I was heading to my car to listen to some music and smoke some cigarettes. I have been fixated with the sky and all that it harbors since I have been a child. This is a clear night a two or three hundred feet off of Lake St. Clair here in Michigan, three or four miles north of the lights of the little downtown area in this community so the stars and planets are always brilliant on a clear night such as this. After I exit my back door I look up and scan, as I always do, and my eyes are instantly attracted to a large human aircraft in the western sky traveling northeast, maybe at an altitude of several thousand feet high. There is Selfridge Air National Guard Base about 6-10 miles north/northeast of my house. And I have observed several types of aircraft in both the day and night coming and going in my 7 months of living in this community of St. Clair Shores, Michigan. This plane had two fixed lights on its wings with the red flashing lights in the middle. The second I saw the airplane I saw a bright light, seemingly so close to it as it appeared to me looking from below, that I took a deep breath thinking that it was another plane and if they were at close enough altitudes they were about to collide. But strangely the plane kept going in its path northeast and this light, nothing blinking like the other craft, just a light, it carried on west/northwest. Then my attention was grabbed by a similar star like light in the southern sky traveling east, also in a straight line, as the other light was traveling in its direction, just as the plane was in its. All three objects resembled the same speed to my perception. So I am looking at both of the lights moving and the plane traveling over my head, of course one at a time, but then the light in the western sky abruptly disappeared as I was looking at it! This was very odd because there were no clouds for the object to fly into or over, and there were no other significant celestial objects in that patch of the western edge of the northern sky for it to obscure my view of it, or for me to mistake the light for it. And if anything it should have reappeared. My eyes confirmed that the bright light was gone when I looked back over to the other light in the southern sky traveling east when a few seconds after I re-tracked it, it too disappeared from my sight as I am watching it. I looked back to the airplane and saw it was still traveling on its path northeast. Not saying I am professionally trained or anything but once again I have been obsessive over the sky since I was a child and I have learned a great deal about my favorite sciences astronomy and cosmology and my love for aerospace has taught me how to track with my eyes where a moving object is going and were it should be in the sky after a few seconds have elapsed, if it is man made. The key points I am making to myself and to MUFON is this: I can't stress enough how clear of a night this is, the celestial spheres are bright and it was easy to see both the lights and the airplane and distinguish them from the stars and planets which do not move as the lights and the plane were. I tracked the airplane till it was out of sight. So I am sure that I should have been able to see those lights traveling in their respective paths until they should have disappeared out of sight. And the one traveling northwest should have stayed in sight longer than the plane. But those two lights vanished, and I could no longer see them when they should have occupied the sky for at least the same amount of time as the plane because of where they were when I first observed the three of them. Like everything regarding LIFE, I have my theories, but I can't explain this.
