During the very early days of air travel, unidentified flying objects were not referenced when folks looked to the skies. On November 17, 1896, hundreds in Sacramento watched three lights, illuminating a dark and stormy sky. The unusual object traveled 350 yards as it skirted rooftops. Five days later the object took a half-hour to cross another town where spectators claimed to have seen two men peddling a bicycle-type frame, attached to the object. Later that night the object was sighted above San Francisco as it was witnessed by thousands. The airship cruised above the Cliff House, identified by a searchlight. Numerous sightings of airships were reported until May, 1897. It was the Mongolfier brothers who began flight balloons in 1783.
