Necochea UFO Incident

The Encounter

On the evening of August 29, 1962, at approximately 20:10 hours, truck driver Osman Alberto Simonini was returning from the Malabrigo mink farm near La Dulce when he noticed an unusual object approaching his vehicle on Route 86, approximately 28 kilometers from Necochea. Traveling at moderate speed, Simonini observed a distinctive craft positioned to his left, roughly 3 meters horizontally from his truck and hovering at approximately 2 meters elevation. The object followed a parallel trajectory, maintaining consistent proximity as both vehicle and craft moved along the coastal route.

The craft's appearance was unusual: Simonini described it as resembling two metallic plates joined at their widest sides, with a gunmetal-gray coloration and an estimated diameter of about 5 meters. From the lower section of the object, two intense light beams—one red and one blue—projected downward, each approximately 2 meters in diameter, resembling high-powered headlights. The beams illuminated the ground as the object moved, creating an eerie parallel journey between the truck and the craft.

The Acceleration and Physical Evidence

After maintaining this parallel pursuit for roughly 200 meters, the object suddenly accelerated ahead of Simonini's truck, racing forward approximately 600 meters along the road shoulder at low altitude. The craft maintained its trajectory above the ground as it approached a seedbed near Km 26. Then, in a maneuver that defied conventional aerodynamic expectations, the object executed a sharp right-angle turn and descended into the cultivated field.

Simonini immediately stopped his truck and attempted to approach the craft. As he approached a wire fence separating the road from the field, he placed his hands on the fence wire to examine the area more closely. What happened next provided the most tangible evidence of the encounter: the fence wire was intensely hot, likely to the point of causing burns. The heat emanated from the wire itself, suggesting the object had imparted some form of energy to its surroundings. This physical trace—the thermally charged fence—would become crucial evidence supporting Simonini's account and distinguishing it from a merely subjective sighting.

Official Investigation and Government Documentation

Simonini's encounter did not remain an isolated anecdote. The truck driver reported his experience to multiple official authorities, demonstrating a confidence in the legitimacy of what he had witnessed. He presented his account to the border superintendent of the region, the head of the federal police delegation in Necochea, and Air Force officers stationed in nearby Mar del Plata. Notably, his testimony was formally documented by notary Juan José La Terza, providing legal authentication and establishing an official record.

The Argentine Navy took the incident seriously enough to launch a formal investigation. A Navy commission, led by Captain Omar Paganini, was established to examine the case. The investigation files subsequently became part of the private archive of researcher Roberto Banchs, who preserved and studied Argentine UFO cases throughout his career. Decades later, in 2017 and 2019, the Argentine Navy declassified documents related to the Necochea incident, releasing previously confidential files to the public—a remarkable gesture of governmental transparency regarding UFO encounters.

The official response from air and military authorities was notably non-dismissive. When Simonini and his notary representatives inquired about the phenomenon, they received responses indicating that such aerial phenomena were already accepted as real by military and scientific officials. This represented a stark contrast to the widespread ridicule and denial of UFO reports in other nations, suggesting that Argentine military institutions possessed a more pragmatic and studied approach to anomalous aerial activity.

Argentine Context and Significance

The Necochea incident occurs within a broader pattern of UFO activity over Argentina. The country, with its vast territory, long Atlantic coastline, and strategic position in South America, has been a consistent focal point for documented UFO encounters throughout the twentieth century. Argentina's government, particularly its military and naval institutions, has demonstrated a relatively transparent approach to investigating and documenting such incidents, setting it apart from the widespread secrecy and disinformation campaigns in other nations.

The Simonini encounter remains significant for its combination of credible eyewitness testimony, physical evidence (the thermal trace), governmental documentation, and official investigation by military authorities. The incident exemplifies the type of well-documented, mid-twentieth-century UFO encounter that resists simple explanation while maintaining strong evidential support.
