Pierre Cavallo, 50, a cinema projectionist, was walking home, pushing his bicycle, and collecting snails, when he was surprised by the apparition in the sky of an orange luminous cigar with blue spangles in its interior. This passed silently in 20-30 seconds, leaving a trail of orange sparks. Astounded, Mr. Cavallo remained where he was for about 40 seconds. Then he sensed a presence near him, and, turning his head, saw a face of extreme pallor, with blue eyes, the head perfectly bald, and the mouth mixed in a “sanctimonious smile.” A hedge only 3 ft high hid the body. After staring for some seconds, Cavallo jumped on his bicycle and sped away.

An occupant described as a broad- shouldered dwarf wearing clothing that covered the head and the trunk was also seen. His arms and legs were covered with tweed like cloth fastened at the wrists and ankle. He filled a shiny pail with water and handed it to someone inside the craft. He then appeared to notice Black and jumped into the craft, which made a hissing sound and departed.
