four glowing rectangular shaped lights in a triangular formation moving VERY close to the ground without any sound what-so-ever.four glowing rectangular lights in a triangular shaped patern. triangular shaped o bject appeared as though it were moving sideways. i was in a parade field where sometimes i go out and pray at night and this object flew straight over from behind me and looked as though it was descending. it was about 30-50 feet above me and hesitated before ascending to a higher altitude in front of me, then disappeared no further than 100-150 meters away from me. this object made no sound and being that i am a senior non commissioned officer at the aviation installation here, i can assure you we have nothing like this on fort riley.
