My mother always told me she saw this object, seen by many other people in Northern Italy, when she came back from the cinema with dad, the only time they went alone and left me and my brother with my aunt. They saw it from the balcony. My dad's a sea captain and former military, he was astonished. It was a cigar with windows and a trail. They called my aunt to be sure she was safe home, but never told her why.
