Kelly Johnson and the U-2

Joel Carpenter:

The UFO Incident
On December 16, Johnson and his wife Althea were visiting their Lindero Ranch near Agoura, California, which was situated on a hillside facing the coast not far from Pt Mugu Naval Air Station, an aircraft and missile test facility. At about 5 PM Johnson was looking through a window at the brilliant sunset when he noticed a dark elliptical shape in the sky in the direction of Pt Mugu cape. His first thought was that it was a lenticular cloud, or possibly a smoke trail from an aircraft, but it remained stationary and unchanged for several minutes. He called for Althea to bring him his 8-power binoculars and ran outside. By that time the object had begun to move, accelerating away from him in a shallow climb in a direction opposite to the motion of the other clouds in the sky. It seemed to be very large and distant, and moving fast, but he had no real way of knowing its actual size, distance or speed.

At the same time, coincidentally, a Lockheed airplane was in the air on a test flight along the Los Angeles coastline. Constellation airframe 4301 was the prototype for a Navy Airborne Early Warning (AEW) aircraft, the WV-2 Warning Star. The WV-2 was a large four-engine transport equipped with huge blisters housing radar antennas (a search radar unit in the belly and a height-finder in a dorsal fairing), and was designed to fly very long standing patrols far off the coasts of North America to provide long-range detection of incoming Soviet bombers. Constellation 4301 was the first of a long line of Navy WV-2s and Air Force EC-121s that would provide a vital part of the North American air defense network throughout the 1950s and '60s.

At the controls of the Warning Star were Rudy Thoren and Roy Wimmer, both highly experienced senior test pilots in the Constellation program, assisted by Joseph F. Ware, Jr, another longtime Lockheed engineering test pilot.[3] Also in the cockpit were Charlie Grugan, another veteran company pilot, and Lockheed's Chief Aerodynamicist, Philip A Colman. It was customary for Lockheed engineers to ride aboard their planes during test flights, and Johnson himself often did so. (There are no indications that the elaborate radar systems, which required a crew of at least a dozen men, were active during the flight.)

Thoren had been recruited by Johnson from their alma mater, the aeronautical engineering school at University of Michigan, and had been Chief of Flight Test for Lockheed since 1946, in charge of all the company's test pilots. Colman was a Cal Tech graduate who had made valuable contributions to the P-38 program, and who would soon be tasked by Johnson with designing the wings for the new CL-282 recon plane. All of the crewmen were top representatives of their fields, having flown for the company for years in development programs of a variety of sophisticated aircraft.

The exact purpose of the test flight is not detailed in the sighting reports, but such flights typically involved calibration of airspeed vs engine power settings at various altitudes, and therefore the crewmen were very conscious of the height of the aircraft. Altitude recording instruments were carried on board.

Though Wimmer was technically the pilot in command, he had turned the controls over to Thoren and was maintaining a watch for other air traffic as Thoren conducted his tests. They had turned from a southeast heading to west, just off the coast of Long Beach, when, at 4:58 PM, Wimmer noticed a dark shape ahead at about their altitude of 14,000 feet. After watching it for a few moments and noting that it was not moving, he jokingly pointed it out to Thoren, saying "Look out, there's a flying saucer." Thoren turned the WV-2 a bit to the right to head toward the object. The other men saw the object too and watched it for a few minutes with a growing sense of curiosity. It appeared to be a very large aircraft of some type, but as it remained stationary and unchanged in shape over at least a five minute period, they became more and more intrigued. Thoren finally diverted from his course and headed directly at it. They flew toward it at about 225 mph for some time without appearing to gain on it at all. Then Wimmer, who was less occupied with piloting tasks and was able to keep a constant watch on the object, commented that it seemed to be disappearing. Within a few moments it appeared to head west directly away from them at high speed, remaining dark and solid-looking the entire time as it dwindled to a tiny dot. They all felt that it was a large object at a considerable distance, and compared its size to the largest types of transport or bomber aircraft. The men later reported that they thought little more of the incident at the time due to their preoccupation with completing the test mission, but Thoren was intrigued enough that upon returning home that evening he told his family about the sighting and sketched the object.

The following day, Kelly Johnson had returned to work and was discussing the WV-2 test flight with Thoren, who was still ruminating on the incident. A bit worried that Johnson would ridicule him, the pilot casually mentioned the sighting. Thoren was surprised when Johnson excitedly interrupted him and described his own sighting in detail. Both concluded that all the witnesses had been viewing the same object at the same time. Over the course of the next few weeks each of the pilots wrote a detailed personal account of the case, probably at Johnson's urging, and the Chief Engineer, in his typical meticulous style, assembled them into a file (Lockheed file LAC/149536) and drafted a personal cover letter addressed to the "Air Force Investigation Group on Flying Saucers" at Wright Field. Then, tough and combative as he was, Johnson hesitated to send the report. After all, he was hoping to get a foot in the door of the Air Force's new covert strategic reconnaissance aircraft competition and was very concerned that a UFO report might jeopardize his credibility. He may have sought the advice of his friend, Lt General Donald Putt.

General Putt's Involvement

Putt receives his second star from Gens Craigie and Doolittle

ARDC commander Putt, who had the responsibility for reviewing and approving new Air Force reconnaissance projects like Johnson's CL-282, had also had a long, if intermittent, association with the UFO problem. A former test pilot with a solid Cal Tech engineering background, Putt was one of the stars of the Air Force, having risen to prominence as project officer for the B-29 bomber during WWII. Closely allied with Theodore von Karman's Scientific Advisory Board (he would be its military supervisor for several years), Putt had helped make science and advanced technology the backbone of the emerging air service. He had been commander of T-2 Air Intelligence during a crucial period following the end of hostilities in Europe and had been a strong backer of Operation Paperclip, the transfer of German aeronautical scientists to Wright Field. A widely-respected, politically savvy officer, Putt showed little evidence of the antipathy to UFOs that many other Air Force generals exhibited. In December 1948 Project RAND missile expert James Lipp had written a paper at Putt's request that examined the possibility that UFOs were extraterrestrial spacecraft that used propulsion principles comparable to known or foreseeable rocket technology. (The fascinating paper was published as an appendix to the final report of Project SIGN.)

Just months before the Lockheed UFO incident, Putt had visited the plant of Avro Aircraft Limited in Toronto, Canada, where he had seen a full-scale engineering mockup of an advanced, supersonic saucer-like aircraft, "Project Y," that had been conceived by a group of ex-British engineers.

Avro Project Y mockup

He was impressed enough by the design that ARDC would begin to fund its development within the year. The Project Y vehicle was a virtual replica of Kenneth Arnold's initial June 1947 sketches of a "spade-shaped" UFO, probably because the Avro craft's chief designer was an avid collector of UFO data and considered Arnold's report to be reliable. The Project Y machine, which had been under development since the fall of 1951, was somewhat similar to Nathan Price's 1952-3 concept, and like the Lockheed saucer was intended to be able to take off vertically, hover in midair, and climb to extreme altitudes at incredible speeds. It seems likely that Lockheed, having originated one of the most sophisticated saucer-like aircraft concepts to date, would have been aware of the the Avro design prior to the UFO incident.

See: Project Ladybird

In any case, Putt's visit to Avro was no secret. It was featured prominently in US newspapers, particularly in the New York Times. In two articles, one in September, at the time of the trip, and another in early October, the Times discussed Putt's interest in the Avro VTOL disc. Perhaps a more important indicator of the effect of Putt's Avro visit was Project Blue Book's Report 12, which was issued about eleven weeks before the Lockheed UFO incident. Report 12 devoted several pages to a somewhat garbled history of the Avro project and its designer's attempts to interest the US in the concept. The report noted that the Avro engineers believed that the Soviets were responsible for many UFO reports, and that Red saucers were being launched from submarines off the North American coasts on surreptitious overflights of the US. Avro, Report 12 said, wanted to install their saucer in submarines too.

Oddly enough, an article touting Putt's positive comments about the Avro saucer appeared in the December 16 edition of the magazine "People Today" -- the very day of the Lockheed sighting.

Putt clearly made his views on the Avro saucer known within the Air Force as well. On December 29, Maj Gen John Samford, Air Force Director of Intelligence, memoed Col George L Wertenbaker, ATIC chief, on the Avro program.

It is my understanding that you are continuing an active interest in the 'Flying Saucer' being developed by the Canadians. Also, you may have knowledge of General Putt's reaction to their program from his recent trip to that country. I would appreciate your analysis of this Canadian program. There is also an interest from both the possibility standpoint, and the time factor required by a foreign country to achieve results in this field. If you so desire, we might be able through our contacts with the Canadians here, to arrange ATIC representation during this development, or phases thereof.
Kelly Johnson had close personal and professional ties with Putt and officers like him, and it's likely that some time in early 1954 the two discussed the UFO sighting. Putt also received a copy of the formal Lockheed sighting report from the company via some unnamed intermediary. The general understood Johnson's concerns about the credibility problems a UFO report would cause, and forwarded the file to Col George Wertenbaker at the Air Technical Intelligence Center at Wright-Patterson AFB in mid-February with personal cover letter.

"This report was handed to me by Lockheed personnel," Putt informed Wertenbaker,

with the explanation that Mr. Johnson was most reluctant to write the report in the first place and then refused to forward it on to you because of his belief that those who profess to have seen flying saucers are not usually considered to be logical and practical hard-headed engineers. However, I thought you should have the report for whatever value it may be in your overall studies.

Putt's intervention would seem to have guaranteed that the incident would be taken seriously. Nevertheless, the eventual official Blue Book evaluation was that the object was just a lenticular cloud.

The Case File and Its Implications

Although the sighting was not highly dramatic in comparison to many UFO reports, what makes it particularly unusual - and scientifically useful - is that it was a long-duration daylight sighting of an object seen by two independent groups of observers. Moreover, these groups - one stationary and one moving - were separated by very long baselines in both horizontal and vertical planes, facilitating triangulation of the object's position. One group even had the advantage of using optical instruments to view the UFO. Unlike many sensationalized UFO events, these observations were recorded in a calm, professional manner by the witnesses themselves while the details were still fresh in their minds. No media attention was sought or desired. And most importantly, the integrity and competence of this particular group of observers is almost unquestionable. A more qualified set of eyewitnesses would be hard to imagine.

Because of their precise observations and careful documentation of the incident, a great deal of information can be extracted from the account. Available weather data makes it clear that Blue Book's rubber-stamp identification of the object as a lenticular cloud is untenable...and therefore the object's identity is still a mystery.

There was no question in about this in Kelly Johnson’s view. He was absolutely certain that it was no cloud, aircraft or other mundane object.

The case file reveals a multitude of intriguing threads, including references to prior sightings by several of the engineers. Johnson furnished two signed sketches with his report. One showed the December 1953 object, a simple flattened ellipse, but the second, dated "about November 1951," shows a strange object resembling a rounded, sweptback flying wing aircraft. In his written account, Johnson elaborates:

I should also state that about two years ago Mrs. Johnson and I saw an object which I believed at the time, and still do, to be a saucer, flying west of Brents Junction, California, on a very dark night. I did not see the object itself but saw a clearly defined flame or emanation, as shown on the attached sketch. This object was traveling from east to west at a very high speed and with no noise. The flame or emanation was a beautiful light blue, having extremely well defined edges. My first impression was that it was an afterburning airplane, but the lack of noise and the pure spread of the flame eliminated that possibility completely.
(Brents Junction is a small town just east of Johnson's Agoura ranch.)

Roy Wimmer mentioned in his report that he had seen mysterious lights over Santa Catalina Island sometime in 1951 or 1952 during a flight in Constellation 1961S, the original prototype of the Constellation line.

Joseph Ware reported that he had previously visited a group of UFO enthusiasts at Giant Rock. While he does not specify the group by name, it seems clear that this is a reference to contactee George Van Tassel and his followers. Van Tassel had been a mechanic for Howard Hughes, who was, via his airline TWA, the original customer for the Constellation airliner. Van Tassel had later worked directly for Lockheed on the Constellation program and it's almost a given that the Constellation test crew on board the WV-2 during the sighting would have known him.

For better or worse, Lockheed's contactees lurk in the background of the Johnson sighting. The likelihood is high that Johnson at least would have been aware of Van Tassel's beliefs and activities, and probably considered that ridicule aimed at the Giant Rock group could easily have spilled over onto his own sighting and onto the Skunk Works itself. This may explain the fact that his sighting report file was held back from ATIC and only reached Putt through a "back channel."

The most fascinating single point in the file is its clarification of Kelly Johnson's opinions on UFOs. Far from sharing the skeptical attitude that Hall Hibbard displayed in 1947, Johnson reveals himself to be committed to UFO reality:

I should state that for at least five years I have definitely believed in the possibility that flying saucers exist - this in spite of a good deal of kidding from my technical associates. Having seen this particular object on December 16th, I am now more firmly convinced than ever that such devices exist, and I have some highly technical converts in this belief as of that date.
What happened circa 1948 to make Johnson a believer? Was he given intelligence briefings that convinced him? Had he spoken to reliable pilots who had had persuasive sightings? Had he heard of Project SIGN's legendary Estimate of the Situation that concluded that flying discs were extraterrestrial? Had CIA's Phil Strong used Johnson as an unofficial consultant or sounding board on UFO-related issues? [4] Since he felt that it was important to document the sighting and ultimately forward a report to the Air Force (in spite of any embarrassment it might cause himself or Lockheed), Johnson obviously was aware of the existence of an Air Force UFO investigation project, but he clearly was not intimately familiar with it, since his report is generically addressed to an "Air Force Investigation Group on Flying Saucers," rather than to Project Blue Book by name.

It is worth noting that Johnson does not specifically state that he believed in the extraterrestrial origin of these "devices." But it seems clear that he regarded them as vehicles of some type, and certainly their performance was beyond that of any known or foreseeable manmade craft - even Avro's or Lockheed's own super-saucer concept.

Another unanswered question is what effect that Johnson's sighting may have had on his peers in the military and the intelligence community. Given Johnson's stature, such a report must have given the most UFO-phobic skeptics pause, and in fact there are indications that Johnson made many of his closer associates aware of the incident over the years.


Johnson's formidable political and engineering skills overcame any negative effects the sighting may have had on his reputation, and even though the Air Force did reject his modified XF-104 reconnaissance aircraft concept, he was victorious in the end when, in late 1954, he was awarded a contract for a developed version of the CL-282 by the CIA. Code named AQUATONE, but known to Johnson's Skunk Works design group as the "Angel," the glider-like jet (later designated "U-2") would begin test flights at Nevada Test Site Area 51 in August 1955. Soon, according to the official CIA history of the AQUATONE program, the U-2’s gleaming sunlit surfaces would begin generating dozens of high-altitude UFO sightings, particularly among airline pilots on the Chicago-Los Angeles routes. The CIA's history asserts that the U-2 itself was thus responsible for "over half of all UFO reports" of the 1950s. [5]

AQUATONE number 1 at Area 51, July 1955

Lear Electronics, a company owned by another aviation legend, William Lear Sr, built the crucial autopilot for the AQUATONE. By the 1980s, Lear's son John would be promoting stories concerning the existence of alien spacecraft being stored, or even flown, at Area 51. Some of the early versions of these tales claimed that these UFOs were being operated by Lockheed under the code name REDLIGHT.


And in fact, in the 1970s, when the Skunk Works, under its new head, Ben Rich, began studying methods of drastically reducing the radar cross-section of aircraft, its engineers had toyed with saucer-shaped designs. Stymied by the non-aerodynamic faceted surfaces dictated by the electrical engineers who were responsible for finding ways to scatter radar waves from the airplane's skin, some Skunk Works old timers pondered even more exotic forms. "Several of our aerodynamics experts," Rich recalled,

including Dick Cantrell, seriously thought that maybe we would do better trying to build an actual flying saucer. The shape itself was the ultimate in low observability. The problem was finding ways to make a saucer fly. Unlike our plates, it would have to be rotated and spun. But how? The Martians wouldn't tell us.
But the irony becomes even richer, straining credibility. About the time of the December 1953 sighting by Johnson and his test pilots, Lockheed had won a contract from the Naval Research Laboratory to modify a WV-2 with a new, advanced AN/APS-82 radar that would enable air targets to be more easily detected in high sea-clutter states. The new antenna's size - 17.5 feet wide - was such that it was initially thought that it could not be accommodated on an aircraft (one concept was to place it in an airship) but Lockheed’s engineers, beginning their design work in January 1954, had devised a unique solution. Wind tunnel tests demonstrated that a properly-shaped rotating fairing could provide enough lift to nearly offset the weight of the antenna system. An 18,000 lb lenticular "rotodome" some thirty feet in diameter -- the first of its kind -- was installed on a WV-2 that was retained by Lockheed as an experimental model. It was the same aircraft, Constellation airframe number 4301, that had been involved in the December 1953 UFO sighting. The WV-2E made its first flight with the saucerlike fairing in August 1956.

The shape of the rotodome (which had a strong resemblance to Price's supersonic saucer design), probably combined with company lore about the UFO incident on the WV-2 (and maybe Van Tassel and Angelucci too), proved too much for Lockheed's engineers, and just before the dome was installed on the aircraft, they decided to have a bit of fun by using it as a prop in a saucer spoof photo.

The photo lacks clarity, but a small entity appears to be emerging from a hatch atop the dome. He waves to the eager Lockheed technicians...


[1] The Lockheed case came to my attention through a reference in Mike Hall's and Wendy Connors' book "Summer of the Saucers." Hall and Connors, in turn, had learned of it from one of veteran UFO historian Loren Gross's invaluable monographs. I was intrigued by the unusual sketch of the UFO that accompanied the report and was curious as to which Lockheed engineer was responsible. The Hall-Connors version of the story was drawn from the "sanitized" Blue Book files released to the public in the 1970s in which the identities of the witnesses had been obscured. Mike Hall kindly provided the Blue Book microfilm roll containing the file. Mary Castner of CUFOS gave indispensable assistance in this project, and Brad Sparks's encyclopedic knowledge of the CIA's interaction with UFOs, FOIA releases and general UFO history led to recovery of unsanitized versions of the Blue Book case file which contained vital information. This article would not exist without their outstanding cooperation.

[2] Extensive declassified documentation on CIA's interaction with UFOs makes it clear that Phil Strong was the Agency's point man on the issue as late as 1962. While Pocock states that he considers it unlikely that Strong was Johnson's source of information concerning the Air Force reconnaissance project (and other Lockheed officials already knew of it), senior CIA official Robert Amory recalled that this was the case. In any event, Johnson clearly had close ties with Strong, who was moving in rather interesting circles. Strong had links with strategic reconnaissance studies such as the 1952 MIT/Lincoln Laboratory "Beacon Hill" project and the reconnaissance panel of the USAF Scientific Advisory Board. At the same time, he was involved with CIA's Office of Scientific Intelligence UFO research. See http://www/foia.ucia.gov/

[3] Wimmer and Ware would be crew members on early flights of another famous Lockheed product, the C-130 Hercules, in 1954.

[4] According to a former senior aerospace management official who knew Johnson, USAF Chief of Staff General Hoyt Vandenberg had given a briefing to the heads of the major aviation companies circa 1948 in which he emphasized the Air Force’s continuing concern with UFOs and its ongoing investigation of reports.

[5] To UFO researchers, who know of tens of thousands of sighting reports, this controversial claim seems absurd on its face, but it may be a matter of semantics and perspective. Former CIA photo analyst Dino Brugioni states that he was one of the liaison points between the U-2 program and Air Force UFO investigators. Brugioni claimed that airline pilot reports that might have been stimulated by early U-2 development flights in the Nevada area circa 1955-6 were referred to him by certain AQUATONE-cleared Air Force personnel. He would check flight plans and inform the Air Force investigators of probable "hits." From CIA’s point of view, many UFO reports that it learned of via this highly selective channel were caused by the U-2.
