vw bug sized /flat black colored sphere moving glide like,silent,w/o exhaust trail seen in broad daylightI was relaxing in my backyard pool on mon july 18 my usual day off of work.it was about 6:00 bright blue clear sky a nice enough day to want to be in the pool.I had my headphones on and out of the corner of my eye I kinda see what I thought would be a balloon that got away traveling in the wind.as it enters my line of sight I notice it to be a round sphere at about the size of a vw bug.traveling in a straight path not going up as planes do and fricking silent.it was silverish but when it was at its closest it looked like it was colored flat black with no windows lights fuel or exhaust trail.it was at a heighth too low for any pilot to want to fly safely.I freaked and went to get my mom,but i should of gotten my camera,by the time she came out it was just a blur in its distance.I had no plans on sharing this and havent told anyone because theyd just think I was lying or weird.I only changed my mind after reading reports from others in washington whos accounts and descriptions of the object were identical to mine.when this happened my heart was racing my hair was on edge and I felt somewhat fearful and thats not how I usually react to airplanes or loose ballons.this was real.
