Third Goleta sighting in five weeks.My daughter and I were driving home at dusk heading west. I was telling her about the virtues of looking up quite a lot. One sees all sorts of things; bugs, birds, stars, satellites, etc. I decided to glance up out of the side window of the car and saw an aircraft seemingly triangular in shape. The dusky light made it difficult to discern an actual shape. There were three lights on the object; one on the nose of bright white magnitude -7 appearance, one at each "wingtip", port side red, starboard side amber, each of similar magnitude to the front light. At first the object seemed to be a fighter jet at an approximate altitude of 500 ft traveling directly over the suburb of Goleta. It traveled over the top of our vehicle on a banked trajectory at which point I told my daughter to look up and out of her side window. She immediately located the object and noticed that only the wing lights remained visible but in a matter of seconds appeared white in color. There were no flashing lights. The object's trajectory became due north and, instead of planing off as a typical jet aircraft will do, the object seemed to maintain a strait line up at about 10 degrees and continued due north becoming seemingly a hundred miles away in a matter of thirty more seconds or so. It eventually curved a bit before disappearing still well above the northern horizon.((NUFORC Note: Witness elects to remain totally anonymous; provides little contact information. PD))
