Around 1 a.m. about 4 UFOs started flying in formation with their lights flashing in secession. Within 5 minutes of the first 4 UFO lights, about 16 more UFOs joined and they began flying around in a fluid like motions huddling together and then dispersing. The UFO lights were very high in the sky, and moved too quickly and changed direction too rapidly to be any known aircraft. After about 2 hours these UFOs started to disperse a few at a time until they were entirely gone from sight. source nuforc.org
