UFO Sighting in Petaluma, CaliforniaAbout five years ago, I saw what I thought might possibly be a UFO, around midnight. Before I saw it, there was a loud noise, something like a large diesel engine.At first, I could only hear the loud noise. After looking around the sky and past all of the trees, I finally saw the object. It was coming from the West, over a high hill. It was moving really slowly. It didn���t have any wings, or windows that I could see. The "ship", appeared to be about two hundred feet from the ground, and moving at about five to ten mph.It was a moonless night, but as the ship moved overhead, I could see some writing on the underside, which resembled Egyptian Hieroglyphics.The ship was about 40 feet by 40 feet square, and about a hundred feet tall, and black in color.From the time I first heard it, to the time I finally saw it disappear over the hill to the East of town, it was probably almost an hour.Last year, I was talking to a friend, who said they also saw the same object. They also live in the Petaluma area.To date, I have not seen any more objects of this type.This sighting was in my backyard.I am very interseted in UFO's and their possible origins, and would like to make actual contact with these beings.I am a Sensitive, so I am more in contact with these type of things.It was an interesting sighting, and one that would be nice to see again.
