Towards march 2002, i went along street paolo reti that from ge-sampierdarena leads to ge-campasso in my office where i tried to start a business on their own in via miani, it was about 6:30 pm and i was on foot. i was walking with the railway that runs along the river to my left. looking up i look at what could be a ufo in retrospect. i decided not to say anything, i was afraid that the thing could degenerated into panic or that someone would tell me that i was crazy, if it would gone away and had turned out no longer visible; i continued to observe it, it had a diameter of about 5 meters, it was about 70 meters away as the crow flies, it flew over the railway and in that area there is also a industry of superconducting materials; the sky was clear, i could see it well. the consistency was metallic, opaque gray and did not emit lights. the shape of the object was "star", ie an hexagonal (or pentagonal) core with six (or five) "arms" consisting of parallelepipeds embedded on the central core and revolving around its axis with an angular velocity, i would say, about 30-60 degrees per second. the axis of rotation was not fixed, but swayed like that of a spinning top that is about to stop and the object moved towards the mountain on which the sanctuary called madonna della guardia is located. the whole scene lasted about 30 seconds, then a series of buildings covered the view and the object "disappeared".
