Black cilinder with a crome colored "strap" arond its middle, cylinder stood on end, No lights and nothing supporting it

On April 2nd 1985 I say a UFO. I was flying a Lake Buccaneer (N8003Q)  at approximately 3000 ft near Wallops Island, Virginia.  A passenger and I both  saw and tracked it for about 30 seconds before we passed it on our starboard side.
It was cylindrical, jet black, shiny like glass and had a wide chrome colored ring around its mid-section. We had been a first looking for wings while it was at a distance, but as it got closer and there were no wings, we looked  for a cable and balloon above it, but there was none.
My airspeed at the time was about 120 mph and it was a beautiful clear day,  but turbulent air.  Since it took about five seconds for us to pass, it was standing  still or moving in the same direction as we were.  If it were 100 feet away (which  I would say to be the case) I estimate it to be about 30 feet high.
For some reason it didn't seems such a big deal, and I never reported the incident to anyone.
