Description: Taken on January 9, 2005 by Pedro Avila Rubio, as a UFO flew over the Plaza Mexico bullring between 5:45 and 6:00 pm. Rubio obtained impressive video evidence of an unidentified flying object at an altitude of 4000 meters over the municipality of Tlalnepantla in the state of Mexico at 3:45 p.m. The witness described it as a sphere with protuberances in its lower side--making the analogy of a pea with corrugated edges-- which was precisely in the San Mateo air corridor, adding that no aircraft appeared during the recording.
