Flying Saucers Part 1 (1898 to 1970)
It is possible to write a history of flying saucers without recourse to telepathic contact with aliens, crashed alien craft or indeed any extraterrestrial influence whatsoever. This time line looks at the origin of disc shaped aircraft and the subsequent media campaign to have us all associate a particular shape of aircraft with extraterrestrial technology. Jan Aldrich's Project 1947 website  and the Grey Falcon  website have more in depth information for those who are interested.
The idea of a flying disc in modern history dates back at least to 1898 when, on June 14, F.A. Jone was granted US patent 605579 for a disc shaped flying machine. From the relative size of different parts of the aircraft the design is estimated to be at least 60 feet high. There's no record that Jone ever got his design off the drawing board and into production, but humanity did not have to wait very many years to witness the first disc shaped aircraft get off the ground. 
According to the Smithsonian Institution and Fédération Aéronautique Internationale (FAI), the Wright brothers made the first sustained, controlled, powered heavier-than-air manned flight at Kill Devil Hills, North Carolina, on December 17, 1903. Six years later Charles Voight's Umbrella, a disc shaped aircraft which he made with McCormick-Romme first flew on March 11, 1910. 
The first experimentation with what we might recognise as a flying saucer was performed by a Rumanian aeronautical engineer named Henri Coandă who was granted a French patent related to the Coandă Effect in 1934. During early 1930 he used the same principle as the basis for the design of a disc-shaped aircraft called Aerodina Lenticulara, a flying saucer that used an unspecified source of high pressure gases to flow through a ring-shaped vent system. In 1936 Coandă applied for a patent for his design. No practical full-scale version was built. 
In 1939, Josef Andreas Epp designed a radical rotor/jet powered aircraft he named the Helioplane, but this design could not be pursued due to limitations imposed due to the early development phase of the German turbojets of Heinkel, BMW, and Junkers. 
In 1940 an Austrian inventor named Viktor Schauberger built the first Repulsine (flying saucer based on the Coandă effect) initially in Berlin and then in Vienna, where the prototype reportedly broke from its mooring and smashed through the factory's ceiling.  The early results of Schauberger’s work with the Repulsin was reported to aircraft manufacturer Heinkel Flugzeugwerke (Heinkel) for the purpose of exploring the possibility of adapting the discoid motor to aircraft.  
During 1941 one of Heinkel’s personnel named Rudolf Schriever came up with the idea of a “Flugkreisel” (Flight Gyro) that did not rely on Schauberger’s discoid motor but on developing turbojet technology. Schriever later claimed that the inspiration for his design originated with the discus sporting event observed by him at the 1936 Olympics; but this is doubtful given that his employer Heinkel was researching the Schauberger motor the same year as Schriever’s idea came to him. Schauberger continued work on perfecting the Repulsin at Mauthausen along with 20-30 prisoner engineers. 
Schriever's Flugkreisel was a large disc-fan of 20 meters diameter with 21 rotor blades that surrounded a hemispherical cockpit. Attached to the underside of the of the disc rotor were three jet engines that spun the rotor like a helicopter for vertical take off. Two other lower body jets were attached to each side allowing the disc to achieve level flight. In Schriever’s drawings the jets were powerful kerosene burning jet turbines. 
Dr. Richard Miethe also worked with Rudolf Schriever on German saucer technology. One design which Bruno Schwenteit patented postwar was claimed to be the Miethe-Schriever disc so often labeled the mystery V-7. Schwenteit also claimed the disc was actually constructed during World War II but no photographic evidence has surfaced to prove that. 
In November 1942 the doors of the Vought hangar opened and test engineers trundled out a saucer-shaped aircraft on two long, stilted legs. It was called the V-173 and was designed by an aeronautical engineer who had been active in National Advisory Committee for Aeronautics (NACA) research and had recently joined the staff of Chance Vought: Charles H. Zimmerman. 
Josef Epp continued trying to develop a flying disc. Epp traveled to Prague where BMW was testing out their small-scale disc-fan Flügelrad (Winged Wheel) jet auto-gyros which utilized the company’s BMW 003 series engine with a Strahlrohr (Jet Pipe) deflector system to divert engine thrust up to the spinning rotor blades, a combination rotor-jet idea that originated with Rudolf Schriever’s 1941 Flugkreisel. Epp designed, by 1943, his Omega Diskus which combined ducted fan technology with two free-spinning rotors propelled by Pabst ramjets being developed for the Fw Triebflügel (Thrust Wing) and utilizing the increased lift of the Coanda Effect. The Omega Diskus consisted of a circular cockpit 4 meters in diameter surrounded by a disc wing of 19 meters diameter. The wing supported eight ducted lift fans of 80 hp each. The engines were held in place by eight conical pipes of 3 meters diameter. 
In 1944 Victor Schauberger was drafted into the SS and ordered (on pain of death) to develop an improved Repulsine and a submarine engine for Germany's war effort, at the Mathausen concentration camp. All prototypes and working models of the Repulsine were subsequently ordered by Field Marshall Keitel to be destroyed on the collapse of the German armies. 
Alexander Weygers filed his Discopter patent in the US on January 1, 1944. The discopter was a vertical lift off aircraft that looked very much like a flying saucer. Weygers made numerous detailed drawings of the aircraft and other drawings of an American city with many discopter ports. He sent these detailed plans to all the branches of the U.S.. Military and was eventually told that they were intrigued by the concept and the design of the craft but were not prepared to work on it at that time because the war effort superseded its development. 
In early 1944 German Arthur Sack completed his first piloted Kreisflügler circular wing design 'aircraft', which has since been designated the Sack AS 6 (or the Sack AS 6 V1). Sack persuaded the Kommandant of his local airfield to allow some developmental work to go on at the facility. It is doubtful whether the Sack AS 6 ever got airborne, other than a short hop, since it was clear that the 'aircraft' was under-powered. 
On August 1, 1944 J. K. Northrup et al filed US patent No. 2412646 for a tailless aircraft (or flying wing) of very similar design to the Horten 229, which was under development in Germany towards the end of the war. The Northrup flying wing was powered using propellers where as the Horton 229 had jet engines. 
Schriever’s Flugkreisel was transferred to Prag-Kbley where BMW was testing out the Flügelrad models. Georg Klein claimed to have seen the strange craft at the aerodrome in 1945 and his description of a large disc-fan powered by 5 jet engines that produced a tremendous roar supports his claim. None of the BMW Flügelrads were powered by 5 jet engines and none were located anywhere on the Flügelrads except inside the disc body. It is claimed that in February 1945 the Flugkreisel attained a top speed of 1,300 mph and a climb to 45,000 ft in two minutes! The Flügelrads by comparison could barely get off the ground, were highly unstable, and made frequent "hard” landings. Only one BMW Flügelrad II V-2 (or V-3) finally achieved powered level flight in April 1945 just before all the Flügelrads and Schriever’s Flugkreisel were destroyed in the Russian advance. 
According to the Augsburger Neue Presse (Augsburger New Press) dated May 2, 1980 Ing. Heinrich Fleissner is the “Father of the Flying Disc” having designed at Peenemünde a disc known as the Düsenscheibe (Nozzle/Jet Disc) that took to the air shortly before Germany capitulated, on April 24, 1945 from Berlin-Lichtenfeld.
The end of World War II saw Nazi Germany's many technological secrets plundered by the Russians, Americans and British. In May 1945, a Russian intelligence team removed Viktor Schauberger's research papers and models from his Vienna flat. He was held for a month (or months according to different accounts) in protective custody by American intelligence forces who decided he was not to be deported to the USA. Schauberger subsequently started work on his Klimator, for domestic air conditioning. 
The image below is an English translation of a Greek newspaper article, which was presented in a 1953 CIA memo. It describes the fate of flying saucer prototypes and plans at the end of the war 
US intelligence and military services brought German scientists to the US during and after the final stages of World War II. German records were originally falsified under the title Operation Overcast, which was subsequently renamed Operation Paperclip. Once “bleached” of their Nazism, the US Government granted the scientists security clearance to work in the United States. Many of the Nazi aeronautical specialists went to work at Wright Field, Ohio. 
Paperclip records show that the Horten Brothers were released by the U.K. for exploitation and allocated to the U.S. on 15 November 1946 
Just prior to their capture the Horton Brothers had been working on the design for a new generation of circular-shaped vertical-takeoff aircraft. Records also indicate that after the war, models of the Horten's designs were tested in the wind tunnel at Wright Field, now Wright-Patterson Air Force Base. 
The photograph below is of the Horten prototype of the first flying wing powered by jet engines. With its radar-absorbing carbon impregnated plywood skin and swept-back single wing, the 1944 Ho 229 was designed to be invisible to radar and was arguably the first stealth aircraft. The US military made one available to Northrop Aviation, the company which much later used a flying wing design for the B-2 stealth bomber. 
A 1945 report on airplanes designed by Germany's Horten brothers included this photograph of an unusually shaped parabolic aircraft. 
Shortly after the war Major-General Hugh Knerr, deputy commander of the US Air Force in Europe, wrote: "Occupation of German scientific and industrial establishments has revealed the fact that we have been alarmingly backward in many fields of research. If we do not take the opportunity to seize the apparatus and the brains that developed it and put the combination back to work promptly, we will remain several years behind while we attempt to cover a field already exploited." 
In 1945 Roy Fedden (British chief of the technical mission to Germany for the Ministry of Aircraft Production) remarked: "I have seen enough of their designs and production plans to realize that if they (the Germans) had managed to prolong the war some months longer, we would have been confronted with a set of entirely new and deadly developments in air warfare." Fedden also added that the Germans were working on a number of very unusual aeronautical projects, though he did not elaborate upon his statement. 
The Central Intelligence Agency was created by Congress with the passage of the National Security Act of 1947, signed into law by President Harry S. Truman. 
Mechanix Illustrated, May 1947, carried an article on the V-173 entitled The Flying Flapjack. The article described the V-173's almost vertical take capability and its ability to fly at very low speeds and very high speeds and claimed it should be possible for the aircraft to hover. 
On 24 June 1947, when Kenneth Arnold, a private pilot and reputable businessman, while looking for a downed plane sighted nine flying objects near Mt. Rainier, Washington State, traveling at an estimated speed of over 1,000 mph. Arnold evoked images of "saucers skipping on water" to describe how they flew through the air, but a local newspaper misquoted him, and the term "flying saucer" was born. 
Arnold's report was followed by a flood of additional sightings, including reports from military and civilian pilots and air traffic controllers all over the United States. As shown below, the objects Arnold described look an awful lot like the Horten 229, which was brought to the US from Nazi Germany in 1945.
On July 8, 1947, the Roswell Army Air Field (RAAF) public information officer Walter Haut in Roswell, New Mexico, issued a press release stating that personnel from the field's 509th Bomb Group had recovered a crashed flying disk from a ranch near Roswell, sparking intense media interest. The next day, the press reported that Commanding General of the Eighth Air Force Roger M. Ramey stated that, in fact, a radar-tracking balloon had been recovered by the RAAF personnel, not a flying disc. A subsequent press conference was called, featuring debris said to be from the crashed object, which seemed to confirm the weather balloon description. The incident was forgotten and almost completely ignored, even by UFO researchers, for more than 30 years. 
Due to his expertise in low-aspect aircraft design—similar to the flying disk or flying saucer shape of many reported UFOs in the summer of 1947 Alfred Loedding, a civilian engineer from Wright Field, became the focus of early informal Air Force UFO reports, serving as liaison between The Pentagon and Air Force officers Howard M. McCoy and William R. Clingerman. 
The following passage is taken from the book Alfred Loedding and The Great Flying Saucer Wave of 1947 by M.D.Hall and W.A.Connors
For the best part of the summer of 1947 most serious minds studying the flying disc mystery, like Alfred Loedding, considered that a domestic secret project might account for the sightings. After eliminating that possibility, the foreign origin option was exhaustively explored. By 1948 foreign origin became a catch word for visitors from outer space, but in 1947 it meant only one thing—Russians. In fact, worries that the Soviet Union may have gleaned a Nazi super weapon at the end of the Second World War remained in the minds of Air Force officials up through 1952. But by late 1947 some aeronautical engineers, like Alfred Loedding, began to consider that "flying saucers" may represent intelligently controlled machines from another world. 
M.D.Hall and W.A.Connors would have us believe that a man working at Wright Field, where the Nazi aeronautical experts were also working, came to the conclusion that flying discs were more likely from outer space than descendents of the prototype flying discs already built in Nazi Germany. What are the odds? Aliens show up from another world in disc shaped craft immediately after German scientists manufacture prototypes on earth and the man who comes to this conclusion just happens to be a flying disc designer working at the same air force base as the experts who built the German discs. Loedding obviously thought the aliens were onto a good thing because he filed his own patent (US patent 2619302)  for a "Low Aspect Ratio Craft" in on 25 August 1948.
From 1948 to 1949, Loedding was a member of Project SIGN (initially named Project SAUCER), which was set up on 23 January 1948, by Air Force General Nathan Twining of The Technical Intelligence Division of the Air Material Command (AMC) at Wright Field to collect, collate, evaluate, and distribute within the government all information relating to UFO sightings, on the premise that UFOs might be real and of national security concern. The Air Force report found that almost all sightings stemmed from one or more of three causes: mass hysteria and hallucination, hoax, or misinterpretation of known objects. Nevertheless, the report recommended continued military intelligence control over the investigation of all sightings and did not rule out the possibility of extraterrestrial phenomena.
Donald Keyhoe's article Flying Saucers Are Real appeared in the January, 1950 issue of True (published December 26, 1949)  and caused a sensation. The article began as follows:
IT WAS A strange assignment.
I picked up the telegram from my desk and read it a third time.
NEW YORK, N. Y., MAY 9, 1949
HAVE BEEN INVESTIGATING FLYING SAUCER MYSTERY. FIRST TIP HINTED GIGANTIC HOAX TO COVER UP OFFICIAL SECRET. BELIEVE IT MAY HAVE BEEN PLANTED TO HIDE REAL ANSWER. LOOKS LIKE TERRIFIC STORY. CAN YOU TAKE OVER WASHINGTON END?
...and the article concludes:
But even if all the evidence--the world-wide sightings, the old records, the Chiles-Whitted and other cases--should be completely ignored, Americans cannot escape eventual contact with dwellers on other planets. Even though space visitors never attempt contact with us, sooner or later earthlings will be traveling to distant planets--planets that scientists have said are almost surely inhabited.
The American people have proved their ability to take incredible things. We have survived the stunning impact of the Atomic Age. We should be able to take the Interplanetary Age, when it comes, without hysteria.
Though such figures are always difficult to verify, Captain (U.S. Air Force), Edward J. Ruppelt, the first head of Project Blue Book, reported that "It is rumored among magazine publishers that Don Keyhoe's article in True was one of the most widely read and widely discussed magazine articles in history."
The vast majority of Americans would never suspect that their government wages psychological warfare on its own people in order to convince them that aliens are visiting earth in flying saucers, but the evidence overwhelmingly supports this being the case. The situation continues to the present, in an 18 December 2009 article Popular Mechanics noted: "The idea of flying saucers has been around since the 1940's. Since then, many depictions of alien spaceships (and of aliens themselves) have been eerily similar, even as they evolve with the times." 
According the the CIA website: 
Amid mounting UFO sightings, the Air Force continued to collect and evaluate UFO data in the late 1940s under a new project, GRUDGE, which tried to alleviate public anxiety over UFOs via a public relations campaign designed to persuade the public that UFOs constituted nothing unusual or extraordinary. UFO sightings were explained as balloons, conventional aircraft, planets, meteors, optical illusions, solar reflections, or even "large hailstones." GRUDGE officials found no evidence in UFO sightings of advanced foreign weapons design or development, and they concluded that UFOs did not threaten US security. They recommended that the project be reduced in scope because the very existence of Air Force official interest encouraged people to believe in UFOs and contributed to a "war hysteria" atmosphere. On 27 December 1949, the Air Force announced the project's termination."
On 27 March 1950 the German Neue Presse reported: "The Italian scientist Giuseppe Belluzzo, an expert in the field of rocket and artillery building, declared in the Giornale d' Italia, Flying Saucers had already been developed in Germany and Italy in 1942. They represented nothing supernatural and also did not come from Mars, but rather had been developed solely under rational application of the latest technical knowledge. Presently they would probably be shot down by any one of the great power for study purposes. The start could be similar to a torpedo launch, Naphta and Oxygen could serve as a propellant. Professor Belluzzo was Minister of Economy under Mussolini for a time. 
Rudolph Shreiver first went public with his involvment in flying disc development in a Der Spiegel article dated March 30, 1950 in which he described his projects which were not finished at the end of the war.
It is quite possible the saucer techonology progressed significantly in the years immediately proceeding World War II. Take for example the McMinnville, Oregon, photographs taken by Paul Trent on 11th May 1950. These are some of the best examples of a saucer photograph and extensive analysis has shown that this is one of the few UFO reports in which all factors investigated, geometric, psychological, and psychical, appear to be consistent with the assertion that an extraordinary flying object, silvery, metallic, disk-shaped, tens of meters in diameter, and evidently artificial, flew within sight of two witnesses. 
US patent 2,801,058 for a saucer shaped aircraft was filed by D.C. Lent on December 12, 1950. Air is drawn down in the centre of the craft and expelled outwards across the disc which is shaped identically to a conventional airplane wing. 
In 1951, Director of Central Intelligence, Allen W. Dulles, persuaded Cord Meyer to join the CIA. However, there is evidence that he was recruited several years earlier and had been spying on the liberal internationalist organizations he had been a member of in the late 1940s. According to Deborah Davis, Meyer became Operation Mockingbird's "principal operative". Operation Mockingbird was a secret Central Intelligence Agency campaign to control media by covertly putting journalists on the pay role. 
The Day The Earth Stood Still was released on 8 September 1951, the science-fiction classic was among the first to feature a flying saucer and it heralded a decade of copycat films . David L. Robb has now documented the Pentagon's direct control of Hollywood  and the appearance of flying saucers as craft from outer space appears to be a rather obvious front in the psychological war against the American people when viewed in the historical context of flying disc development.
The following 5 paragraphs are taken directly from the CIA website: 
With increased Cold War tensions, the Korean war, and continued UFO sightings, USAF Director of Intelligence Maj. Gen. Charles P. Cabell ordered a new UFO project in 1952. Project BLUE BOOK became the major Air Force effort to study the UFO phenomenon throughout the 1950s and 1960s.
CIA closely monitored the Air Force effort, aware of the mounting number of sightings and increasingly concerned that UFOs might pose a potential security threat. Given the distribution of the sightings, CIA officials in 1952 questioned whether they might reflect "midsummer madness.'' Agency officials accepted the Air Force's conclusions about UFO reports, although they concluded that "since there is a remote possibility that they may be interplanetary aircraft, it is necessary to investigate each sighting."
A massive buildup of sightings over the United States in 1952, especially in July, alarmed the Truman administration. On 19 and 20 July, radar scopes at Washington National Airport and Andrews Air Force Base tracked mysterious blips. On 27 July, the blips reappeared. The Air Force scrambled interceptor aircraft to investigate, but they found nothing. The incidents, however, caused headlines across the country. The White House wanted to know what was happening, and the Air Force quickly offered the explanation that the radar blips might be the result of "temperature inversions." Later, a Civil Aeronautics Administration investigation confirmed that such radar blips were quite common and were caused by temperature inversions.
Although it had monitored UFO reports for at least three years, CIA reacted to the new rash of sightings by forming a special study group within the Office of Scientific Intelligence (OSI) and the Office of Current Intelligence (OCI) to review the situation. Edward Tauss, acting chief of OSI's Weapons and Equipment Division, reported for the group that most UFO sightings could be easily explained. Nevertheless, he recommended that the Agency continue monitoring the problem, in coordination with ATIC. He also urged that CIA conceal its interest from the media and the public, "in view of their probable alarmist tendencies" to accept such interest as confirming the existence of UFOs.
Upon receiving the report, Deputy Director for Intelligence (DDI) Robert Amory, Jr. assigned responsibility for the UFO investigations to OSI's Physics and Electronics Division, with A. Ray Gordon as the officer in charge.Each branch in the division was to contribute to the investigation, and Gordon was to coordinate closely with ATIC. Amory, who asked the group to focus on the national security implications of UFOs, was relaying DCI Walter Bedell Smith's concerns.Smith wanted to know whether or not the Air Force investigation of flying saucers was sufficiently objective and how much more money and manpower would be necessary to determine the cause of the small percentage of unexplained flying saucers. Smith believed "there was only one chance in 10,000 that the phenomenon posed a threat to the security of the country, but even that chance could not be taken." According to Smith, it was CIA's responsibility by statute to coordinate the intelligence effort required to solve the problem. Smith also wanted to know what use could be made of the UFO phenomenon in connection with US psychological warfare efforts. 
Away from the CIA psychological warfare machine, in the issue of September 6 1952, the Italian weekly Tempo published the first of a four-part article devoted to the German secret weapons of World War II and signed by the Italian journalist Luigi Romersa (who already wrote an article in 1947 about an alleged German atomic test on the Baltic coast). The Tempo article was nearly the same as an article published in June 1952 by the French daily "France Soir" about the claims of Richard Miethe on his fantastic V-7. The article was originally published in the French magazine "La Marche du Monde", together with one picture of the alleged Miethe disc. More or less the same article was then reprinted on the French weekly "C'est la Vie" of August 7, 1952, where a second picture was presented. In Tempo magazine a set of three pictures was introduced as the visual proof of the German saucers flight-tested over the Baltic sea on April 17, 1944. The pictures are unfortunately blurred and no detail is visible. 
Swedish newspaper Aftonbladet, dated 10 October 1952, describes a German saucer built by Wernher von Braun (leading rocket scientist and Project Paperclip export) at Peenemuende, six meters in diameter, which lifted off in April, 1944. The article states that high fuel consumption was the major problem, a problem which would be solved utilizing atomic power. 
Back at the centre for psychological warfare on American citizens, the CIA website informs us: 
In January 1953, Chadwell and H. P. Robertson, a noted physicist from the California Institute of Technology, put together a distinguished panel of nonmilitary scientists to study the UFO issue. The Robertson panel's conclusions were strikingly similar to those of the earlier Air Force project reports on SIGN and GRUDGE and to those of the CIA's own OSI Study Group. All investigative groups found that UFO reports indicated no direct threat to national security and no evidence of visits by extraterrestrials. CIA officials said no further consideration of the subject appeared warranted, although they continued to monitor sightings in the interest of national security.
Nathan C. Price was an engineer and inventor for Lockheed aircraft. On January 23, 1953 he filed for a patent for a flying saucer. It was not granted until September 10, 1963 (patent number 3,103,324). 
Jack Frost of Avro Canada filed US patent 3062482 for a gas turbine engined aircraft on August 25, 1953 and it was not granted until almost a decade later on November 6, 1962. This aircraft was known as Project Y. 
The War of the Worlds, an academy award winner for special effects, was released on August 26, 1953 it was the first cinematic interpretation of the H.G. Wells novel about alien invaders from Mars and depicts saucer shaped alien craft. 
Fate Magazine, dated October 1953, include an article about Avro Canada's Project Y, which was funded by the US Air Force.  
Returning to the centre for lies and distortion, the CIA website informs us:
To most US political and military leaders, the Soviet Union by the mid-1950s had become a dangerous opponent. Soviet progress in nuclear weapons and guided missiles was particularly alarming. In the summer of 1949, the USSR had detonated an atomic bomb. In August 1953, only nine months after the United States tested a hydrogen bomb, the Soviets detonated one. In the spring of 1953, a top secret RAND Corporation study also pointed out the vulnerability of SAC bases to a surprise attack by Soviet long-range bombers. Concern over the danger of a Soviet attack on the United States continued to grow, and UFO sightings added to the uneasiness of US policymakers.
Mounting reports of UFOs over eastern Europe and Afghanistan also prompted concern that the Soviets were making rapid progress in this area. CIA officials knew that the British and Canadians were already experimenting with "flying saucers." Project Y was a Canadian-British-US developmental operation to produce a nonconventional flying-saucer-type aircraft, and Agency officials feared the Soviets were testing similar devices.
In November 1954, CIA had entered into the world of high technology with its overhead reconnaissance project. The Groom Lake test facility in Area 51 was established by the Central Intelligence Agency (CIA) for Project Aquatone, the development of the Lockheed U-2 strategic reconnaissance aircraft in April 1955. By August 1955 CIA was testing the U2 high-altitude experimental aircraft. A U-2 fleet under the control of the CIA began overflights of Soviet territory by mid-1956. It could fly at 60,000 feet; in the mid-1950s, most commercial airliners flew between 10,000 feet and 20,000 feet. Consequently, once the U-2 started test flights, commercial pilots and air traffic controllers began reporting a large increase in UFO sightings. The early U-2s were silver (they were later painted black) and reflected the rays from the sun, especially at sunrise and sunset. They often appeared as fiery objects to observers below. Air Force BLUE BOOK investigators aware of the secret U-2 flights tried to explain away such sightings by linking them to natural phenomena such as ice crystals and temperature inversions. By checking with the Agency's U-2 Project Staff in Washington, BLUE BOOK investigators were able to attribute many UFO sightings to U-2 flights. They were careful, however, not to reveal the true cause of the sighting to the public. 
The Report on Project Silver Bug, written in 1955 by the Air Technical Intelligence Center (ATIC) and Wright Air Development Center proposed the mounting of a research and development project into the building of a jet-propelled flying saucer, capable of both vertical takeoff and landing along with supersonic speeds up to 1,500 mph. If successful, the craft would have been based underground, thus avoiding the need for long runways and easily-distinguished bases which would have been easily taken out by a single nuclear bomb or missile warhead.  
An article featured in Look magazine dated June 14th 1955 (Volume 19) featured a design study for a flying saucer produced by Thomas Turner, an British aeronautical engineer with Republic Aviation Corporation. It would seem that Turner might have had some knowledge of Silver Bug if only because his proposal for a flying saucer was almost exactly the same as the ATIC aircraft. In addition Turner's proposal includes use of the Coanda effect and the placing of a pilot in a prone position in order to allow for high acceleration and quick turns . The article explained that persistent and fairly credible accounts claimed that A.V. Roe, Canada, Ltd., a Canadian aircraft manufacturer, had a saucer design under development since 1953. It had been abandoned since the cost factor was too high for the Canadians--over $75 million to get a prototype model into the air. 
On March 28, 1955 engineer, designer and technical advisor for the German Peenemünde saucer project, Heinrich Fleissner, filed a patent application with the United States Patent Office for a flying saucer. It was not granted until June 7, 1960.  it is on file today (Patent number 2,939,648)  The disc was never built, 0r if it was construction was never made public. 
Hollywood continued to push extraterrestrial origin of flying saucers. On June 1, 1955 This Island Earth was released, the film's creators used '50s-era eye-popping special effects to simulate a "death ray," a tractor beam and intergalactic travel. 
France developed a flying saucer with the help of French aerospace designer Rene Couzinet. It had a diameter of twenty seven feet but not too much is known about it. Pictures appeared in the Philadelphia Penn Inquirer on July 5, 1955 and it was apparently on display at the Farnborough Air Show in October of the same year.
Just after 7 P.M. on October 4, 1955, while on a train in the Transcaucasia region, US senator Richard Russell happened to gaze out a window to the south. To his considerable astonishment his eyes focused on a large disc-shaped object slowly ascending as a flame shot from underneath it. The object then raced north across the tracks in front of the train. Russell scurried to alert his two companions, who looked out to see a second disc do what the first had just done. At that moment Soviet trainmen shut the curtains and ordered the American passengers not to look outside.
Soon rumors about the senator’s sighting reached America, but when a reporter for the Los Angeles Examiner tried to obtain details, Russell said only, “I have discussed this matter with the affected agencies and they are of the opinion that it is not wise to publicize this matter at this time.” The report was not declassified until 1985. Interestingly, one of the “affected agencies” was not Project Blue Book, which never received the report. Apparently, the event was too sensitive for so lowly a project. 
The CIA tell us that they conclude Senator Russell saw an ordinary jet aircraft, but they lie all the time:
Adding to the concern was a flying saucer sighting by US Senator Richard Russell and his party while traveling on a train in the USSR in October 1955. After extensive interviews of Russell and his group, however, CIA officials concluded that Russell's sighting did not support the theory that the Soviets had developed saucerlike or unconventional aircraft. Herbert Scoville, Jr., the Assistant Director of OSI, wrote that the objects observed probably were normal jet aircraft in a steep climb. 
Royal Air Force Flying Review No.1 October 1955 recorded Rene Couzinet's flying saucer at the Farnborough Air Show.
In 1956 Captain Ruppelt, Chief of the US Air Force Project Bluebook said "When WWII ended, the Germans had several radical types of aircraft and guided missiles under development. The majority were in the most preliminary stages, but they were the only known craft that could even approach the performance of objects reported to UFO observers…" 
In the March 1956 Mechanix Illustrated  Willy Ley wrote an article entitled How The Flying Saucer Works "If you haven't seen saucers yet you will - and they'll be built to Air Force specifications". Illustration of directed airflow at the saucer edge to provide lift is identical to that shown in the June 155 Look Magazine article.
Mean while Hollywood continued to fill people's heads with interplanetary travelling flying saucers. Forbidden Planet was released on April fools day 1956, it is the first film in which humans pilot a flying saucer of their own design, the crew of United Planets Cruiser C-57D is sent to the planet Altair IV to investigate the disappearance of a colony of explorers. 
The groundbreaking flying-saucer effects for the cult classic Earth vs Flying Saucers were created by Ray Harryhausen, famous for his stop-motion animation in films such as Mighty Joe Young, a 1949 Academy Award winner for special effects, The Seventh Voyage of Sinbad and Jason and the Argonauts. 
Frank Tinsley proclaimed, in Mechanix Illustrated, March, 1957, "within 10 years you may be commuting by plastic saucer from your back yard"  as far as I can tell this article marks the final optimistic story about contemporary flying saucer development prior to the subject becoming either the subject of ridicule or science fiction. Perhaps this was the point in time at which saucer technology had been perfected and strict information control was implemented?
In the late 1950's the US military expected that their B-70 bomber's high operating speed and altitude would not make it immune from nuclear-tipped surface-to-air and air-to-air missiles. The proposed solution was the DAMS (Defensive Anti-Missile System). The DAMS would have to use an extremely fast and manoeuverable missile to intercept fighters and missiles. One possible solution was a radical missile design developed under project Pye Wacket begun in 1958. The Pye Wacket missile was a small flying disc 1.8 metres in diameter, and was formally called the Lenticular Defense Missile (LDM). This shape showed high supersonic stability and lift even at extreme angles of attack, and its evenly distributed mass made the needed super-agility possible. The LDM was originally designed and studied by the Air Proving Ground Center at Eglin AFB and the Arnold Engineering Development Center (AEDC). In June 1959, Convair received a contract to continue development, but records indicate the project was discontinued in 1960. 
On 8 March 1958, American Marine Corps naval aviator Donald Keyhoe, in an interview with Mike Wallace of CBS, claimed deep CIA involvement with UFOs and Agency sponsorship of the 1953 Robertson panel. This prompted a series of letters to the Agency from Keyhoe and Dr. Leon Davidson, a chemical engineer and UFOlogist. They demanded the release of the full Robertson panel report and confirmation of CIA involvement in the UFO issue. Davidson had convinced himself that the Agency, not the Air Force, carried most of the responsibility for UFO analysis and that "the activities of the US Government are responsible for the flying saucer sightings of the last decade." Indeed, because of the undisclosed U-2 and OXCART flights, Davidson was closer to the truth than he suspected. CIA, nevertheless held firm to its policy of not revealing its role in UFO investigations and refused to declassify the full Robertson panel report. 
In 1958 Viktor Schauberger (inventor of the Repulsin) was approached by Karl Gerchsheimer and Robert Donner, with an invitation to come to the US to further develop his inventions. Schauberger spent several months in the US writing articles and drawing sketches. After the project failed because of problems with his US-partners he had to sell all his work and patents to buy a flight ticket back home. He returned to Austria and died in Linz, Austria, on September 25, 1958, 5 days after having returned to Linz. 
The first free-flight test of the Avro Canada VZ-9 Avrocar was conducted on 12 Nov 1959 with Avro test pilot Mladyslaw "Spud" Potocki at the controls. He would hover and zoom as the exhaust from beneath the vehicle blew ice and other debris across the tarmac. The Avrocar hovered happily close to solid ground but became dangerously unstable at heights over 2.5 metres  . In the July 1997 edition of Popular Mechanics Jim Wilson wrote about the VZ-9 Avrocar "Declassified records obtained by PM in the course of its investigation suggest that these marginally performing craft were, in fact, shills intended to disguise the existence of more formidable flying machines."
The hollywood propaganda machine rolled on. February 4, 1960 : in a film based on a Gore Vidal play, Jerry Lewis stars as a flying saucer transported alien trying to get in touch with his human side on Earth in suburbia. 
The CIA admits to deceiving the American public, but don't worry its for your own good:
According to later estimates from CIA officials who worked on the U-2 project and the OXCART (SR-71, or Blackbird) project, over half of all UFO reports from the late 1950s through the 1960s were accounted for by manned reconnaissance flights (namely the U-2) over the United States. This led the Air Force to make misleading and deceptive statements to the public in order to allay public fears and to protect an extraordinarily sensitive national security project. While perhaps justified, this deception added fuel to the later conspiracy theories and the coverup controversy of the 1970s. The percentage of what the Air Force considered unexplained UFO sightings fell to 5.9 percent in 1955 and to 4 percent in 1956. 
Television is an even better propaganda channel than the movies because it delivers brainwashing directly into the home. On January 27, 1967 minature invaders arrived in a miniature flying saucer during an episode of The Twilight Zone  
Betty and Barney Hill were an American couple who claimed to have been abducted by extraterrestrials in a rural portion of New Hampshire on September 19–20, 1961. Inevitably both Betty and Barney reported being abducted on-board a disc shaped craft. Detailed discussion of faked alien abductions are outside the scope of this article.
The Illuminati will use anything to keep flying saucers in the public consciousness; The Flying Saucers was an attraction at Disneyland in Anaheim, California from 1961 to 1966. Guests rode on personal flying saucers on a cushion of air, similar to an air hockey game, which played in a way similar to bumper cars with guests ramming each other with their saucers. 
In 1962, Dr. Paul Moller built a six to one scale model of the XM-2. Two years later in the garage of his residence in Davis, CA he began construction of the full size aircraft. As Moller Aircraft Corporation, Dr. Moller completed construction of this prototype using two 2-cycle McCulloch drone engines which produced enough power to allow the XM-2 to hover in ground effect in 1965. With the success of his first VTOL flight, Dr. Moller began to re-engine the XM-2 in 1966 with two Mercury outboard engines XM-2 in flight under UC Davis sponsorship. The re-engined XM-2 was then flown for the International Press at the UC Davis airport in 1966. In 1968 Dr. Moller received his first patent on this VTOL XM-2 configuration . One can not help but wonder if Moller's efforts are specifically designed to discredit terrestrial attempts to produce a disc shaped aircraft.
The official designation for America’s nuclear flying saucer was the Lenticular Reentry Vehicle (LRV). It was designed by engineers at the Los Angeles Division of North American Aviation, under a contract with the U.S. Air Force. The project was managed out of Wright-Patterson Air Force Base, in Dayton, Ohio, where German engineers who had worked on rocket plane and flying disc technology had been resettled. The LRV escaped public scrutiny because it was hidden away as one of the Pentagon’s so-called black budget items -- that is, a secret project that is incorporated into some piece of nonclassified work. On December 12, 1962, security officers at Wright-Patterson classified the LRV as secret because: “It describes an offensive weapon system.” The project remained classified until May 1999, when a congressionally mandated review of old documents changed the project’s status as a government secret, downgrading it to public information. 
The first public viewing of the Astro Kenetics Corporation VTOL aircraft took place on December 16, 1964. An interesting quote from the text of Astro Kenetics' invitation to the public viewing: ".. when we consider that the United States Air Force has spent seven and one-half million dollars on a circular lifting device of different concept and abandoned the project because of inability to perfect the device." 
Although there are no reports, that I could find, of specific military flying saucer projects in the US 1964 after Flying saucer patents continue to be filed in the US to the present day . From 1965 onwards the US public (and therefore the global population) has been fed a diet of extraterrestrial flying saucers on TV in the movies and, more recently, in computer games.
September 15, 1965 to March 6, 1968 : the Robinson family use a flying saucer named The Jupiter in the original showing of Lost in Space.
Construction of Dr Moller's XM-3 began in 1966. It was a small two-passenger VTOL aircraft. A single ring fan powered by 8 go-kart engines surrounded the passengers to create the lift required for vertical flight. In 1968, Dr. Moller flew the XM-3 in ground effect. This configuration was patented in 1969 . Was it deliberately designed to convince the public the people could not make disc shaped aircraft?
March 30, 1967. Spock and Kirk, along with a four-man security detail, beam down to an uninhabited planet to investigate and find a small, one-man flying saucer.
Jaunary 10, 1967 to March 26 1968 - The Invaders, ran in the United States for two seasons. Roy Thinnes starred as architect David Vincent, who accidentally learns of a secret alien flying saucer invasion, already underway and thereafter travels from place to place, trying to foil the aliens' plots and warn a skeptical populace of the danger.  
One set of pictures, which originated from the site usafflyingsaucers.com is commonly shown on the internet as proof that the US military built flying saucers. usafflyingsaucers.com is no longer active but an archive can be found at . The site purports to provide evidence that the US Air Force built and tested four different disk-shaped aircraft during the 1950s and 1960s. Illustrating the site are several computer generated drawings, models, and images of the flying discs superimposed into pictures of actual planes. Both the site and the illustrations appear to be the creation of Michael H. Schratt. 
Schratt says that the information presented on the site comes from a writer named Jack D. Pickett. According to Pickett, he was asked to visit MacDill Air Force Base in Florida in 1967 to write an article on historic aircraft. Among the planes he says he saw stored at the base were these four saucer-shaped aircraft, and he also claims the base gave him access to hundreds of photos and videos of the craft. Despite this information, Pickett says the Air Force later decided to prevent him from publishing his article about the planes and they have remained a secret to this day.
While it is not possible to dismiss his story out of hand and the existence of these flying disks may be confirmed someday, there is presently no evidence to corroborate the tale. Perhaps more importantly, the pictures created to support these claims ought to be clearly marked as computer generated conceptual images. It is at best misleading and at worst dishonest to present such pictures without explanation since the reader can easily mistake them for being real. The same comment applies to the entire site since it makes rather extraordinary statements written as though they are accepted facts when they are really conjecture and hearsay. The only disclaimer pointing out the conjectural nature of the site appears on one page in very small text that is easy to overlook. These disclaimers ought to be clearly stated at the top and bottom of every page as well as placed on each image to ensure the reader knows they are not genuine photos. 
The Joker was back in Gotham City in February 1968, this time with his sights set on worldwide domination. He plants rumors of an invasion from outer space, then sets out to gather the Beryllium metal needed to build an actual flying saucer.  . There is truth in Batman scripts, it seems.
