Two silver spheres flying together.We were walking in our residential neighborhood and looked up at an interesting shaped cloud and noticed these two objects flying in our direction.They looked shiny and silver with a black area towards the center.They were sphere shaped. They were moving westwards and as they passed over us headed northwesterly until we lost sight over some trees.The sighting lasted a couple of minutes at the most. As they flew they stayed at a level height but moved towards and away from each other in a way not unlike fish swimming. They seemed low, maybe as high as two telephone poles. They did not make a sound.((NUFORC Note: One of three reports from same witness. Date is approximate. PD))
