Mr Z (name withheld) was rowing on a lake at Czluchów in Poland in August 1979 when he saw a dark egg-shaped object moving on the surface. It was apparently making no sound and causing no commotion in the water and shortly after it was first sighted, it moved behind a peninsula and out of sight
A second witness, Mr Y, verified this sighting but also lost sight of the object from his position. As Mr Y approached the site he saw two humanoids in dark clothing moving into the nearby forest. Two dogs owned by Mr Y ran towards the entities who faced them and apparently forced them to run back to their owner.
The witness noticed that the entities were approximately four to 4½ feet (122 – 137 cm) tall wearing something resembling a diving suit with shields across their eyes. The entities appeared to have had hunchbacks or at least some form of enlarged growth between the back of the neck and the shoulders; a rarely reported observation, this is a feature that occurred in the 1954 case in Węgierska Górka, which was not recalled by the witness until 1986, by which time the details of the Czluchów sighting were generally known.
Even more extraordinarily, the entities glided over the ground rather than obviously walking on it, aided, possibly, by the fact that their legs apparently ended at the knees with only an invisible gap between the knees and the ground itself! The witness shouted at them but they glided away even faster and vanished. He never saw them again but he did see a brilliantly lit UFO fly over the treetops approximately 100 yards (91 metres) away from him.
The only physical trace that appears to have been left of the event was that the dogs’ forepaws were paralyzed for six months following the incident.
