On Sunday the 21st of Semptember 2008, 7:30 at nightJust crossed Tailen Bend Bridge towards Adelaide S.A I noticed on the top right hand side of Windscreen a white light moving up and down and moving to my left looking through windscreen it had movedapproximately 12'inches, it then moved towards Adelaide away from me distance maybe 6 inches then white light disappeared to be replaced by a green and red light then disappeared. Maybe one minute later top left of windscreen I noticed 2 white lights close together AND stationary. I saw movement in front of white lights I then noticed the shape of craftsky was a of a grey colour, this shape was darker than night sky craft moved forward again my distance through windscreen maybe 12 inches off went white lights again replaced by green & red lights disappeared. All this time I was trying to locate digital camera in backpack on floor beside me. Maybe 1 minute later looking through drivers side window which was only 1/2 way up 2 white lights moving towards me very slowly. I estimated maybe 300ft-400ft in the sky wow lights went out to be replaced bypulsating green, red, blue & white lights still travelling slowly I had my head out window magnificent I saw under cariage of craft even though it was dark I saw different shades as the lights pulsated. In between I saw the dark shake of a diamond. This went straight over the top of me. The sound was similar to a soft you know ssshh(keep quiet) my head was nearly out of car. I pointed to the sky for the small truck that was 20 metres from me to look up with intentions for him and me to pull over and swapd what we saw. He acceleratedm past me. I was towing a trailer. The next day I remembered that prior to this encounter and before I drove onto bridge that I noticed two very round lights with a slight blue tinge about 18" from my left rear of trailer I checked right mirror no lights, left mirror, lights right mirror no lights, left mirror no lights maybe 30 seconds later I realized nothing had overtaken me . It was a magnificent encounter one that I real! privili ged to have witnessed if I could have got my camera out a bit quicker I would now have the best video or photo of a U.F.O. I know what I saw.
