It was 12:42 pm ,I was walking out to my car to plug my phone into its charger(I dont have a home charger). I hear the sound of a small plane flying above. There were alot of small planes in the sky that day most likely because it was the first day that summer was starting to reveal itself. I glance into the air to look at the plane and behind it I see something strange, there where two sphere shaped objects behind the plane, at first glance they looked like 2 balloons some one had release, I kept watching, and then I noticed the objects appeared to be following the plane! I kept watching, they were flying in a straight path then one of the objects circled the other one, between the size and the movements I ruled out it being a balloon about 30 seconds later the objects disappeared from view (from being to far away) at about the same time that I couldn't see the plane anymore. It was very strange and I had never seen anything like it before. I estimate the altitude to be about 3000 - 4000 ft and the size of the objects to be 8 - 15 ft in diameter and where white or creme. seemed to be traveling about a mile or so behind the plane.
