July 10-17, 1952  Dr. Kaplan Visits ATIC Project Blue Book
UCLA Geophysics Prof. Joseph Kaplan, a member of the AF Scientific Advisory Board previously involved with a highly secret compartmented UFO tracking project in 1949 leading to Project TWINKLE, visits ATIC and Project BLUE BOOK, advising on plans for a top scientific panel to establish the importance and credibility of the UFO problem within the scientific community (a later distorted version of the plan is forced on the CIA by the AF as the Robertson Panel and intentionally designed by the AF to fail spectacularly). The Battelle Memorial Institute scientists are deemed not prominent enough to secure support within the scientific community, but will continue with statistical studies of BLUE BOOK's case files (ordered by Gen. Samford in Dec 1951 to specifically verify Ruppelt's sighting pattern analysis, showing UFO concentrations around atomic weapons bases, after his briefing disturbed Samford).  Battelle also continues special lab analyses of alleged UFO physical evidence from time to time.  (Brad Sparks)

July 12, 1952; Annapolis, Maryland (BBU 1431)
3:30 p.m. Insurance company president William Washburn saw 4 large, elliptical-shaped objects fly very fast, stop, turn 90° and fly away. 7-8 secs. (Berliner)

July 12, 1952; Northern Illinois
8:05 p.m. Report of unusual flying objects (Reference to July 12, 1952, Arlington, Illinois [BBU]) Air Intelligence Information Report from 755th AC&W Squadron, Williams Bay, Wisconsin. Mr. J. M. Stark, Chicago, reported that at 2005 CST he saw a greenish object traveling in horizontal flight. Object came to stand-still, then moved away at a very high rate of speed. Mr. L Matheis, Chicago, sighted object going east then turned westward, yellowish in color. Mr. L. Schrenk, Chicago, sighted object going north, weaving at low altitude, reddish in color. Mr. A. Cressy, Chicago, saw an object going north, turned west, not a jet type aircraft. Received call from 31st Division through ADCC, radars picked up strange objects heading west and north at 3000 mph and above.

July 12, 1952;  Williams Bay, Wisconsin
8:30 p.m. Air Intelligence Information Report describes radar tracks by three different radars. 31st Division through ADCC reported that Mastiff (AN/FPS-3), Orgin (FPS-10), and Cousin (AN/6PS-6B) radars had picked up strange objects in several areas heading west and north at different altitudes, 3000 mph and above.  (Dan Wilson)

July 12, 1952; Belleville, Illinois (BB)
8:30 p.m. Five radar observations of unidentified objects were made at the 798th AC&W Squadron beginning at 8:30 p.m CST. Object one: 8:30 p.m., 355 degrees at 200 NM, speed 1600 knots. Object two: 8:35 p.m., 30 degrees at 20 NM, speed 1700 knots. Object three: 8:47 p.m., 6 degrees at 190 NM. Object four: 8:49 p.m., 330 degrees at 180 NM. Object five: 9:20 p.m., 280 degrees at 175 NM. Visual Sighting at 2110Z  At 2110Z three airmen of the 798th AC&W Squadron, Belleville, Illinois, observed one very large round object of intense reddish orange color flying a straight course horizontal to the earth surface. The speed of the object was faster than any known aircraft. The object was observed for 20 seconds. One aircraft scrambled for observation purpose. The time given in the teletype (2110Z) may be incorrect. At around 2100 hours CST (9:00 p.m.), a large fireball-type object was seen by many witnesses in the Belleville/ St. Louis area. The object traveled in a straight line parallel to the ground from SE to the NW.  (Reference: Edwardsville Intelligencer, Illinois, July 14, 1952, page 1) (Dan Wilson)
