Other over Norfolk, MA

The report, as filed

I was in my pool, looking up and heard an airplane above. I looked and saw a small personal plane flying over head, to the left of the plane I saw an object that I initially thought was a hawk. I have chickens so I was wary of having hawks overhead so I watched it to see if it would come down from where it was. It was very high up in the air, it had what I could imagine was a wing span. I was waiting for it to circle the air the way hawks do and it didn't, it just hovered, then it moved slowly. I figured it was a hawk surfing the wind. But it still didn't behave like a hawk. So I thought maybe it was a vulture or an eagle. I came to the conclusion that it was a type of eagle or vulture. I kept staring at it, it must have been about 1 minute by this point. The airplaine was out of sight. Then all of a sudden, it changed direction and shape and what looked like a bird then looked like a dark ball or sphere/disc with a slight shine to the top of it and it seeme! d like it was rotating while it quickly descended downward at an angle of about 45 degrees with a purpose, no wavering it was a clean line,toward the direction where the plane was headed although the plane was not on a descent. the object had no wings at this point. I wondered if it was a drone? I looked up drones with retractable wings but couldn't really find any. I also looked up drones that look like birds and couldn't find a match. I know drones have lights, but this thing didnt have any. So strange.
