I was driving on craig road towards the in and out burger when i stopped at a light near cannery casino. i looked up in the blue sky and thought i saw a bunch of military planes flying in formation. but it was flying so fast and it was very bright. it just didn't seem normal so i kept watching and it stopped after a few seconds and then zipped off in the opposite direction and disappeared. it was triangular in shape, solid and had two rows of very bright lights on the outside of the v. the center was like a diamond shaped cluster of bright lights in the middle. i thought it was probably a ufo or the airforce testing out a new shape but was doubtful anything we've done so far could be that fast, stop on a dime and immediately speed off in a 190 degree about face. very bright. silver and white.
