Italian Professor Saw a Glowing Sphere Vanish and Reappear

Near the city of Sassari, Italy, Professor Giovanni Battista Sias observed a glowing sphere in the sky. It moved rapidly from east to west, vanished, and then reappeared.

Behind it, a narrow trail of light remained. The sighting was reported in the local newspaper the next day and later reached the US Air Force. What happened after the report got there—and why was it documented?

A Blue-Green Sphere in the Sky

Sias described a brilliant sphere, appearing slightly larger than a full moon. Its color was blue-green, and its sheen looked silvery. On its right side, he noticed stripes that resembled metal.

The sphere traversed the sky from east to west at a very high speed. During its movement, it vanished and then reappeared, leaving behind a narrow trail of light, like a bright ribbon. Sias recounted this to a US Air Force representative who was visiting Rome.

What Was Done with the Report?

This event occurred in 1952. The next day, a report about it was published in the local Italian press. More than a year later, the Air Force representative in Rome forwarded a translation of the news item to US Air Force personnel. Subsequently, he also interviewed Sias, who had reported the sighting.

The Air Force kept the information in a record intended to collect details for future investigation. This record included both the newspaper article and Sias's description from the interview. The record documented what was reported, not just the headline that appeared in the newspaper.

What Remains Unknown

The record does not explain what the sphere was, nor does it offer a conventional explanation for the sighting. It documents Sias's description but does not determine what caused the light or the movement.

A narrow trail of light remained behind, and the sphere vanished and reappeared. What crossed the sky near Sassari?
