I stopped on North Livermore Road to make a phone call. It was starting to get dark. While looking for the number I noticed two lights just over the hills. As I’m looking out my passenger door window I keep looking at the lights because I felt they were too low for a jet on approach because the lights looked liked landing lights. There is an airport nearby but not for jets. But I was sure the lights were too bright and too far apart to be a small aircraft. As the lights approached they got further apart but continued in unison. At some point I got out of the car because I could no longer see both lights and everything seemed much darker, like no lights at all. When I stood up I could see the outline of something seeming to cover the sky. I looked to the west to see the tip or outline of this craft. It had sort of a red glowing on two sides but, they were not attached to wings but to the sides of the object. It must have been 1000 or more feet wide and at least twice that long. It seems in my mind to be much bigger but I can’t understand how. It made no sound as it went over me and turned west towards San Francisco. I could make out its basic design as it ascended and flew out of site towards the northwest. The back of the craft was huge and had two big white lights that you would have to say were engines. It looked like a giant black battleship in the sky. So much larger than my mind could imagine something being able to fly and no noise. NOTE: The above image is a rendering.
