Ruski kosmonaut, Georgiy M. Grechko, koji je ucestvovao u mnogim misijama Soyuz i Salyut, je izjavio :

"Si j'étais libre de dire ce que j'ai vu dans l'espace, le monde en serait stupéfait. U prevodu : "Kad bi bio slobodan reci sta sam video u svemiru, svet bi bio "zabezeknut"(iznenadjen)

1993, u njegovom malom mestu Kosnikov, blizu Moskve, General-Major avijacije Vladimir Kovalyonok je izjavio, u video-intervju sa Giorgiom Bongiovanni :

"On May 5, 1981, we were in orbit in the Salyut-6 space station.
I saw an object that didn't resemble any cosmic objects I'm familiar with.
It was a round object which resembled a melon, round and a little bit elongated.
In front of this object was something that resembled a gyrating depressed cone.
I can draw it, it's difficult to describe. The object resembles a barbell.
I saw it becoming transparent and like with a `body' inside.
At the other end 1 saw something like gas discharging, like a reactive object.
Then something happened that is very difficult for me to describe from the point of view of physics.
Last year in the magazine Nature I read about a physicist... we tried together to explain this phenomenon and we decided it was a `plasma-form'.
I have to recognize that it did not have an artificial origin.
It was not artificial because an artificial object couldn't attain this form.
I don't know of anything that can make this movement... tightening, then expanding, pulsating.
Then as I was observing, something happened, two explosions.
One explosion, and then 0.5 seconds later, the second part exploded.
I called my colleague Viktor Savinykh, but he didn't arrive in time to see anything.

"What are the particulars ? First conclusion : the object moved in a sub orbital path, otherwise I wouldn't have been able to see it.
There were two clouds, like smoke, that formed a barbell.
It came near me and I watched it.
Then we entered in to the shade for two or three minutes after this happened.
When we came out of the shade we didn't see anything.
But during a certain time, we and the craft were moving together."

U toku Internacionalnog Symposiuma MUFON-a, 1992, General-Major Pavel Popovitch, jedan od prvih kosmonauta, "Heroj Sovjetskog Saveza" ( pozvan kao predsednik Ufoloske Ujedinjene Asosiacije, CIS(ostatak SSSR-a)  ), odrzao je konferenciju na temi:

"Ufology in the Commonwealth of Independent States: Organization Problems".

"Today it can be stated with a high degree of confidence that observed manifestations of UFOs are no longer confined to the modern picture of the world, or the simple refutation of the orthodox natural science paradigm.
The historical evidence of the phenomenon, the singularity of its newly gained kinematic, energetic, and psychophysical features allows us to hypothesize that ever since mankind has been co-existing with this extraordinary substance, it has manifested a high level of intelligence and technology.
The UFO sightings have become the constant component of human activity and require a serious global study.
In order to realize the position of man on earth and in the universe, ufology, the scientific study of the UFO phenomenon, should take place in the midst of other sciences dealing with man and the world...

"The influence the UFO has on people, as well as the effects it produces, should become the items of special research.
The UFO's interaction with the environment, the behavior that it motivates, and its genesis, also present interesting areas for concentrated study.
Today, many specialists have come to the opinion that [UFO] phenomenon research should be taken up along with understanding and comprehension of other unexplained phenomena...
The development of new approaches for the identification and study of energy and information processes will allow for an enthusiastic move toward the comprehension of the phenomenon.
The results of these studies should aid the survival of the people on earth...

"It's necessary to carry out the popular ufological enlightenment, since the probability for a meeting of a person with a UFO exists, and this person should be ready for this event.
Precautionary measures are especially important.
It's necessary to tell the truth, which has been distorted previously by the politically engaged sciences and most recently by ufological dilettantes.
The main purpose of the primary local groups, that of controlling the ufological situation, mustn't be forgotten.
The ufologists should know all the UFO's landing places and contacts in their regions.
They should have relations with the local authorities, and in particular, with the police, the civil defense bodies, as well as information, scientific, and medical organizations."

Werner Von Braun, "otac" i "kreator" Nemackih V2 i Americkih raketa, izjavio je
1959 :

"We find ourselves faced by powers which are far stronger than we had hitherto assumed, and whose base is at present unknown to us. More I cannot say at present. We are now engaged in entering into closer contact with those powers, and in six or nine months time it may be possible to speak with some precision on the matter."

Doktor Hermann Oberth, jedan od "oceva" raketa, u penziji, je izjavio sledece jednoj grupi novinara, 1960 :

"UFOs are conceived and directed by intelligent beings of a very high order, and they are propelled by distorting the gravitational field, converting gravity into useable energy. There is no doubt in my mind that these objects are interplanetary craft of some sort. I and my colleagues are confident that they do not originate in our solar system, but we feel that they may use Mars of some other body as sort of a way station. They probably do not originate in our solar system, perhaps not even in our galaxy. We cannot take the credit for our record advancement in certain scientific fields alone. We have been helped." When asked by whom, he replied, "The people of other worlds."

Doktor Walter Riedel, bivsi direktor Nemacke baze Peenemünde, kolega Doktora Oberth-a, izjavi je u "Life Magazine" 7 aprila 1952 :
"I am completely convinced that they have an out-of-world basis."

Isecak njegove argumentacije :

1. "First, the skin temperatures of structures operating under the observed conditions would make it impossible for any terrestrial structure to survive. The skin friction of the missile at those speeds at those altitudes would melt any metals or nonmetals available."
2. "Second, consider the high acceleration at which they fly and maneuver... If you think of the fact that the centrifugal force in a few minutes of such a maneuver would press the crew against the outside, and do likewise to the blood, you see what I mean."
3. "Third, there are many occurrences where they have done things that only a pilot could perform but that no human pilot could stand."
4. "Fourth, in most of the reports there is a lack of visible jet. Most observers report units without visible flame and no trail. If it would be any known type of jet, rocket, piston engine, or chain-reaction motor, there would be a very clear trail at high altitude. It is from no power unit we know of."

Doktor Lee Katchen, fizicar, ekspert za Atmosferu u NASA-i, izjavio je 7 juna 1968, u odnosu na 7000 slucajeva koje mogao proucavati, bio je ubedjen da su NLO vrsta vanzemaljskih sondi ("probe")

"UFO sightings are now so common, the military doesn't have time to worry about them - so they screen them out. The major defense systems have UFO filters built into them, and when a UFO appears, they simply ignore it."

"The filters cut out all unconventional objects or targets and makes no record of UFOs. Unconventional targets are ignored, because, apparently we are only interested in Russian targets, possibly enemy targets. Something that hovers in the air, then shoots off at 5 000 miles per hours, doesn't interest us, because it can't be the enemy. UFOs are picked up by ground and air radar, and they have been photographed by gun camera all along. "

Doktor James E. McDonald, Profesor atmosferijske fizike na Univerzitetu Arizona, je izjavio 1967 :

"I have absolutely no idea where the UFO's come from or how they are operated, but after ten years of research, I know they are something from ourside our atmosphere."
