Here's a strange encounter that occurred at Villa Santina, near Raveo Carnic in the Alps of Italy. The date was August 14, 1947 and the incident happened at nine a.m.
It'a a fairly early case in terms of UFO occupant lore and bears some curious aspects, including the disappearance of all aluminum from the witness's possession:
Seeing two "boys" 50 meters away, he called out to them and began to approach them. When he was within 25 meters, he saw that they were midget-sized beings not over 3 ft. tall, wearing dark blue overalls of translucent material, with bright red belts, collars, and cuffs. Their large heads were covered with broad tight fitting caps.
They had immense round yellow green eyes with vertical slit pupils, and a mere slit of a shaped mouth, which kept opening and closing. Their skin was dull greenish; they walked like robots, with arms hanging.
After a couple minutes stupor, Johannis waved his geologist's pick and called out, asking who they were.
At this, one raised his hand to his belt and a thin puff of smoke was emitted; Johannis found himself flat on the ground, paralyzed, and feeling as if he had received an electric shock.
He saw one of the beings pick up his pick with a green hand that had eight fingers; four of them opposite like our thumbs. Then, with small steps, they slowly walked to the saucer.
A few minutes after they entered the rock crack, the disk rose vertically to about 15 ft above the ground (still on edge, "like a gong") & hovered there while Johannis tried to get up but fell back again. The disc tipped a bit and then took off with a blast of wind that rolled Johannis into the stony riverbed.
It was more than 2 hours before he felt able to walk home. When he unpacked his pack, he found that the aluminum objects in it were missing.
At this time, he had never heard of flying saucers."
This incident was originally reported in Flying Saucer Review Vol 13 #1 from May, 1964 and more recently by researcher Albert Rosales.
