Case description
The brief Calcerosa entry concerns two twelve-year-old boys who said they encountered three exceptionally small figures in Italy in 1954. Its familiar catalogue version names them G. Marziano and P. Santucci and assigns 25 November. Crucially, the surviving HUMCAT sheet includes an explicit correction: the date should be 25 October, the place Col Cerasa di Cingoli in Macerata, and the first witness M. Giampieri. These corrections are more precise than the imported year-only listing but do not erase the conflicting older version.
In the short account, the boys suddenly noticed three figures approximately fourteen inches, or thirty-five centimetres, tall, with very large heads and lead-grey skin. They entered a small vehicle concealed near bushes; the earlier summary places it roughly ten metres away. Two pointed propellers at its front began turning, and the machine departed with a hissing sound. The correction adds metallic coveralls and describes a keg-shaped vehicle approximately five feet long and two feet in diameter, rather than the spherical machine in the older abstract.
That same addendum includes a further reported departure effect: a large fireball left at about sixty feet altitude, which burst before reaching the ground. It cites an Italian catalogue drawing on Il Messaggero and a later Gruppo Bilancia investigation. These remain reported descriptions, with incompatible craft shapes across versions. The plate follows the corrected keg-shaped, metallic-coverall account at the boarding stage; it does not combine a departure fireball with a supposedly simultaneous close examination or infer a medical effect from an automatic database tag.
