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.

Copiapó Pterosaur (March 17th 1868, Copiapó, Chile)

When the day’s work in the mine was over and all the workers were gathered together waiting for their dinner, we saw arrive through the air on the side of the mine known as “La Ternera” an enormous bird that at first we took for the clouds that a that moment were covering a part of the atmosphere, supposing that it had been separated from other clouds by a chance gust of wind as the object in question approached, causing us great surprise, we could see it was an unknown flying object. It was moving from the northeast to the southeast and its flight was fast and in a very straight line. It passed over just above our heads and we could see the strange structure of its body. Its great wings were covered in brownish feathers, the head of the monster looked like that of a lobster and its eyes open wide and bright like embers, and it seemed to be covered in something resembling thick hair, like a sow. Its body was long like a snake’s and only bright scales could be seen on it, which sounded like metallic pieces when the strange animal moved them. Surprise soon became panic amongst the workers before such a strange phenomenon. Some claim they detected a terrible smell in those moments, a smell similar to arsenic when it is burnt. Others say their senses were not so injured in such an odd manner. The superstitious believe it was the devil himself who they saw pass over, while others remember having witnessed in that city, years ago, the passing of a similar monstrous bird.

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 (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 (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.
