A fiend, my engineering manager at the time, and I were flying electric powered RC aircraft at Cedar Creek Park/Mon Valley RC airfield that evening.
Around 7:00 PM I noticed an extremely bright "star" in the northwest sky. My wife was also with us and we took turns looking at the object for around forty minutes. We sighted the object along our frequency pin board and it appeared to be stationary and in synchronous orbit.
The reason I noticed it was that stars do not show in the Pennsylvania skies at 7:00 PM in July. The object appeared to be a white ring with a dark center. In addition there were curly lines descending from either side of the object, that put my in mind of Jewish dreadlocks. I don't know how else to describe what we saw. All of us agreed with my description.
After about 40 minutes, I happened to be looking through the binoculars, when the object appeared to explode and hundreds of white "shards" shot out of the object at about 280 degrees, and disappeared. In place of the object was a red disk about half the size of the original object. It held for about a three count, dropped straight down, the distance of about four diameters of the red disk, split in two, again about four diameters of the red disk, paused for a three count and then totally disappeared. I have described the objects in relative diameters of the object, as I have no way of accurately relating size.
I later noted in the news that one of the Galaxy satellites (I think G4) went off-line, never to function again, 24 hours after our siting. We have wondered if what we'd seen was a test of an anti-satellite weapon.
Note: The above date is an estimate, as it was a long time ago. I would really like to know what we saw, as my friend and I are both electrical engineers (ret) and have based our lives on facts and science. If you have any ideas as to what it might have been, I'd sure like to know. Thanks! G. Wilson
