Fran Ridge:
This is a very comprehensive and qualitative effort. Without the help of Rebecca Wise (Project Blue Book Archive), Dan Wilson, Brad Sparks, Jean Waskiewicz, Bill Schroeder and others, this could not have been done. (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 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. 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.


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

Early 1952; Goose Bay, Labrador
10:42 pm. A fiery, spherical object made a right-angle turn during an observation by a C-54 crew flying from Westover to Goose Bay. It was also seen from the ground by the control tower and by two men who plunged to the earth when the object made a low pass at them. It went away at 10:47 pm.   (Quincy)

1952, Date unknown; Washington, DC  area 
Night. LCDR E. E. Kligington, John Ford, Michael Krause, pilots at Naval proving Ground Dahlgren, VA, flying F4U5 and F7F. Flying fighter aircraft, one at NPG one over Washington area and one over Fredericksburg at about 10-15,000 feet. When Krause saw a light close in front of him, he dived to avoid it, and made a sweeping climb to inspect it. Realized it was a large object between Frederickburg and Quantico. Krause also saw the object and headed for it and finally the other pilot did also.  They were approaching from N, S and about 5 miles it put on burst of speed and disappearing to the W.  Radar at Washington National and  MCAS Quantico supposedly watched the action. (George Fawcett's UFO report form filled out by E. E. Kligington).

1952, Date Unknown; Jacksonville NAS, Florida
11:00 p.m. Four sailors standing watch observed a black spearhead shaped object suddenly appear approaching from Jacksonville traveling N to S. The reporting witness was the first to see it, then the other three.  It stopped over NAS, with no slowing down, and then hovered for 15 seconds. While it hovered it looked like a dark spearhead in front of a dim yellow light.  Two aircraft took off at the same time, however, the witness did not know if it was related to the object. Suddenly the object left at a high rate of speed to the S.  Sighting was reported to the control tower that replied it was probably a weather balloon. (Reported in 2003)

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)
This case was incorrectly dated for years. A motionless dull-white, round object 5/3 larger than balloon. This incident occurred in 1951, not 1952. (See 1952 UFO Chronology for the reports and other details).

Jan. 20, 1952; Fairchild AFB, Wash. (BBU)
7:20 p.m. Three Air Force personnel, M/Sgt. Aluridus C. Holm, S/Sgt Robert T. Barnes, and T/Sgt Harry A. Gavagnaro (two of which were in Wing Intelligence) saw a large bluish-white spherical object with a long blue tail in the E about 2 miles away traveling N through the sky much faster than a jet aircraft. The object was.on a horizontal path estimated at 500 feet, was below and seen against solid overcast cloud cover at 4,700 ft, speed later estimated at 1,400 mph, no sound, disappearing in the W. (Sparks; Wilson, Ruppelt pp. 12-3; Saunders/FUFOR Index)  15 secs

Jan. 21, 1952; Mitchel AFB, N.Y. (BBU)
9:50 a.m. (EST). USN pilot Lt. James R. Zeitvogel, USN Special Devices Center, Long Island, flew USN TBM-3W bomber heading 45° (NE) at 160 knots (200 mph) at 6,000 ft shortly after takeoff from Mitchel AFB, sighted a 20-30 ft white circular domed or parachute-shaped, with parachute-like segmentation and dark underside, about 1/3 ratio thickness to diameter, which appeared to be about 1-1/2 miles to the WNW or half way between TBM and end of runway 30 at Mitchel AFB, silhouetted against the ground at a depression angle of about 45° at a very low altitude of 200-300 ft (consistent with ground range of 1-1/2 miles from TBM at 6,000 ft height). Pilot then chased object which was at first traveling about 300 knots (350 mph), by turning left in the TBM in a sharp 2-3 g turn, having to bank at almost 90° to see the low altitude object about 1- 1/2 mins into sighting when TBM about completed 360° turn, object cutting on inside of TBM’s turn apparently accelerating. Object at about 2 mins into sighting started climbing in altitude while still accelerating, disappearing suddenly not due to distance about 7 miles to the SW at 500+ knots (600+ mph) and about 10° above TBM’s horizontal level. (Sparks; GRUDGE Rpts. No. 3, p. 8, No. 4, pp. 9-11ff.; Project 1947; NICAP)

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)

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)

Jan 31, 1952; "AFOIN-C/CC-2 To Be Revised"
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)


Ruppelt Briefs ADC
In early February Capt. Edward Ruppelt 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."

(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)

Col. Ericksen, , Chief of the Technical Capabilities Branch, received this letter from: Albert E. Lombard, Jr. Chief, Research Division, Directorate of Research and Development. Re: Declassification of Project TWINKLE denied because Green Fireballs considered man-made.
Feb. 20, 1952; Greenfield, Mass.
A pastor of a German Congregational church boarded a trainand took a seat near a window. Like most travelers he gazed at the scenery to alleviate the boredom of the trip. Flashes in the cobalt blue excited his eyes as a brilliantly reflective trio of saucer-shapes approached in V-format ion. The formation quickly slowed, the object in the lead braking faster than its companions so to form a line of three abreast when all of the objects finally came to a complete stop. After a ten second wait, the objects shot off to one side so fast they were out of sight in about six seconds. It was an astonishing performance.(NICAP UFO Evidence, VII)

Feb. 20, 1952; Mt. Diablo, Calif. (BBU)
11:30 p.m. USAF pilot Montgomery and copilot of B-25 bomber saw bright yellow light on collision course climb and accelerate. (Project 1947; FUFOR Index)

Feb. 26, 1952; New Albany, New York (BB)
11:10 local. CIRVIS report says that in the vicinity NNW of Albany, New York, at an altitude estimated at over 50,000 feet, an unidentified object of unknown size and shape was apparently observing the reporting Air Force aircraft at 20,000 feet on a 90 degree intersecting course for approximately 20 minutes. Two jets pilots (Barnes [Sylvia 51] & Olshefski [Sylvia 41]) verified visibility, good sky clear, 80 knot wind at 230 degrees. Another CIRVIS report amplifying details describes the same object, sighted observing the aircraft (pilot Hensley) and traveling an estimated 1,000 mph and observed from distance of approximately 60 miles. Object of indiscernible color left pencil-thin whitish gray vapor trail approximately straight 10 miles long under non-concurrent observation for 3 to 5 minutes. Object was theorized to be a possible meteor!!!!

Feb. 27, 1952; Ft. Stockton, Texas (BBU)

March 4, 1952; 15 miles W of Ashiya AFB, Japan (BBU)
10:35 a.m. The pilot, 1st Lt. E.J. Weed, and crew, co-pilot 2nd Lt. T.G. Camidge and engineer S/Sgt. T. 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)

1 a.m. USAF copilot of C-54 transport saw a bright light pass from right to left, lose altitude and blink out 3 times. (Project 1947; FUFOR Index)

An engineering metals inspector watched two dark wing (or hemisphere) shaped objects pass overhead, swaying back and forth like a pendulum. (NICAP report.)

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. (See details at link).

March 15, 1952; Sandia Mtns. [Kirtland AFB?], New Mexico (BBU)

March 17, 1952; Ionia, Michigan
A wobbly, tipping object that resembled two saucers placed edge to edge, crossed the sky, flashing a silver light. (Gross, UFOs A History 1952, 99,. [Ionia, Michigan] Ionia Daily Sentinel Standard, 18 March 52.Vitello)

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."

8:45 a.m. [p.m.?] B-29 navigator and radar operator tracked unidentified target on airborne radar at about 3,000 mph. (Berliner; Shough)

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. SW of Pecos, NW of Stockton, Texas and Arizona  [8:30 and 10:13 p.m. ?] USAF pilots of 4 B-50D's [McClelland and 3 others] saw red and green running lights moving at high speed. 2nd sighting over Arizona at 10:13?

March 29, 1952; Butler, Missouri
Chairman of Industrial Commission of Missouri saw cylinder-shaped, silver UFO, [UFOE, VII]

March 29, 1952; Elizabethville, Belgian Congo. (BBU)
Two fiery discs were seen over uranium mines gliding in curves, changing orientation many times thus appearing as plates, ovals and lines. Discs suddenly hovered then took off in a zigzag to the NE. Commander Pierre of Elizabethville airfield took off in a fighter aircraft in pursuit and came within 120 meters (400 ft) of one disc. (McDonald files; Jan Aldrich)

March 29 [April 24?], 1952; Glen Burnie, Maryland. (BBU)
10:45 p.m. Donald F. 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.

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 Mead, Nevada (BB)
9:00 am MST. While on a fishing trip to Lake Meade with his wife and a friend, Master Sergeant Sheldon Smith observed a UFO. It was silver in color, very large and at a tremendous altitude. It was described as a B-36 without wings. Observed right after a flight of F-86's overflew the area at about 15,000'. His friend was also a M/Sgt Lester Gossett. After watching the hovering object for about an hour, which was much higher than the vapor trails from the F-86's, it suddenly disappeared. Smith filed his report with an intelligence officer in accordance with AF requests to report such observations. (Fran Ridge, AIR, BB files).

On the eve of the release of the bombshell LIFE magazine article, Ruppelt and his boss, ATIC Technical Analysis Division Chief Col. Sanford H. Kirkland, give an extraordinary briefing, technically unclassified but in fact quasi-classified, to a group of aerospace engineers organized as Civilian Saucer Investigations, in Los Angeles, along with LIFE magazine reporters who give them advance copies of the article in exchange. (See extremely rare and revealing Transcript obtained by Project 1947.)  (Brad Sparks)

April 3, 1952; Marana, Arizona. (BBU)
8:23 a.m. MST  Pilot of a T-6 aircraft and six other pilots on the ground, saw a bright silver circular object 5 or 6 times the size of a B-29 at an estimated 55,000 ft.  C. M Jasper, Squadron Commander & Flight Instructor, Marana AFB, sitting in a landed T-6 aircraft at the Benson Airport, took a fix on the object in relation to the top of the canopy at 0823. Paul Wilkerson, Flight instructor, Chauncey (Chick) P. Logan, Flight Instructor, Marana AFB, Cadet Plucinsky, Chuck (Skeet) Taylor, Airport Manager were some of the other witnesses.  Jasper kept continous fixes on the object and it did not move the slightest fraction until 0914 when the object disappeared. Cadet Plucinsky flying above Benson airport, said when he spotted the object; "It looks like a flying saucer." Object hovered for over 51 minutes then suddenly disappeared.

2:59 p.m. Herman L. Russell saw 50-75 greyish-white metallic disc-like shapes to the NNW about 30° ­ 40° elevation in random arrangement within a circular formation covering area of only 1 Full Moon [hence each object probably <3 arcmins would have been too small to resolve disc-like details]. Objects would flash in unison every 12-15 secs for a period of 2 secs as if tilting on horizontal axis. After 2 mins cluster became less dense in the center and more dense at the outer rim. Formation estimated at distance of 15-25 miles [hence height about 50,000 ft] moved upwards in elevation by about 5° and laterally by 10° to 15° (direction not specified) until disappearing by fading into distance. [Possible shattered plastic fragments of Skyhook balloon fluttering in the sunlight.] (Sparks; BB Maxwell Microfilm Roll 9, pp. 1303-4; 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.

5:00 pm. Two civilian witnesses reported to the Air Force that an object in the SE that resembled a white parachute was apparently circling a large airplane for about three minutes. Not listed in BB unknowns or Sparks CCPBBU.
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.

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.)

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.

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.

......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)

The object/light crossed in front of the C-47 aircraft at about 7,000 feet, about 2,000 feet higher than the C-47. The object was on a heading of approximately 270 degrees at a speed as great or greater than a jet fighter at cruise. The object was estimated to be 1 to 2 miles west of the C-47 and at this time the object made a fairly tight turn of approximately 145 degrees. The pilot, Capt. Gerald M. Jones turned the aircraft to try and intercept the object. The object approached rapidly. At this time Capt. Jones was able to observer the silhouette of the object. It appeared to be circular with white lights on the leading edge. At this point the object made a sharp turn to the left on a heading of 270 degrees and disappeared under the nose of the aircraft. The estimated total time the object was observed was not more than 3 minutes. (Weinstein, BB files, Dan Wilson)

Early July 1952  Mysterious Dr. "X" Predicts UFO Flap
A mysterious government scientist visits Ruppelt at Project BLUE BOOK and predicts the UFO flap, as hitting New York City or Washington, D.C. I have identified this Dr. "X" as Dr. Stefan T. Possony, Acting Chief of the AFOIN Special Study Group and top scientific adviser to AFOIN Director Maj. Gen. John A. Samford, who was also a leading military strategist and psychological warfare expert. Possony evidently studied the plans for the continental joint SAC-ADC operation Exercise SIGN POST planned for late July and deduced that the planned simulated SAC "attack" on either NY or Washington to test ADC air defenses would trigger false UFO sightings (and in fact SAC did "attack" Washington, but the simulated air raid was on July 23 not on the July 19-20 or 26-27 dates of Washington National UFO incidents).

2:30 p.m. MST (2130hrs UTC). USAF pilot John Lane, who was in a swimming pool, sighted an object in the sky, using his naked eye. When he looked up, he saw one, white, round object [based on a comparison to the Moon – estimated angular size was 0.1 degree] travelling in a straight line from west to east. He estimated it was initially seen at 45-degree elevation; it then passed across the face of the Sun and was then visible on the other side, and lost to sight at an estimated 30-degree elevation. Total duration was 10 seconds. Sky was clear blue; with little or no wind. A telex says the object’s true heading was about 70 degrees. (Greenwood, Basterfield, Fold3; Sparks PBB unknowns; Berliner. ) [Note by Keith Basterfield. At UTC 1952-06-19 21:30 the Sun was at an elevation of 64 degrees, at azimuth 255 degrees.

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.

July 1, 1952; Lynn & Bedford, Massachussetts (BBU)
7:25/7:30 a.m. (EDT).  2 F-94's scrambled (at 7:25?) to intercept UFO that a GOC spotter saw heading SW over Boston, no radar contact and F-94's searched area found nothing.  Erwin W. Nelson and wife at Lynn (9 mi NE of Boston) at 7:31-7:34 noticed two vapor trails from the climbing jets, looked around, saw in the W a bright silver "cigar shaped object about six times as long as it was wide" heading SW over Boston at a very high altitude, speed a little faster than the two jets. An identical UFO was following the first some distance back.  No vapor trails.  Witnesses watched the F-94's search back and forth far below the UFO's. At 7:30 AF Capt. Robert E. Metcalf, Petroleum Officer, 6520th Supply Sq, 6520th Test Support Wing, and USAF air policemen MSgt James Stiner and MSgt Joseph R. Bosh, 6520th Air Police Sq., near Hangar B, Hanscom Field, Bedford, Mass. (15 mi NW of Boston, W of Lynn) saw the two jets, looked for what they were intercepting and saw to the E [?] a 100 ft long silvery ellipse “fatter than a cigar” traveling SW but did not spot the 2nd UFO. At two points object seemed to hover for a few secs, then continued at about 40,000 ft.  Object path intersected contrails of the two jets heading SE.  Metcalf lost sight of object on his way to the Tower after a few (2-3?) mins then caught sight again at about 7:40, noting it had increased distance “considerably,” but lost it at the Tower and unable to see it with unaided eye or 7x50mm binoculars.  (Sparks;  Maxwell BB Microfilm Roll 11, pp. 485ff.Ruppelt) 15+ mins 7+ witnesses

July 1, 1952; Lexington, Ma (BBU)
7:30 AM. Capt. Metcalf observed a milky white object shaped 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, Sparks)

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)

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 1, 1952. Washington, DC. (BBU)
George Washington Univ. Physics Professor saw “dull, gray, smoky colored” object in the NNW sky hovering motionless about 30°-40° above

Angular size ½ of a quarter (coin) at arm’s length [=1°]. He estimated at least 500 other witnesses in the streets, confirmed by brief newspaper reporting. (Sparks; Ruppelt)

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. Newhouse stopped and retrieved his 16 mm camera and filmed extensive footage of the objects.  He and his wife both reported seeing some of the objects relatively close-up and they were shaped like one plate inverted atop another. When the film was returned to Newhouse following Navy and Air Force analysis, the frames showing the discs close-up had been deleted.

Early July 1952  Mysterious Dr. "X" Predicts UFO Flap
A mysterious government scientist visits Ruppelt at Project BLUE BOOK and predicts the UFO flap, as hitting New York City or Washington, D.C. I have identified this Dr. "X" as Dr. Stefan T. Possony, Acting Chief of the AFOIN Special Studies Group and top scientific adviser to AFOIN Director Maj. Gen. John A. Samford, who was also a leading military strategist and psychological warfare expert. Possony evidently studied the plans for the continental joint SAC-ADC operation Exercise SIGN POST planned for late July and deduced that the planned simulated SAC "attack" on either NY or Washington to test ADC air defenses would trigger false UFO sightings (and in fact SAC did "attack" Washington, but the simulated air raid was on July 23 not on the July 19-20 or 26-27 dates of Washington National UFO incidents). (Brad Sparks)

Oscar Linke, former Wehrmacht major, and his daughter Gabrielle, 11, had to leave their motorcycle when they had a flat tire. Inside the woods the girl noticed two men in silvery suits examining the ground in a clearing near a pink disk-shaped object, 8 m in diameter, showing a double row of openings around the rim and a black turret on top. One of the men had a flashing box. Both men went inside, and the disk vibrated, rose along the turretlike cylinder, then spun faster and rose out of sight. (Guieu 52)

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)

Many FPS-10 radar controllers at 790th AC&W Sq tracked large radar blips at 1,500+ knots (>1,700 mph) to 4,800 knots (5,600 mph) [actual speeds about 5,000 to 6,000 mph in all 6 tracks] inbound and outbound on nearly identical straight-line azimuths in about the 124-293 mile range [suggestive of real objects below about 20,000 ft within the Vertical-Lower beam of FPS-10 but not caught within higher-aimed Vertical-Center or Vertical-Upper beams limited to >2° elevation angle]. 6 single targets each tracked at following azimuths (at times listed above) coming to/from 142°-134°, 001°-354°, 220°-202°, 321°-320°, 320°, and 004°, with none crossing to other side of scope, a classic interference pattern except none extended to center of scope or to outer edge but disappeared like a real object in and out of radar blind zones. Checks with regional radar stations found none with antennas "in opposition" (matching direction of
Kirksville radar antenna at the same moment). No visual sighting, or other confirmation of targets by other radars [apparently not even by the other component radars within the FPS-10 operating on different frequencies, such as the Slant-Lower beam which would have given height data,none reported, which suggests interference or selective radar emissions or ECM]. Radar targets registered only every other sweep (every 30 secs of the 4 RPM sweep rate) suggesting interference by a 2 or 6 RPM sweep rate radar. Possible IFO non-real radar interference.

9:12 p.m. (EDT). Pan American Airways FO William B. Nash, Second Officer William H. Fortenberry, in a DC-4 airliner at 8,000 ft heading 200° magnetic, sighted a total of 8 large, round, glowing red coin­shaped objects, 100 ft diameter 15 ft thick, maneuvering in two groups of 3 then joined slightly after by another 2. Objects approached head on at high speed estimated at about 12,000 [27,000] mph at about 2,000 ft altitude [about 2° depression angle] silhouetted against the ground, to a position almost directly below their airliner, in a stack formation then suddenly making a 150° hairpin turn like balls bouncing off a wall, joined by 2 more identical but much brighter red objects which came from behind on the right under the aircraft at about the same 2,000 ft altitude as the first 6 objects joining formation by falling in behind, all silhouetted against the black background of bay water, with one moment when all 8 objects blacked out then reappeared. At about 10 miles S of Newport News objects ascended as a group in fixed formation in an arc to the right towards Newport News to about 10,000 ft altitude [about 0.4° above level or about 2° above horizon line] out to disappearance by blinking out randomly, after covering a total distance of roughly 90 miles from start to finish (35 miles on approach, 55 miles to departure). Possibly 7 ground observers. (Sparks; McDonald; Tom Tulien; Joel Carpenter)

July 14, 1952; near Okinawa
10:10 p.m. local time, at Kadena Air Base, Okinawa, S/Sgt Eugene K. Chalmers and 2nd Lt. Phillip Galtieri, observed a spherical object to the north of the base. The object was moving straight down, but its course changed immediately as it moved to the northeast across the sky. When change of course occurred, the object appeared to slow down and almost stop in midair. The object then  picked up considerable speed and vanished.

July 14, 1952; Holloman AFB, New Mexico (BB)
10:20 MST. Unidentified objects were observed over the missile test range at Holloman AFB, during a Hughes Aircraft project mission. Two hundred feet of 35mm. film was taken of two maneuvering objects at a high elevation angle to the NNE. Two other witnesses that were watching the B-29 on the mission through 6 power binoculars saw an object cross in front of the B-29 with about the same size and apparent speed as the project F-86 would have, but the object was not the F-86 which overtook the B-29 shortly thereafter. Mr. H. R. Morris and Mr. Floyd Fannon, on X-Band radar for the project observed something on their  "A" scope which appeared like a jet going the opposite direction from the B-29.  A bright object was observed passing through the field of vision by an optical tracker using a 20 power monocular scope near the radar site. The object was observed above the B-29  and going the same general direction, but much faster. The "Pip" on the radar "A" scope on X-band modified SCR-584 was about the size and apparent speed as a jet fighter would give at 35,000 feet, and was observed for a few minutes. (Dan Wilson)

11:40 p.m.-6 a.m. (EDT). Numerous visual, radar and radar-visual sightings by ground observers and pilots in the air. 6 hours 20 min. (Sparks).

Richard Hall:
Shortly after midnight civilian radar operators at National Airport began tracking a group of 7-10 unidentified targets southwest of the  city, moving  about 100-130 m.p.h. An  individual  object  would  disappear from the scope at intervals, then another target would appear.  This continued for about 6 hours, while airline pilots in the area reported sighting unidentified lights in the positions where radar detected unexplained targets. They were not any known aircraft.

Senior air route traffic controller Harry G. Barnes:
"There is no other conclusion I can reach but that for six hours on the morning of the 20th of July there were at least 10 unidentifiable objects moving above Washington .... I can safely deduce that they performed gyrations which no known aircraft could perform. By this I mean that our scope showed that they could make right angle turns and complete reversals of flight."

July 20, 1952; Dai-el-Aouagri, Morocco
12:30 am. Approximate date.  Man named Petijean saw a luminous object, 20 m diameter, on the ground. It gave off bluish flashes as it took off, leaving a smell of burning sulphur. (Quincy)

July 20, 1952; Andrews AFB, Maryland (BB)
After midnight. At around midnight various people in the Andrews Tower were talking about flying saucers. At this time T/Sgt John P. Izzo went up to the tower and heard Washington Center call the tower on the intercom advising that they had 5 unidentified targets over the Andrews range. Nothing appeared on the Andrews radar. A/1C William B. Brady gave the statement that Airman Goodman called the tower at around 12:05 a.m. and advised for him to look to the south immediately. When Brady looked he saw an object like an orange ball of fire trailing a tail at about two miles south and one half of a mile east of the Andrews range. The object made a circular movement and then took off at an unbelievable speed. Seconds later Brady saw another such object that made an arc like pattern and then disappeared. Later, Capt. Harold C. Way reported that Washington Center called and ask if Andrews radar had a target 3 miles north of Riverdale. Way checked the radar and there was a motionless target at the place Washington Center had indicated. It remained for about 25 to 30 seconds and then disappeared completely. (Dan Wilson)

July 23, 1952; Culver City, Calif.
Several aircraft plant employees saw a bright silvery elliptical object that moved northwest, then stopped and hovered. Two small discs emerged and circled around the area before rejoining the mother ship. The object then climbed straight up out of sight at tremendous speed.

July 23, 1952. Near Boston, Mass (BBU)
1:15-1:18 a.m. (EST). Watch duty CG Seaman Henry Arnpriester, Nahant Coast Guard Station, sighted 2 bluish flat disc-shaped objects side-by-side estimated 5 ft in diameter (at 1,100 to 2,000 ft altitude?) in the SE at about 45° elevation descending and headed NW towards him until reaching distance of about 1-1/2 miles when suddenly reversed direction like “a ball bouncing off a wall” returning to SE and climbing without any change in apparent speed until gradually disappearing due to distance. [See July 22 sightings near Boston / Braintree, Mass.] (Sparks; AFOSI files; Saunders/FUFOR Index)

July 23, 1952; Nahant, MA
2:15-218 a.m. A Seaman on watch at Nahant Coast Guard Station observed two (2) bluish lights approximately 5 feet in diameter, appearing as flat, disc-shaped objects having no aerodynamic features and moving without sound or exhaust trail at a speed faster than a four-engine airliner at an altitude of 1,100 to 2,000 feet. When they were at a distance of approximately 1 1/2miles from the point of observation, they executed an extremely sharp turn, described by observer to be similar to the path of a ball bouncing off a wall. (BB files)

8:40 a.m. 2-man crews of 3 USAF F-94 jet interceptors saw a large silver object, shaped like a long pear with 2-3 squares beneath it, fly at 150-180 knots (170-210 mph), while a smaller object, delta-shaped or swept back, flew around it at 1,000-1,500 knots (1,150­1,700 mph (Berliner, Schroeder)

July 23, 1952; Alexandria, Virginia
9:00 p.m. A red object, size undetermined, was sighted southwest of Alexandria, Virginia. The object hovered for 10 minutes, then disappeared in a westerly direction at a high rate of speed. The witnesses were a County Policeman, two airmen and a civilian. (BB docs) (Note: The Alvin Moore "Fragment" was found at Vienna, Virginia, which is WNW of Alexandria. Alexandria is where the red object was seen on July 23, 1952. The object was last seen moving to the west).

July 23, 1952; Nr. Washington, DC
9:00 p.m. Air Force jet shoots at UFO. Wilbert Smith (Canadian Project Magnet) admitted that a number of fragments from UFOs had been recovered and analyzed by his research group, including one that had been shot (by AF jet) from a UFO near Washington (Alvin Moore fragment). Said Smith: "I was informed that the disk was glowing and was about two feet in diameter. A glowing chunk flew off and the pilot saw it glowing all the way to the ground. He radioed his report and a ground party hurried to the scene. The thing was still glowing when they found it an hour later...." (See Frank Edwards audiotape)

(Blue Book files/Dan Wilson)

July 23, 1952, near Springfield, Ohio
Bt. 8:05 and 10:15 p.m.  two lights, some described them as white globes, were seen high in the sky. Jet aircraft were seen near where the lights were seen and later it was learned that the 97th Fighter Squadron had scrambled some of its planes and they were investigating the incident. At 8:05 p.m. (2055), Major A. S. Griffin, Base Comptrollers Office, called in a report that while he was at the scout camp near Yellow Springs, Ohio, at almost dark, he had seen three lights high above the Springfield Municipal Airport. He watched the object through field glasses and he said there were two jets that appeared to be investigating.

July 23, 1952; Lockbourne AFB, OH
This case was investigated by OSI. Numerous witnesses observed four (4) objects hovering in the vicinity of the Lockbourne AFB, Columbus, Ohio. The objects were round and fluorescent white in color. Two F-84 jets were dispatched from Lockbourne AFB, but were unable to identify the objects. Approximately 90 per cent of the personnel at the base observed the objects. Later through means of triangulation the objects were determined to be at 75,000 feet in altitude.

July 24, 1952; Vico, Italy
A man who was fishing in the Serchio night River saw a disk hovering for 10 min. From it hung a hose that plunged into the water. The object was 20 m in diameter, with five propellers in the rear and a dome with something like blades on top. An orange glow could be seen through slits along the deck. A man wearing a diving helmet looked at the witness through a window, and he received a kind of electric shock as a "green ray" hit him. He looked up with difficulty, in time to see the object fly away toward the east. Six days later a stranger with a foreign accent contacted the witness and intimidated him. (FSR 69,1)

July 24, 1952. Carson Sink, Nevada. (BBU 1584)
3:40 p.m. (MST). USAF HQ Directorate of Operations Lt. Cols. John L. McGinn (Deputy of Ops, Fighter Br) and John R. Barton (AFOOP-OP-D) flying E in a B-25 bomber at 11,000 ft and 185 knots airspeed saw 3 silver white, delta-shaped or arrowhead-shaped objects at their 1 o'clock position slightly larger than the size of F-86's (40 ft), each with a ridge along the top, in V­formation, cross in front of and above the B-25 from right to left (S to N) at about 1,200 to 2,400 ft away at about 1,800+ mph.

10:45 p.m. USAF pilot and copilot of bomber with 364th Bomb Sq saw high speed object over MacDill AFB tracked by ground radar. (Project 1947; McDonald list)

July 24, 1952; Elmendorf AFB, Alaska
11:20 p.m. (0820Z July 25). 1st Lt. Jones, pilot, and 2nd Lt. Aubrey M. Brenner, radar observer, while flying in an F-94 SE of Talkeetha, Alaska, made radar contact which appeared larger than an F-94 at 14,000 yards. Lock-on was accomplished at this time with a target speed of 40 knots greater than of the aircraft. Aircraft speed was increased to 350 knots in a 4200 feet per minute climb. The target was still pulling away at over 100 knots. After a climb to 18,500 feet the target appeared to level off and increase speed. The chase was broken off at this time.

July 24, 1952; Clovis, New Mexico
2130 hours. 140th Fighter-Bomber Wing. First page of document states that unidentified flying objects similar to types reported seen over "Operation Desert Rock" (Oct. 30, 1951) were observed by an officer of this wing on July 24, 1952.

In late July the 1952 wave reached some kind of a peak, with fantastic sightings happening one after the other. All across the United States from July 25 through early August, Air Defense Command radar detected unknown objects flying through the skies, and jet interceptors scrambled to pursue them saw unidentified luminous objects exactly where both ground and airborne radar showed them to be. These sightings had profound implications for national defense, and accordingly were treated with great urgency. A lot of the details were kept secret from the public, but the cat was out of the bag on publicity because too many highly credible people were reporting sightings and the news media were looking for answers.

July 25, 1952; Manassas, Virginia (BB)
At around 12:00 a.m. EST, a bright light was observed in the sky east of Manassas by members of the 647th AC&W Squadron. The object was extremely bright. The object was in view for approximately 4 hours. Two F-94 pilots from the 148th Fighter Interceptor Squadron were scrambled to intercept an object. The two F-94 pilots sighted the object but estimated the altitude to be far beyond the capability of their aircraft. Number of observers: At least 2 from the air/ several (11) from the ground. (Dan Wilson)

July 25, 1952; Wilmington, Delaware (BBU)
Afternoon. VA employee saw 2 discs reflecting light in a climb.

July 25, 1952, Osceola, Wisconsin (BB)
Numerous unidentified objects were picked up on radar by the 674th AC&W Squadron in the morning. Speeds varied on the radar scope between 14,400 knots and 20,000 knots. There was correlation between these electronic sightings and visual sightings made by pilots of the 109th Fighter Squadron from Minneapolis, Minnesota.

Joel Carpenter:
JOINT SAC/ADC EXERCISE. The next flying exercise took place on 27 July, as the wing launched 21 B-36s (7-9th, 7-436th and 7-492nd Bomb Squadron) from Carswell, as part of a joint SAC/ADC attack on Detroit, Michigan. En route to Detroit, the bombers were intercepted by Air Defense Command North American F-86 and Lockheed F-94 fighters. The North American F-86 Sabre was the Air Forces first swept-wing fighter, entering operational service in February 1949. The Lockheed F-94 Starfire was the first jet-powered all-weather fighter to enter service with the Air Force and first to feature a speed-boosting afterburner. It became operational in May 1950 with the Continental Air Command. Fighter opposition was considered ineffective as all bombers attacked the target then returned to Carswell the same day.

July 27 [25?], 1952; Wilmington, Delaware (BBU 1664?)
At 2300Z Mr. James R. Thomas observed one cylindrical object with a domed top and bottom moving northwest to southeast. The object appeared to move in an upright position. The object disappeared suddenly. Sighting lasted for approximately 90 seconds.

Biologist reported "flotilla" of rocket-like UFOs. [UFOE, VI]

At 6:35 p.m., a group of eight witnesses including  pilots  and engineers  observed a large silvery object moving rapidly at high altitude, then making a turn. As they watched, the object separated into seven discs which then formed into groups, circled, and sped out of sight. It appeared as if a stack of coins had smoothly separated, the pilot told  investigators. (Air Force Intelligence  report.)

July 27, 1952; Belleville, Illinois (BB)
Bt. 7:20 p.m. and 8:30 p.m CST.  Four objects were observed on ground radar equipment (FPS-3) of the 798th AC&W Squadron. The objects were eliptical in shape and the target return was comparable with B-50 or B-36 echos. The speed of the objects was estimated at 2,800 to 3,200 knots and the direction of travel was from south to north and north to south. (Dan Wilson)

July 27, 1952; Washington, D.C.

July 28-29, 1952; 20 miles W of Port Huron, Mich (BBU) [CCL Item #17]
9:40-10 p.m. (EST). An Aircraft Control and Warning Station in Michigan, July 29, 1952, reported an extremely important case: Ground Control Intercept tracked UFO by radar, target speed 550 knots. Chased by F-94s; one got a radar lock-on; bright flashing light seen at the same time, same position. Although numerous incidents involve clearer, closer encounters, this was one that convinced a lot of people simply because of what the UFO apparently did. (See Digesting the Data below) This was item # 17 on the Chop clearance list. Surprisingly, the case is not listed among the Blue Book "unknowns", but there were no less than six "unknowns" on that very day. Two days prior to this was the Selfridge ADC attempted intercept mission.  Less than a week later, the Port Huron case was upgraded to SECRET.

July 29, 1952; Enid, Oklahoma
Sidney Eubank went to the Enid police station and told Sergeant Vern Bennell that an enormous disk had buzzed his car as he drove between Bison and Waukonis on Highway 81. The rush of air made the car leave the road while the object flew west very fast. (Anatomy 134)

July 29, 1952; Osceola, Wisc. (BBU 1731)

CAA radar in the early  morning tracked 8 to 12 UFOs at a time traveling  about 100-120 m.p.h. in a 10-mile arc around the Nations Capital. When an Eastern Airlines pilot tried to check on the radar targets at CAA request at 3:00 a.m., he saw nothing. The targets disappeared from CAA radar screens when the airliner approached, then came back in behind him after he passed through the area.

July 29, 1952; Walker AFB, Roswell, New Mexico (BBU)
4 weather observers including base weather officer sighted several high-speed discs through theodolite. (Hynek UFO Rpt. pp. 114-5)

July 29, 1952; Los Alamos, New Mexico (BBU) [CCL Item #18]
10 a.m. Several Los Alamos Scientific Lab and other witnesses saw white object moving E to W, about 1.8°/sec angular velocity, with gyrating or fluttering motion. 2 jet interceptors from Kirtland AFB arrived about 5 mins later chasing object W to E, all 3 leaving contrails. At 10:57 a.m. light-brown egg­shaped object with wings was sighted hovering then shot off to the NW disappearing in 3 secs. 30 secs. (Hynek UFO Rpt pp. 61-64)

July 29, 1952; Albuquerque, New Mexico [CCL Item # 19]
9:15 p.m. Witness saw a flight of luminous objects, at least 10, pass over Albuquerque. "Whatever they were, they made a  “flying saucers” believer out of me. They resembled nothing I has seen before. Their flight was soundless and graceful. At first they appeared overhead.They were clustered together in no apparent pattern, heading north.Then they shifted to a perfect V. the shift was done with precision. The formation resembled a flight of geese. Within a few seconds they formed a new pattern ­ two rows with the objects in front spaced at exact intervals. The “saucers” in the second row were spaced evenly between those in the first row." (Dan Wilson)

What was characterized as the largest Air Force press conference since the end of World War II was held, with Maj. Gen. John A. Samford, Director of Air Force Intelligence, presiding. He attributed the radar-visual UFO sightings to weather effects, temperature  inversions that caused radar mirages. 41-second sound byte (Courtesy, Wendy Connors and the Faded Disc Archive)

12:35 p.m. USAF shop employees Douglas and Hess at Municipal Airport saw a bright white circular object with a flat bottom fly very fast then hover 10-15 secs over the Cessna Aircraft Co. plant. 5 mins. (Berliner)

Bt. 2:00 p.m. & 3:00 p.m. MST. The sighting at Ennis, Montana was made by Ben Shaffer and about 11 other witnesses. At a time between 1400 and 1500 hours MST, Shaffer saw an object hovering over a mountain while driving his car. He stopped the car. The object then formed a cloud around itself. Shortly after three smaller disc like objects came bursting out of the cloud from different angles at an estimated 200 mph. The objects accelerated into an arc and disappeared. Shaffer had eight-power binoculars when he was watching this action. Shaffer stopped two other cars, one from Ohio had 50-power binoculars. Now there were about 12 observers watching with the naked eye and through binoculars. After the 3 disc like objects had left the cloud 5 objects appeared on the right side of the cloud in V formation traveling slowly and then each of these objects formed a small cloud around themselves. Then these objects one at a time entered the big cloud one behind the other. There were no other clouds visible in the sky within range of vision. During this time Shaffer took colored moving pictures with a Bell and Howell camera and still pictures with a Kodak Retina camera. Shaffer turned the undeveloped films over to Major McCarthy of the 29th Air Division at Great Falls AFB, Montana. After watching this phenomenon for about 30 minutes another cloud formed to the left of the highway and the same phenomenon occurred with objects leaving and returning.

July 29, 1952; Ennis, Montana (BBU 1747)
3:40 p.m. MST. USAF personnel, alerted that UFO's were coming from the direction of Seattle, saw 2-5 flat disc-shaped objects, one hovered 3-4 mins, while the others circled it. Sighting length of 30 mins not explained further. Sgt. Boden at Great Falls AFB, Mont., heard a transmission from McChord AFB, Seattle, Washington of  'flying saucers' hovering there and that the saucers were headed towards Great Falls AFB, Montana.

9:30 PM. Mayher movie  Ralph Mayher, using 16 mm film exposed at 24  frames per second, obtained good footage of a high speed UFO. Retaining a few frames for personal study, Mr. Mayher submitted the main portion of the film to the Air Force for analysis. The film was never returned and no analysis report was ever released. Enlargements of a few frames show a fiery looking roughly circular object, symmetrical, with two small peaks or projection on opposite sides of the disc.

10:00 a.m.  George and Everett Nye observed one round object giving off a  bright luminous color like a glittering diamond. The object hovered directly overhead at approximately 5,000 feet and upon approach of a C-97 aircraft it made a rapid ascent to approximately 10,000 feet. The object then moved off laterally at a tremendous rate of speed many times faster that conventional aircraft. The observers also stated that the object was larger than a conventional aircraft. The object was observed for approximately 30 minutes (Berline, Dan wilson)

At 11:55 p.m. CST, Capt. Eugene P. Daspit and T/Sgt James E. Hansen sighted an unusual object on the PPI scope of an AN/CPS-5 radar set at Keesler AFB, Mississippi. The radar target was teardrop shaped and was first sighted at an azimuth of 335 degrees approximately 43 miles distant. The target moved very slowly south for approx. two minutes, then it stopped for approx. four minutes. It then began to move slowly north for three minutes, then stopped for two minutes and disappeared. After approx. three minutes the target reappeared and began moving north at a more rapid pace and disappeared completely at a distance of 50 miles from the radar site. (Dan Wilson)
