I seen 3 triangle shaped air craft flying at 300 ft in perfect formation, not a sound was heard.One night in east Texas I was working on the drilling rigs just south of Allison Texas. It was around 2 am and there was some fires to the west of us. And we all knew that there was fire planes dropping either water or sand. I looked off to the west and seen 3 air craft moving towards me. I ran down stairs to tell my friend to come see this. The craft was moving so slowly that just as the craft was close enough to be seen, he went back inside. I watched the Triangle shaped craft crusing over head about 300 ft. There was no noise. and they were moving so slow I thought they could fall out of the sky. They was in perfect formation and the formation they flew in was also triangle, and each point on the craft had a light. they flew west for a ways then they cut back heading to the north. I watched them flying until I could no longer see them. Their speed was that of a air craft about to land. the whole thing lasted about 20 min. I was amazed cause I knew they were not of Earth.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information. PD))
