The disc was silver no lights or seems but we only saw the bottom not the top or sides.when i was about ten years old i was playing in the back yard at my brothers house. and yes my two brothers and my sister were much older than me. anyway, me, my nephew and my two neices heard this humming sound and did'nt know where it was coming from then we saw the edge of this disc shaped craft come right over the top of the trees until it was right over the top of us. It was so big it blocked the sunlight for a whole block, we all started screaming. the adults were inside playing cards, my brother-inlaw heard us screeming and ran to the door to see what was going on. when he looked up to where we were pointing, his eyes got real big, then he ran down the hall to get the shotgun i could tell he was terrified. When he put his hands on the gun, the craft lifted and slowly moved off.((NUFORC Note: Witness indicates that the date of the sighting is approximate. PD))
