UFO seen, possible govt testSaw craft in the western sky for the third night in a row. Craft was in approximatly the same area as before, but started off at a much higher altitude than previous night. Watched it again perform maneuvers for about 2 hours until it finally dropped below the horizon, perhaps landing but I can't be sure. There was alot of air traffic in the area this night, but only one aircraft had an encounter with it. An aircraft was coming from the west, traveling east. It was at a higher altitude than the UFO, and dropped altitude to meet with the UFO. Upon getting close to the UFO, the aircraft immediatly changed flight paths and quickly climbed in altitude, then continued on it's original flight path and continued traveling east. So far the night of 9/12/05 has been the most active night. I am about 95% sure that what I am seeing is a govt test as they are returning to the same area each night at about the same times to fly.
