Low flying, sparkling, cigar shaped, wingless, silver object silently moving through northern GA sky.October 25, 2012 This morning I was out on the deck behind our house. I looked up toward the top of a tree that was changing colors in the autumn and noticed a fairly low flying silver object that I first took for an airplane, since it had the sleek, cigar shape of an airplane’s fuselage. Normally I wouldn’t have even noticed it, because it made no noise at all. I had my glasses on, so I was able to see it well.I watched as it soundlessly glided in a southern direction through the sky, and I tried to identify whether it was a larger jet that perhaps had taken off from the airport, or a smaller aircraft. It had no contrail, so I looked for its wings and to my surprise it had none. It either greatly sparkled in the sun, or was emitting fluctuating bright light. I saw no windows on the object. Then, I got concerned thinking it might be either a large missile directed at some point in the USA or a UFO.As it headed out of sight, I began to experience a strong feeling of dizziness, unbalance, and a general feeling of malaise which passed in several minutes after coming indoors.
