One of the most solid sightings from the sixties is the infamous 1960 Yacanto sightning, by a high-ranking officer of the Argentinean Air Force (AAF), Hugo F. Niotti.
On July 3, 1960, then Captain Niotti was driving from Yacanto toward Cordoba. At approximately 4:30 PM, he was in the area of Villa General Belgrano, about 70 Km from the city of Cordoba. He had finished a wide S-curve, when he suddenly noticed a rather close and unusual object hovering near the ground to the right of the road.
Startled, he stopped the car, grabbed his camera, fortunately next to him on the seat, moved a few steps away, and proceeded to take a photo of the object, which was moving slowly. While he was engaged in winding the film to take a second shot, the object started to accelerate and disappeared into the clouds, which as stated, were very low.
The object was conical in shape, with a height of 7-8 meters and a base diameter of 3-4 meters, with its axis almost parallel to the ground and its base facing the witness. It was at a distance of 80 to 100 meters from his location and moving very slowly toward the south, perhaps at 10 KPH, always parallel to the ground. It was rotating, also very slowly. It then accelerated very rapidly, attaining a speed of perhaps 200 KPH in 3 or 4 seconds, and disappeared into the low cloud bank. This sudden acceleration without any sound was inexplicable to the witness in view of his proximity.
The color of the object was a uniform dark gray. The surface was perfectly smooth without joints or rivets and had a definite metallic aspect.
The existence of the horse is fortunate, as it has allowed some estimates of sizes and distances. The Argentinean investigators have performed some photogrammetry using the original negative, and report that the horse is about 80 meters from the road, which places the object at no more than 50 meters from Capt. Niotti.
On the basis of these estimates, the dimensions of the cone were 7 m. in height and 6 m. in diameter, and it was 17 meters above the ground, in good agreement with the numbers indicated by Capt. Niotti.
As an officer of the AAF, Niotti was naturally reclutant to divulge his experience and initially told only a few fellow officers, who persuaded him to send the negatives and copies to the “Revista Nacional de Aeronautica” (RNA); the editors of this official magazine transmitted the photo to the “Servicio de Informaciones de Aeronautica” (SIA), a technical service available to the Air force.
The SIA gave a good bill of health to the photo, and the sighting was reported by the RNA in its issue of November, 1960. It is remarkable that never before or after have the Armed Forces made public the results of a UFO investigation.
In the years to follow, many examinations of this photo have been done and no negative options have been voiced. It is still a total mystery and one of the most solid sightings we have from the sixties.
