Ufonaut (1865, Siberia, Russia)

While looking for a lost animal from his herd, a shepherd came across a forest glade containing a giant sphere with supports. Accompanying this sphere were a group of large, humanoid 'monsters', and his lost animal lay next to them. The cow was dead, and its stomach was slit open despite the lack of blood or gore visible on the scene. The humanoids bent over the animal, looking like they were studying it or possibly cutting something out of it, according to the witness. Later, they noticed the witness and gestured to him 'in a strange fashion', at which point he ran away from the area in fear.

Ufonaut (Summer 1901, Bournebrook, West Midlands, England)

Frank Warily; ten years old, was taking a shortcut along a path behind his terraced housing estate. Suddenly he came upon a strange object sitting on the grass and thought that it was a workman’s hut. There was a small box-shaped ship’s funnel on top and a door on the side. The object was a greenish blue metallic color with a sheen, half the size of a modern car. Suddenly Frank was confronted by two small beings who stepped down out of the doorway. They were four feet high, clean-shaven, and looked human with no odd features. They wore tight-fitting one piece uniforms with a greenish gray Military look and each wore a dark helmet that masked the eyes and ears almost completely. Emerging from the top were two wires almost like horns on a Viking’s helmet. The wires rose nine inches. One humanoid remained in the doorway. The other moved towards Frank with his arms outstretched, suggesting to Frank to get out of his way. Frank got out of the way and as he was doing this the humanoid scuttled back into the machine and the door closed. There was then a brilliant flash like electric arcing that lit up the perimeter of the object as well as a whooshing sound and the box-shaped craft climbed up into the sky in a curved flight. Frank noticed a pulsating red light at the rear as it ascended. This is one of the earliest reports of creatures specifically identified as ufonauts being observed close to their craft. It is interesting that they appear to have warned the witness to stay away, though this gesture may have been misinterpreted.

Ufonaut (1900, Kuhmo, Lentiira, Finland)

Four children had gone into the swamp and wooded area in order to collect cloudberry. The older children were supposed to keep an eye on the younger ones. An adult had also stayed close by, at the foot of a large pine tree keeping a close eye on the children. Suddenly she became aware that the children were nowhere to be seen; terrified, she ran to the village and immediately a search party was organized and a thorough search was conducted for days, however no trace of the children was found. However weeks after their strange disappearance, the children suddenly appeared again, standing under the large pine tree. After being interrogated by village elders, all the children could remember was that they were approached by some “friendly people” and invited to fly onboard a “device in the air.” According to some of the children, they were able to look down and see the Earth below them. The children were in good health and the adults could not explain how they had gone without food or shelter in the woods for several weeks.

Ufonaut (December 19, 1954, Valencia, Venezuela)

18-year old jockey José Parra, out on a training run, came upon 6 very hairy little men loading rocks into a disc shaped craft which was hovering less than 9 ft from the ground. Parra started to run away, but one of the little beings pointed a device at him that emitted a beam of violet light, and he found himself paralyzed. The entities jumped aboard their craft & it took off. At the site were found footprints “neither animal nor human.”

Ufonaut (438 AD, Istanbul, Turkey)

An earthquake has destroyed Constantinople; famine and pestilence are spreading. The cataclysm has leveled the walls and the fifty seven towers. Now comes a new tremor, even stronger than all the previous ones. Nicephorus, the historian, reports that in their fright the inhabitants of Byzantium, abandoning their city, gathered in the countryside: “They kept praying to beg that the city be spared total destruction; they were in no lesser danger themselves, because of the movements of the Earth that nearly engulfed them, when a miracle quite unexpected and going beyond all credence filled them with admiration. In the midst of the entire crowd, a child was suddenly taken up by a strong force, so high into the air that they lost sight of him. After this, he came down as he had gone up, and told Patriarch Proclus, the Emperor himself, and the assembled multitude that he had just attended a great concert of the Angels hailing the Lord in their sacred canticles. Acacius, the bishop of Constantinople, states, “The population of the whole city saw it with their eyes.” And Baronius, commenting upon this report, adds the following words; “Such a great event deserved to be transmitted to the most remote posterity and to be forever recorded in human memory through its mention every year in the ecclesiastical annals.” For this reason the Greeks, after inscribing it with the greatest respect into their ancient Menologe, read it publicly every year in their churches.

Ufonaut (26 Nov 1972, Zamora, California, USA)

Driving home from her grandmother’s at Bodega Bay, to Zamora, with her two younger sisters, Judy Kendall, 28, expected to be home at approximately 2000. She in fact got home about midnight, finding her parents alarmed over her lateness. She recalled having crossed over Cache Creek Bridge about 2000, and then crossing over it a second time, feeling very tired and barely able to keep her eyes open. Under hypnotic regression, she described feeling an extreme coldness, and of a void around the car; she believed she was floated out of the car and awakened in a round room encircled with windows through which she saw stars. She was on a hard cold surface, and her head seemed to be restrained at times, prohibiting movement. She was able to observe, with restraints removed, two-bucket seats facing a console type instrument panel with a gear like shift; and on her left a table with instruments and a black box. The feeling of cold was intense.
Present were five entities of frightening appearance; with insect like eyes and a pale, or white translucent skin through which was visible a number of red veins. They wore an outfit with a turtleneck top that apparently concealed the lower portion of their faces. She is told that no harm will come to her but the voice does not appear to be spoken normally, sounding more like it came through a megaphone. Three other entities are dressed in similar outfits but apparently lack the bug like eyes of the first. The fifth is an entirely human appearing woman with blue eyes and long black hair, who speaks to her normally, and calms her. She was given an examination, which, she believes, included catheterization; she felt “shaky” experienced pain in her head, and a pain in her side. At times she experienced some difficulty in breathing. She expressed concern about her sisters, one of whom she believed she heard calling out to her in distress. She was not certain that both sisters were brought on board with her. Her feet were examined closely and at one point during the examination, one hand, or arm, was restrained so that she could not move it. The sensation of cold was relieved briefly several times, but severe headaches persisted throughout. Finally a large “scanning” device was placed over her face, and she was unable to see; it gave off a motor sound and when removed, she was again able to see. She was then carried out of the room and next thing she recalled was being “thrown” into the driver’s seat of the car, and her sister was suddenly in the seat next to her. She felt very tired and recalled crossing the bridge for the second time, after which she and her sisters proceeded straight home, arriving four hours later than expected.

Ufonaut (1990, Near Kiev, Ukraine)

A local woman was gathering mushrooms in a field when she was approached by a strange figure more than 2 meters in height. The figure was dressed in a shiny dark diving suit and a helmet. The stranger shone a beam of yellow light at the woman and disappeared, having literally evaporated into thin air. The witness reported a strange aftereffect; according to doctors she completely ceased to attend to the toilet, even after eating and drinking regularly. Apparently the doctors removed the waste manually. Suddenly in 1993 the normal functions of the witness were unexpectedly restored. This account should be traced back through its source and the hospital that analysed the witness should be found. If this can be done, then the story can be either debunked or validated.

Ufonaut (August 16, 1945, San Antonio, New Mexico)

Jose Padilla heard a crash that sounded like a sonic boom, and which he compared to an atomic bomb test. The crashed object was apparently around 35ft in diameter, and 15ft high. Reme Baca (a second witness) described the creatures as thin-bodied beings that resembled praying mantises, but Padilla said that they were three little men who were rushing back and forth, like they were injured. Two days later, the body returned to the site with adults, and the creatures were gone but the craft remained. It would be interesting to follow up on this case and find out what (if anything) happened to the craft, or if photographs were taken of it.

Aquatic Giant (1982, Northern Tian Shan Mountains, Kyrgyzstan)

Either in the Summer of Autumn of 1982, Mark Shteynberg, along with Lt. Colonel Gennady Zverev were conducting periodic training of the reconnaisance divers (also known as frogmen) of the Turkestan and Central Asian military regions. These excercises were taking place in Issyk-Kul, a deep-water lake in the Transiliysk Ala Tau area of Kyrgyzstan. Strangely, a very important official by the name of Major-General V. Demyanko, who was the commander of the Military Diver Service of the Engineer Forces of the Ministry of Defense in the USSR, paid a visit to the officers. Demyanko informed the officers that frogmen on similar training exercises in the Trans-Baikal and West Siberian military regions had encountered 'underwater swimmers' that were human-like but extremely large - being almost three metres in height.
These swimming humanoids were clad in silvery suits that fit tightly around their bodies, and were wearing no equipment or scuba-diving apparatus of any kind despite their depth of fifty metres below the surface. Instead of any human technology, these entities wore sphere-like helmets that concealed their heads. Rightly quite alarmed by these occurences, the local military commander decided to capture one of the aquatic giants. Under the command of an officer, a special group of seven divers were dispatched to carry out this mission. According to the account in which I heard of this anomalous event, the divers apparently were (un)lucky enough to come face to face with one of the humanoids. As the frogmen attempted to capture the giant with a net, the entire group was thrown out of the deep water and up to the surface by some unknown force.
Because the equipment used by the frogmen does not allow surfacing from such depths without the following of the usual decompression process, all the members of the group were struck with aeroebolism (decompression sickness). The only available treatment for this at the time was immediate isolation under decompressive conditions in pressure chambers. Several chambers of this type were in the area, but only one of them was in working condition - and could only contain a maximum of two people. Stupidly, four frogmen were forced into the chamber, and three of them (including the leader of the group) died as a result of this. The rest of them became invalids.
After this event, the previously-mentioned Major-General rushed to Issyk-Kul to warn Shteynberg and Zverev against taking similar actions if the mysterious divers were encountered. Although Issyk-Kul is shallower than the Baikal Lake in which the humanoids were encountered, the depth of the former was apparently deemed sufficient to contain the anomalous beings. The website from which I learnt this story seemed to suggest that the Major-General may have known something that Shteynberg didn't, but this just sounds like needless conspiracy mongering.
It is interesting to note that the staff headquarters of the Turkmenistan Military Region received an order from the Commander-in-Chief of the Land Forces, containing an analysis of the Baikal Lake events and reprimands. This order was supplemented by an information bulletin from the Engineer Forces of the Ministry of Defense headquarters, which listed numerous deepwater lakes in which there had been registered encounters with anomalous things. These things included the appearance of underwater humanoids much like those seen at Baikal, the descent and surfacing of 'giant discs and spheres' (USOs) and powerful luminescence emanating from the deep.
I found this case on two semi-trustworthy UFO websites, and so please take the story with a heaping helping of salt, especially as it seems almost too 'action movie' to be true. If there were actually military deaths caused by aquatic giants, then it would either be so highly-classified that nerdy websites would never know about it, or it would initiate a massive-scale investigation of which the world would have known.

Ufonaut (August 2009, Risør, Norway)

The witness said that he was walking in his local woodland at roughly midday when he came across two 'small lights' floating in front of him. He able to get about 3 meters (10 feet) away from the anomalous object until it 'began swirling faster and faster until a black hole appeared'. A glowing sphere with legs fell out of the portal and started to 'walk' towards him, at which point he tried to run away and hide in the woods but described the automaton as moving through the trees 'like there were no trees'. The witness feared for his life at this point, and so he decided to confront the object. When he grabbed it with his hands, he felt a strange 'electric and vibrating shock' and was promptly thrown backwards into the air, only to land in a nearby farm field. He describes a sensation like he was 'sinking into the ground', and then says that he heard a voice that he believes could have been speaking either Hebrew or Arabic.
He screamed, begging for help, and turned his head to see a white male about 250cm (8 feet) standing there. He went into shock and then an additional three orbs showed up by his side. What he describes simply as 'grey humanoids' then emerged from the spheres, and 'looked angry' at him, whereupon the taller white humanoid pointed at the woods and commanded the small greys to 'roll away'. The man doesn't elaborate further on his story, but he claims to have been with the entities for about 8 hours.
