I was reclining in my lawn chair on my back patio, when a searchlight caught my eye. Since I live within a couple of miles from an Air Force Base, I didn't think much of it, except that only rarely do I see the Base's control tower light. I moved into a shadowed area of my back, on my lawn, and gazed skyward. I positioned myself so that I did not have any street lights or house lights that would have obscured my night vision. I waited and watched for the AF Base control tower light to return, but it never did return. Then I saw the crafts. They were traveling in a straight line, directly above me, approximately 500 feet from the ground, flying in formation, traveling in a straight North direction. There were 3 objects, flying in a "V" formation, all objects appeared to be either grayish or gray/white in color. Each craft was shaped like an "X", or more correctly, like a cross. My best description of these crafts would be something like this: place 4 petals from a daisy, making a cross, with the base of all petals melting together. I am estimating that these crafts were traveling in excess of 150 mph, mainly because of the short duration of my sighting. These crafts were NOT birds, they made NO sound, they DID travel in formation, and they were flying faster than any bird or any single engine airplane that I have ever seen. It appeared to me, that almost immediately after I lost sight of the trio, I saw a small flash of light in the general area that the crafts seemed to be headed. I was and am completely, stone cold sober, and am not under the influence of any medications. What I saw was real.
