I'm 78 yrs old and haven't talked about this to very many people over the years. In 1988, on a sunny Easter day at 2:00 PM ,I was sitting on my deck enjoying the warm weather. I heard a Passenger Jet flying overhead. Not sure of the altitude but it was leaving contrails so I'm guessing over 15,000 ft. or higher. The Jet was quite visible. About 1/4 mile behind the Jet was a round silver object about the same size as the Jets fuselage, it was following the Jet. At first I thought the Jet was pulling balloon but that didn't seem reasonable. I viewed it for about 30 seconds and all of a sudden the object shot off at a 45 degree angle, to the north west and disappeared over the horizon in less then a second. It was almost like it knew I was looking at it? Whished I'd never seen it, hard to deal with something something I can never explain after all these years.
