I was driving north on the 101 in ventura after an exercise class when a "v" shaped group of birght white and blues (with a little red somewhere) appeared in the sky. within seconds of noticing it there the lights shot north and then disappeared as if it when into lightspeed or "warp" speed. it left a slight trail of light behind it which at first made me think i saw a shooting star or comet. i wanted to find a logical explanation but a shooting star would not be that close to earth and i would also be suprised if a plane was that low to earth. i quickly scanned the area around me to see if maybe it was a reflection of lights or something nearby but that portion of the highway, at that time, was nearly empty and no lights were bright enough to create that vision. cars ended up catching up to me a little later and i kept checking my windshield to see if any reflections would make that vibrant of an apparition but never saw anything come close. also, if it was a plane that uses supersonic speed, there was no noise that came from it's immediate, zero to gone, acceleration. if i could outline the image of the craft on my windshield (i drive a ford fusion) then the outline would appear to be no bigger than two and a half inches wide as i sit in the drivers seat.
