Finished playing kickball with my friends in our court and noticed a silver object flying at house/roof top level thru Stonebridge Road. Some how object saw me and turned left behind the homes to confront me. I ran from the object until it cornered me behind the Bell's car. The object hovered above me for one minute and raised its antenna. It seemed the object was studying me, and I was scared! It retracted its antenna and at the speed of light (I can only say) left for outer space. The object was a silver shaped hat. It was approximately 1 to 2 feet high. It made no sounds as it flew thru the air. No air was disturbed. Finally, when it did leave, it made no sounds and did not disturb the air. I did watch a show on UFO Hunters, on the History Channel, covering a UFO sighting in August 1982 in Brazil. It was the same hat shaped UFO that attacked me that was playing with Brazil's air force.
