One silver domed disc was observed by one female witness at a hospital for two minutes (Casalvieri De Panasitti). A humming sound was heard. A humanoid was seen.

Adela Casalvieri, night nurse at the Neuropsychiatry Hospital, heard a loud penetrating humming noise outside in the hospital courtyard. Going out to see what caused it, she observed at a distance of 20 meters a landed object, in the shape of two saucers edge-to-edge and brightly luminous, in the middle of the courtyard. A luminous red ray was directed at her and she found her legs paralyzed; putting her hands up to her face for protection, she found she was unable to move, as well. She remained immobilized for a number of minutes, until the red beam was extinguished. At this time the object ascended vertically, then moved off rapidly to the south, barely clearing the wall around the courtyard. Before it disappeared she was able to observe several human like figures through square portholes that encircled the object; these moved back and forth, passing each other, and were visible only from the waist up. Imprints were found at the landing site and several small potted trees were burned. Mrs Casalvieri had first-degree burns of the face and hands, and parts of her cap and clothing were burned; in addition, her watch, which had stopped at 0130A, was found to be radioactive, as was her ring.
