Our colleague and friend Spanish researcher Jose Antonio
Caravaca provides an “alien encounter” from August 1956.
What’s interesting to me are the similarities to the Villas
Boas case in October of 1957, one year later than this incident.
And, importantly, as I see it, a recollected “symbol” that
resembles the 1964 Socorro insignia spotted by Police Officer Lonnie Zamora:

One night in August 1956, Orlando Ferraudi, 18, had been
fishing in the Rio de la Plata, on the coast of the city of Buenos Aires.
At about 23.30 hours, something approached from behind
Orlando. It was a humanoid about two meters tall, blond, with very short hair,
white skin with honey colored eyes.
He clothed in a one-piece, yellow/orange suit that emitted
little "sparks." The suit had a hood that fell on the back.
This "being" provided a mental message that calmed
the witness.
The humanoid then took out a small circular object that gave
off a very intense light.
From the river came an object, in the form of inverted
saucer, about 70 meters in diameter.
When it reached Orlando’s and the humanoid’s
position, it deployed a metal ramp from which Orlando entered the object.
Inside was a bright room with a little girl called Elena, 11,
who was allegedly abducted from her home in Villa Mercedes (San Luis
Province - Argentina).
The ship rose and traveled outside the atmosphere. After
several minutes it descended and submerged itself in the Caribbean, for a few
seconds of underwater navigation. Orlando saw on the sea-bed a kind of
transparent dome, under which there were several saucer-like craft.
Orlando estimated the structure to be about five or six
hectare.
He was taken to another room, which contained two stretchers
and strange instruments.
Orlando was given a thick liquid similar to honey without any
taste, and some pills that looked like little colored eggs.
He fell asleep, on a pillow with lights.
After waking he was shown the inside of the ship and given
several explanations on different issues and matters.
He was returned to the shore.
Orlando remembered seeing a strange symbol that was closely
related to the aliens.
