Around 9:20 in the evening on Monday, January 23rd I was in the backyard of my home. I heard a helicopter from UC Davis Medcenter start up for take off. About that same time, I looked up and noticed an object with blurry lights pass over the house. I thought it was a lear jet, but it was followed by no sound. It was if the boomerang shaped object appeared as if transparent out of the sky, flew over a tree in our backyard and it shot off into space and disappeared. Normally, on such a clear and quiet night, I would hear sounds of some kind, airplanes, etc., but on this night, the ship disappeared without a single sound. After the experience, I went into the house to tell my husband. I wasn't afraid, but fascinated that after all these years of looking into the sky at the stars, I had never seen anything like this. I have to say I was very pleased that it didn't stop and pick me up...:o)
