Crescent shaped lights that emitted green light and then moved jerkily and then hovered in placeI walked onto my deck at 19:50 and a flash caught my eye in the western sky. I live only 6 miles from the Kansas City airport so I am accustomed to seeing planes takeoff and land. I looked at it for a time and realized that it was making jerky movements preceded by a green flash. It was a light at high altitude, crescent shaped. I watched it for half an hour and it moved repeatedly, then I sighted two more in the southwest sky. I also witnessed what appeared to be planes with red and white flashing strobes, and I assumed that it was military observation of the phenomenon. Then I sighted two more in the southern sky. After 22:00 the lights from a nearby shopping center were dimmer and I was able to see more right overhead and in the eastern sky. I became unable to count accurately due to the number of UFOs in the skies.Until last night, November 6, 2012, election night, I have been a skeptic and now I am a believer. I phoned my sister in Syracuse, NY, who is professor emeritus SUNY, during this sighting, since she attends UFO conferences and is a staunch believer. She questioned me and was sure that I was in fact witnessing an event. They looked different from stars which appear as a bright light that twinkles sometimes and do not move in the manner of water bugs on surface tension on a body of water like these objects did. I am not sure of the exact duration of the event, because the election coverage was on TV and I went inside to see who was elected. I ceased watching at 22:00 and went back out at 00:30 and they were no longer there. The constellations had changed position, but that was all I saw in the skies by that time.
