Carl Sagan, Ph.D. (former professor of astronomy and space sciences, Cornell University)
"It is obvious that Earth is not the only inhabited planet. There is evidence that most of the stars in the sky have planetary systems. Recent research on the emergence of life on Earth suggests that the physical and chemical processes leading to life originate in the early history of most of the planets in the Milky Way. Up to a million planets inhabit civilizations that are ahead of our own. Flight in interstellar space is far beyond our current technical capabilities, but there seem to be no fundamental physical objections that would disable its development in other civilizations. "

J. Allen Hynek, Ph.D. (former chairman, Department of Astronomy, Northwestern University, Scientific Adviser of Blue Book Air Force Project (1947 to 1969))
"Each wave of observation contributes to accumulated reports that are out of the way of analysis by current methods ... They need to be scrutinized if we want to get some answers after twenty years."

"When it comes to the long-awaited solution to the UFO problem, I believe it will prove to be not just another small step in the march of science, but a strong and utterly unexpected quantum leap."

Frank B. Salisbury, Ph.D. (Professor of Plant Physiology, Utah State University)
"I admit that for scientists there is a possible positive mention of the flying plates by extreme heresy, and whoever does such a statement casts the danger of excommunication by scientific theocracies. However, in recent years I have investigated the case of an unidentified flying object (UFO) and I am no longer able to take that idea lightly. "

James E. McDonald, Ph.D. (physicist, Institute of Atmospheric Physics, University of Arizona)
"The most interesting news about UFOs is the observation of non-distant objects reminiscent of machines that are of unconventional nature and unconventional performance characteristics, which is reflected in low altitudes, and sometimes even on the ground. The public is not aware of the large number of these reports that come from credible witnesses. ... When people start looking for these cases, their number is quite astonishing. "

UFO Subcommittee of the American Institute for Aviation and Astronautics (1967)
"From a scientific and engineering point of view, it is unacceptable to simply ignore significant numbers of unexplained observations ... the only promising approach is sustained effort, with an emphasis on overall data collection and objective analysis ... including available extrasensory perception and some software changes."

and the 1986 Project Blue Book:
"From Condon's report, it could be the opposite conclusion that a phenomenon with such a high proportion of unexplained cases (about 30 percent) should generate sufficient professional interest in continuing to study."

Margaret Mead

Margaret Mead, Ph.D. (anthropologist, writer)
"Unidentifiable flying objects exist. It is certain that there is no other explanation for a certain solid case of cases - possibly 20 to 30% of different studies. We can only imagine what purpose lies behind the activities of these quiet, harmlessly crucible objects that are coming again and again to Earth. It seems to me that the most likely explanation is that they just follow what we are ... "

Peter A. Sturrock, Ph.D. (Professor of Space Sciences and Astrophysics and Deputy Director of the Center for Space Sciences and Astrophysics, Stanford University)
"Ultimately, the UFO mystery will not come until this problem is opened and undergoing a large-scale scientific study using standard science-based practices and scientists at universities."

"Although ... the scientific community tends to minimize the significance of the UFO phenomenon, some individual scientists claim that this phenomenon is real and significant ... The main source of verified information for scientists (apart from their own experiments and observation) are articles in scientific journals. Except for rare exceptions, scientific journals do not publish reports on UFO observations. The decision not to publish such articles is done by editors who do so on the advice of reviewers. This process reinforces itself: the apparent lack of data confirms the view that the UFO phenomenon has no real substance and this view prevents the submission of relevant data ... "

Helmut Lammer, Ph.D. (physicist, Institute of Space Research, Institute of Extraterrestrial Physics, Austria)
[Record of departments in Cydonia on Mars]

“It is the author's belief that Viking's data do not have sufficient resolution to identify possible mechanisms for the formation of these objects, although some results so far suggest that they may not be natural. Clearly, these mysterious objects deserve further exploration during the upcoming Mars missions. If one of these missions finds that the face on Mars, the pyramids, and other strange structures are artificial, then the "unlikely" hypotheses of an earlier colonization or an earlier technical civilization would provide a possible answer. "

Professor Hermann Oberth (1894-1989) (German rocket expert and founder of the cosmic age)
"It is my belief that the flying plates are real and that they are spacecraft from another solar system. I think they are probably served by intelligent observers who are members of a race that may have been exploring our planet for centuries. I think they might have been sent to carry out systematic long-range investigations - first people, animals, vegetation, and, more recently, atomic centers, weapons and weapons. "

Dr. Carl Jung Justav
"A purely psychological interpretation is ruled out… discs show signs of intelligent guidance by quasi-human pilots… authorities that have important information should not hesitate to inform the public as soon as possible and as completely as possible."

Dr. Edgar Mitchell

Astronaut Edgar Mitchell, Ph.D. (the sixth man who walked for a month)
"I am an American astronaut and a trained scientist. Because of my position, people in high places trust me. The result is that I have no doubt that aliens have visited this planet. The US government and governments all over the world have thousands of records of UFO sightings that can not be explained. Because I am a scientist, it seems logical that at least some of them must be observing an alien ship. Because I am a former astronaut, military agents who have access to these files are more willing to talk to me than people they consider to be civilians. The stories I've heard from those people who are much more qualified than I to talk about UFOs do not leave me in doubt that aliens have already visited Earth ... "

"When I learned that aliens really existed, I was not too surprised. But when I began to study the observations of their observation ten years ago, I was shocked to see the extent of the evidence. The US government is not silent about alien visits. It would be arrogant from an American like me, supposing that aliens decided to visit only my country. In fact, I've heard convincing stories from governments all over the world, including the British government, who know about alien visits. "

Political, military and intelligence personalities

President Harry S. Truman
"I can assure you that flying saucers, if they exist, are not constructed by any force on Earth."

President Dwight D. Eisenhower
"Beware of the military-industrial complex."

President Gerald Ford
“… Personally, I was very interested in these [UFO] observations, because many of the latest observations have been reported in my home state of Michigan… Because I believe that some of these reports may be a grain of truth and I believe that Americans have the right for a more detailed explanation than the Air Force has given them to this day, I propose that either the Science and Space Committee or the Armed Forces Committee plan a UFO hearing to testify to both government executives and some who claim to have seen UFOs… The firm belief that the American public deserves a better explanation than has been given to them by the Air Force so far, I recommend that a commission of inquiry be set up for the UFO phenomenon. I think we owe people trustworthy information about UFOs and we should make this topic as clear as possible. ”

President Jimmy Carter
"If I become president, I will give the public and scientists every piece of information that this country has about UFO sightings. I'm convinced that UFOs exist because I've seen one myself ... "

President Ronald Reagan
"... when we stop thinking that we are all God's children, whether we live anywhere in the world - I could not help and told [Gorbachev] - to think how easy it would be his job and myself at the meetings that would take place if our world was suddenly endangered by other species from another planet outside the universe ... "

"Maybe we need an external, universal threat to help us recognize our common bond. I sometimes thought how quickly our differences would disappear all over the world if we faced a foreign threat from outside this world. "

J. Edgar Hoover
“I would take them [UFOs], but before we approve them, we must insist on restoring full access to the plates. For example, in the case of LA, it was appropriated by the military and did not allow us to investigate it. ”

General Nathan D. Twining
While he was the commanding general of the Aviation Command, he wrote the following:

"It is my opinion that:

1. Reported phenomena are real and not fictitious.
2. These objects are likely to have a common shape of the disk and the dimensions that seem to be as large as human planes.
3. It is possible that some of the incidents may be due to natural phenomena such as meteors.
4. The specified operating characteristics such as extreme climb speed, controllability (especially in turns), and behaviors that must be considered as evasive maneuvers when viewed or contacted by our aircraft or radar allow us to believe that some objects are controlled either manually, automatically , or at a distance. "

Walter B. Smith

General Walter Bedell Smith (CIA Director, 1950-1953)
"The Central Intelligence Agency reviewed the current situation regarding UFOs that have created massive speculation in the press and have been the cause of concern to governmental organizations ... Since 1947, approximately 2000 has received official reports of their observations, of which 20% is still inexplicable. It is my opinion that this situation has potential consequences for our national security beyond the interests of one agency. A wider, coordinated effort should be made to establish a solid scientific understanding of several phenomena that are apparently the objects of these observations ... "

H. Marshall Chadwell (Deputy Director, Scientific Intelligence, CIA)
"Since 1947, ATIC has received approximately 1500 official observation reports and a huge amount of letters, phone calls and news releases. Only 1952 was 250 official news in July. Of the total number of 1500 messages, the 20 Air Force classifies the percentage as unexplained, and from those received from January to July 1952 classifies 28 as the percentage of unexplained. "

Captain Edward J. Ruppelt (former head of the [1951-1953] Blue Book US Air Force project)
"This message was difficult to write because it talks about something that does not officially exist. It is well known that since the first Flying Plate was recorded in June 1947, the Air Force officially claims there is no evidence of the existence of interplanetary spaceships. But it is not so well known that this conclusion is far from unanimous between the Army and its scientific advisors for one word: evidence. So the UFO investigation is continuing. "

Admiral Roscoe Hillenkoetter (CIA's first director, 1947-1950)
"It's time for the truth to come to light ... Backstage, the Air Force Air Force's senior officers are seriously concerned about the UFO. But through official secrets and ridicule, ordinary citizens are led to the belief that unfamiliar flying objects are nonsense ... I urge Congress to take immediate action to reduce the dangers stemming from UFO secrecy ... "

Major General EB LeBailly (Director of Informatics, Aviation Secretary Office)
"... Many reports that can not be explained come from smart and well-technically qualified people whose integrity can not be doubted. In addition, reports officially received by the Air Force are just a fraction of the remarkable reports that have been published by many private UFO research organizations. "

Congressman William Stanton (Pennsylvania)
"The aviation failed under its responsibility to thoroughly investigate this incident [Watching UFO 17.4.1966 in Pennsylvania] ... As soon as those who have been entrusted with public welfare stop thinking that people can handle the truth, people stop trusting the government."

Wilbert Smith (Canadian Ministry of Transport, Leading Radio Engineer, Magnet Project Leader)
"The whole issue is the most severely concealed by the United States government, with a rating higher than a hydrogen bomb. There are flying saucers. Their modus operandi is unknown, but a small group headed by Dr. Vannevar Bush is concentrating on this. It is considered by the United States authorities as a matter of great importance. "

Lord Hill-Norton, the five-star admiral of the UK fleet
“I am often asked why I'm so interested in UFOs. People think it is strange that someone who has been so closely associated with defense for many years could be such an idiot. I am interested in them for several reasons. First, I have an inquisitive mind that likes things to be explained satisfactorily, and one aspect of the whole matter is that it is quite and perfectly clear to me that UFOs have not been explained. As far as I'm concerned, the "U" means more unexplained (unexplained) than unidentified (unidentified). Secondly, there are lots of other unexplained phenomena that may or may not be associated with UFOs, but I have noticed in connection with UFOs. Thirdly, I believe there is an official secret of UFO investigation by governments, at least definitely in the United States ... Evidence that there are objects that have been observed in our atmosphere and even on a solid ground and that can not be considered by our scientists created objects, even physical forces or phenomena, is a staggering amount. "

Major General Wilfred de Brouwer (Deputy Chief of Staff, Belgian Royal Air Force)
"In any case, the Air Force has come to the conclusion that a number of anomalous phenomena have occurred within the Belgian airspace ... Until now, there has been no single indication of aggression; military or civil air transport has not been compromised or jeopardized. So we can assume that the anomalous phenomena to date do not pose a specific threat ... There will certainly be a day when this phenomenon will be observed by such technological means that leave no doubt about its origin ... "
